Design Theory

Design Theory

Comprehensive knowledge base for architectural design philosophy, critical theory, compositional principles, precedent analysis methodology, and design critique frameworks. Invoke this skill when addressing questions about design philosophy, architectural movements, theoretical underpinnings of design decisions, or structured critique of architectural proposals.

Section 1: Architectural Design Philosophies

1.1 Rationalism — Structure as Expression

Rationalism holds that architectural form should derive from logical structural and programmatic reasoning. The building's truth lies in its clarity of organization and the honest expression of its constructive logic.

Core Tenets:

• Form follows structural logic and material behavior
• Spatial order derives from geometric and mathematical systems
• Ornament is secondary to tectonic clarity
• Repetition and modular coordination create visual coherence

Key Figures: Auguste Perret, Pier Luigi Nervi, Louis Kahn, Aldo Rossi, Giorgio Grassi

Canonical Works:

• Kimbell Art Museum (Kahn, 1972) — cycloid vault shells spanning 30.5 m (100 ft), natural light slits at vault crowns
• Palazzetto dello Sport, Rome (Nervi, 1957) — 58.5 m diameter ribbed dome, 1,620 precast concrete V-elements
• Gallaratese Housing, Milan (Rossi, 1974) — archetypal column-and-lintel repetition, 182 m long block

Design Application: Begin with the structural bay as the generative unit. Derive spatial hierarchy from column grid spacing (typically 6.0 m, 7.5 m, 9.0 m, or 10.8 m grids in reinforced concrete). Express the load path visually. Eliminate non-structural partitions where possible to reveal the primary order.

1.2 Empiricism — Experience-Driven Design

Empiricism prioritizes direct human experience, sensory engagement, and contextual observation over abstract theory. Design decisions arise from studying how people actually inhabit and move through space.

Core Tenets:

• User observation and post-occupancy data drive design
• Spatial sequences are composed for experiential richness
• Material selections respond to tactile and visual perception
• Context (climate, culture, daily rituals) shapes form

Key Figures: Alvar Aalto, Ralph Erskine, Jorn Utzon, Herman Hertzberger, Giancarlo De Carlo

Canonical Works:

• Paimio Sanatorium (Aalto, 1933) — patient rooms oriented for morning light, handrail profiles designed for tubercular grip
• Byker Wall, Newcastle (Erskine, 1974) — 1.6 km perimeter wall shields against north wind, south-facing terraces capture sun
• Centraal Beheer, Apeldoorn (Hertzberger, 1972) — 9 m x 9 m tartan grid of habitable blocks, 1,000 employees given agency over individual workspace configuration

Design Application: Conduct behavioral mapping during programming. Walk the site at dawn, midday, and dusk. Photograph existing pedestrian desire lines. Record ambient sound levels (target < 35 dB in work areas, < 45 dB in circulation). Document prevailing wind direction and velocity. Let these observations generate the parti rather than imposing a geometric diagram.

1.3 Phenomenology — Atmosphere, Body, Perception

Phenomenological architecture foregrounds the lived experience of space — the qualities of light, material, temperature, sound, and movement that constitute atmosphere. Architecture is understood through the sensing body rather than the detached eye.

Core Tenets:

• Architecture is experienced multi-sensorially, not just visually
• Atmosphere is a legitimate design objective (Zumthor's "architectural atmosphere")
• Materials are valued for their tactile and temporal qualities (patina, weathering, warmth)
• Thresholds, transitions, and spatial compression-expansion sequences shape experience
• The body in motion is the measure of space

Key Figures: Martin Heidegger (philosophical ground), Christian Norberg-Schulz, Juhani Pallasmaa, Peter Zumthor, Steven Holl, Alberto Campo Baeza

Canonical Works:

• Therme Vals (Zumthor, 1996) — local Vals gneiss quartzite in 31 mm, 47 mm, and 63 mm courses; water temperature progression from 14 C to 42 C; sound of water as spatial marker
• Chapel of St. Ignatius, Seattle (Holl, 1997) — seven "bottles of light" in different colors for liturgical program; beeswax-finished walls
• Bruder Klaus Field Chapel, Mechernich (Zumthor, 2007) — 12 m tall truncated cone, 112 tree trunks burned out to form interior surface, oculus open to rain and sky

Design Application: Compose spatial sequences as atmospheric scores. Map the visitor's journey through compression (2.4 m ceiling) to expansion (6.0 m+). Specify materials by touch: rough-sawn timber vs. honed stone vs. brushed steel. Design light as a material — calculate the sun's path and place apertures to create specific light conditions at specific times. Target a minimum of 3 sensory engagements per major space (visual, tactile, acoustic).

1.4 Pragmatism — Performance-Driven Design

Pragmatism evaluates architecture by how well it works: functionally, economically, environmentally, and socially. Performance metrics replace aesthetic judgment as the primary design criterion.

Core Tenets:

• Measurable performance outcomes drive design decisions
• Life-cycle cost analysis (LCCA) over 30-60 year horizons determines material and system selection
• Energy Use Intensity (EUI) targets are set at project inception (e.g., < 100 kBtu/ft2/yr for offices)
• Post-Occupancy Evaluation (POE) validates or refutes design hypotheses
• Iterative prototyping and testing replace singular design gestures

Key Figures: Buckminster Fuller, Cedric Price, Norman Foster, Renzo Piano, Bjarke Ingels

Canonical Works:

• Centre Pompidou, Paris (Piano + Rogers, 1977) — all services externalized to free 7,500 m2 column-free floors, 48 m clear spans
• 30 St Mary Axe "Gherkin," London (Foster, 2004) — diagrid structure reduces steel by 21% vs. conventional frame, natural ventilation for 40% of occupied hours
• VIA 57 West, New York (BIG, 2016) — courtyard-tower hybrid maximizes air and light while achieving 76,180 m2 (820,000 ft2) residential GFA on a constrained site

Design Application: Establish quantitative performance targets before sketching: target EUI, daylight factor (minimum 2% in occupied spaces), ventilation rates (ASHRAE 62.1: 8.5 L/s per person for offices), structural efficiency (kg steel/m2), and cost/m2. Use energy modeling (EnergyPlus, IES VE) from concept stage. Evaluate every design move against these metrics.

1.5 Critical Regionalism — Frampton's Six Points

Kenneth Frampton's 1983 essay "Towards a Critical Regionalism" argues for an architecture that resists both the placelessness of universal modernism and the sentimentality of historicism.

Frampton's Six Points:

1. Culture vs. Nature: Architecture mediates between the universalizing tendency of civilization and the particularities of local culture
2. The Rise and Fall of the Avant-Garde: Resist rear-guard historicism and avant-garde abstraction equally
3. Critical Regionalism and World Culture: Adopt universal technique but inflect it with local conditions
4. The Resistance of the Place-Form: Ground architecture in topography rather than impose upon it (build the site, not on the site)
5. Culture vs. Nature (Reprise): Modulate climate through architectural means — loggias, brise-soleil, cross-ventilation — rather than hermetic mechanical systems
6. The Visual vs. the Tactile: Foreground the tactile (materiality, light, temperature) over the purely visual (the photograph)

Key Figures: Kenneth Frampton, Tadao Ando, Glenn Murcutt, Balkrishna Doshi, Geoffrey Bawa, Charles Correa, Sverre Fehn

Canonical Works:

• Bagsvaerd Church, Copenhagen (Utzon, 1976) — concrete shell vaults evoke Danish cloudscape, precast exterior with in-situ interior
• Marika-Alderton House, Northern Territory (Murcutt, 1994) — operable wall panels for cross-ventilation in tropical climate, raised on steel piers to allow air flow beneath
• Indian Institute of Management, Ahmedabad (Doshi, 1977/2012 campus) — brick construction responding to Gujarat climate, deep overhangs, stepped terraces, water courts

Design Application: Map the site's genius loci: prevailing winds, solar geometry, topographic contours, local building materials within 500 km radius, vernacular construction techniques, and cultural use patterns. Develop the building section as a climate-responsive device before the plan. Use local materials for primary enclosure (target > 60% by weight from regional sources within 800 km per LEED MRc5).

1.6 Parametricism — Schumacher's Tenets

Patrik Schumacher's 2008 manifesto declares Parametricism the new epochal style after Modernism, arguing that digital tools enable continuously differentiated, relationally complex architectural and urban fields.

Core Tenets (Schumacher's Taboos and Dogmas):

• Negative heuristics (taboos): Avoid rigid geometric primitives (boxes, cylinders), avoid simple repetition, avoid collage of unrelated elements
• Positive heuristics (dogmas): All forms must be soft (nurbs-based), all systems must be interdependent (structure/envelope/program parametrically linked), differentiation must be gradual and lawful (no abrupt transitions)

Key Figures: Patrik Schumacher, Zaha Hadid, Greg Lynn, Hernan Diaz Alonso, Neri Oxman, Marc Fornes

Canonical Works:

• Heydar Aliyev Center, Baku (Hadid, 2012) — continuous surface folding from ground to roof to wall, 57,500 m2, GRP panels over space-frame
• Galaxy SOHO, Beijing (Hadid, 2012) — four continuous volumes with interconnecting bridges, 332,000 m2
• Morpheus Hotel, Macau (Hadid, 2018) — exoskeleton with free-form voids, 40 stories, 770 rooms

Design Application: Define design parameters (site boundary, program areas, solar access, views, structural span) as variable inputs to a computational model (Grasshopper/Dynamo). Establish relationships between parameters (e.g., facade density varies with solar gain — 40% open on north, 15% on west). Generate multiple options through parameter variation. Evaluate with quantitative fitness criteria. The designer's role shifts from form-maker to system-designer.

1.7 Ecological Design — Regenerative and Biomimicry

Ecological design moves beyond sustainability (doing less harm) to regenerative design (creating net positive environmental impact). Biomimicry applies nature's 3.8 billion years of evolutionary strategies to architectural problems.

Core Tenets:

• Buildings as ecosystems: produce energy, clean water, sequester carbon, support biodiversity
• Cradle-to-Cradle material philosophy: all materials are either biological nutrients (compostable) or technical nutrients (infinitely recyclable)
• Living Building Challenge 4.0: seven performance areas (place, water, energy, health, materials, equity, beauty) — the most stringent green building standard
• Biomimicry design spiral: identify function, biologize question, discover natural models, abstract design principles, emulate

Key Figures: William McDonough, Janine Benyus, Ken Yeang, Michael Pawlyn, Neri Oxman, Bill Reed

Canonical Works:

• Bullitt Center, Seattle (Miller Hull, 2013) — net-zero energy, net-zero water, composting toilets, 242 photovoltaic panels, 14.2 kBtu/ft2/yr EUI
• Eastgate Centre, Harare (Pearce, 1996) — termite-mound-inspired passive ventilation, 90% less energy than conventional AC in sub-Saharan climate
• Bosco Verticale, Milan (Boeri, 2014) — 900 trees, 5,000 shrubs, 11,000 perennial plants on two towers (110 m and 76 m), equivalent to 20,000 m2 of forest

Design Application: Set regenerative targets: net-positive energy (produce 105% of consumption), net-positive water (harvest > consumption + 10% for habitat), carbon sequestration (use mass timber, hempcrete, or biochar concrete to store > embodied carbon within 30 years). Use the Biomimicry Design Spiral at concept stage: what function does this building need to perform? How does nature achieve this function? Abstract the principle and apply it.

1.8 Social Architecture — Participation, Equity, Community Agency

Social architecture foregrounds the political and social dimensions of design: who designs, who is designed for, who benefits, and who is displaced.

Core Tenets:

• Participatory design processes (not just consultation but genuine co-design)
• Design justice: center the voices of those most impacted by design decisions
• Incremental development: design frameworks that communities can build out over time
• Commons and shared spaces as priorities over private enclosure
• Anti-displacement strategies: community land trusts, inclusive zoning, affordable unit integration

Key Figures: Giancarlo De Carlo, Hassan Fathy, Alejandro Aravena, Yasmeen Lari, Francis Kere, Anna Heringer, Teddy Cruz

Canonical Works:

• Quinta Monroy, Iquique (Aravena/ELEMENTAL, 2004) — half-houses at $7,500 each, 93 families, incremental design allowing residents to expand from 36 m2 to 72 m2
• Gando Primary School, Burkina Faso (Kere, 2001) — community-built with local laterite clay, raised corrugated metal roof for stack-effect ventilation, $50,000 budget
• METI School, Rudrapur (Heringer, 2006) — bamboo and earth construction, built by local craftspeople and students, cave-like ground floor, open bamboo upper floor

Design Application: Conduct community asset mapping before design begins. Hold minimum 3 participatory workshops per project phase. Use 1:1 mock-ups for critical spatial decisions. Design 15-20% of spaces as flexible commons adaptable to community-determined uses. Establish a post-occupancy community stewardship plan. Budget for community capacity building (training local labor in construction techniques).

Section 2: Design Thinking Frameworks

2.1 RIBA Plan of Work 2020 — Stages 0-7

The Royal Institute of British Architects (RIBA) Plan of Work organizes the design and construction process into eight stages. Each stage has defined deliverables, responsibilities, and information exchanges.

2.2 AIA Phases

The American Institute of Architects defines five traditional project phases:

2.3 Integrated Design Process (IDP)

IDP front-loads collaboration, engaging all disciplines (structural, MEP, landscape, sustainability, cost) from Stage 0/1 rather than sequentially.

Key Principles:

• All consultants present at first design charrette
• Energy modeling begins at concept stage (not DD)
• Cost estimating is continuous, not stage-gate
• Contractor input during design (IPD/Design-Build contracts)
• Target Value Design: set cost target first, design to meet it

Quantitative Benefits (per AIA/COTE studies):

• 15-30% reduction in construction cost vs. traditional sequential process
• 20-40% reduction in energy use through early passive design decisions
• 50-70% reduction in RFIs during construction

2.4 Evidence-Based Design (EBD) for Healthcare

Developed by the Center for Health Design, EBD uses research findings to inform design decisions in healthcare environments.

Core Methodology:

1. Define EBD goals linked to outcomes (reduce patient falls, reduce HAIs, reduce staff fatigue)
2. Gather evidence from peer-reviewed research (CHD Pebble Project database)
3. Translate evidence into design hypotheses (single-patient rooms reduce HAIs by 50%)
4. Implement design interventions
5. Measure outcomes post-occupancy (minimum 12-month data collection)

Key Evidence-Based Guidelines:

• Single-patient rooms: 30-50% reduction in hospital-acquired infections (Ulrich et al., 2008)
• Same-handed room layouts: 30% reduction in medical errors (standardized positions for equipment, gases, nurse server)
• Decentralized nursing stations: reduce walking distance by 40-60% (target < 8,000 steps/shift)
• Access to daylight: 2.6 fewer days of hospitalization for patients with window views (Beauchemin & Hays, 1996)
• Noise reduction: single-patient rooms + sound-absorbing ceiling tiles (NRC > 0.90) reduce ambient noise from 72 dB to 48 dB

Section 3: Compositional Principles

3.1 Proportion Systems

The Golden Ratio (Phi = 1.618...)

• Rectangle proportions: 1:1.618
• Fibonacci sequence approximation: 1, 1, 2, 3, 5, 8, 13, 21, 34...
• Application: facade divisions, window proportions, plan organization
• Historical use: Parthenon stylobate (69.5 m x 30.9 m, ratio ~2.25:1, refined by curvature), Notre-Dame facade

Le Corbusier's Modulor (1948)

• Two interlocking Fibonacci series based on human dimensions
• Red series (based on navel height 1.08 m): 27, 43, 70, 113, 183, 296 cm
• Blue series (based on raised-hand height 2.26 m): 33, 53, 86, 140, 226, 366 cm
• Applied at Unite d'Habitation, Marseille (1952): apartment dimensions 3.66 m floor-to-floor, 2.26 m ceiling height within duplex, 4.80 m facade module

Ken Module (Japanese)

• Based on tatami mat: 910 mm x 1,820 mm (3 shaku x 6 shaku)
• Half-ken (910 mm) is the fundamental column spacing
• Room sizes expressed in mat count: 4.5-mat (7.4 m2), 6-mat (9.9 m2), 8-mat (13.2 m2)
• Katsura Imperial Villa (1663): entire plan on ken grid with 10 mm tolerance

Classical Orders

• Doric: column height = 4-6x lower diameter; intercolumniation = 2.25 diameters (eustyle per Vitruvius)
• Ionic: column height = 8-9x lower diameter; volute capitals
• Corinthian: column height = 10x lower diameter; acanthus leaf capitals
• Proportional system governs entablature (architrave:frieze:cornice typically 1:1:0.75 of column height)

Palladian Ratios

• Seven preferred room shapes from "Four Books of Architecture" (1570):
  • Circle, square (1:1), sqrt(2) rectangle (1:1.414), 3:4, 2:3, 3:5, 1:2
• Villa Rotonda: 30.5 m x 30.5 m plan, 6 m x 6 m central rotunda, porticos 5.5 m deep

3.2 Balance

Symmetry: Bilateral symmetry along one or more axes. Creates formality, monumentality, institutional character. Palazzo Farnese (Sangallo/Michelangelo, 1534), National Gallery of Art East Building (Pei, 1978 — triangular symmetry).

Asymmetry: Dynamic equilibrium through visual weight distribution. Requires more sophisticated compositional skill. Barcelona Pavilion (Mies, 1929) — offset planes, pinwheel arrangement. Fallingwater (Wright, 1935) — cantilevered trays balanced around vertical stone core.

Radial Balance: Elements radiating from a central point. Pantheon, Rome (126 CE) — 43.3 m diameter coffered dome. Guggenheim Museum, New York (Wright, 1959) — helical ramp around central void.

3.3 Rhythm

Repetition: Regular intervals of identical elements. Colosseum, Rome — 80 arched bays. Lake Shore Drive Apartments (Mies, 1951) — 5.3 m I-beam mullion spacing on 21-story curtain wall.

Alternation: Two or more elements in regular alternating pattern. ABAB or ABCABC. Doge's Palace, Venice — alternating pointed arches and quatrefoil tracery. Salk Institute (Kahn, 1965) — alternating study towers and open courts.

Progression: Gradual change in size, spacing, or intensity. Jean-Marie Tjibaou Cultural Centre (Piano, 1998) — ten cases increasing in height from 20 m to 28 m. The Broad (Diller Scofidio + Renfro, 2015) — veil perforations varying from dense to open.

3.4 Hierarchy

By Scale: The most important element is largest. Cathedral nave vs. side aisles (Notre-Dame: nave 12.5 m wide, aisles 5.5 m). Civic buildings raised on plinth above surrounding fabric.

By Position: Central position implies primacy. Domed crossing in cruciform church plans. CEO office at building terminus in corporate layouts.

By Contrast: Differentiation in material, form, or detail signals importance. Entrance portal distinguished from repetitive facade (Ronchamp chapel — south wall thick, north wall thin). Lobby double-height within a repetitive office floor plate.

3.5 Unity

Material Unity: Consistent material palette (typically 2-3 primary materials). Therme Vals: Vals quartzite + water + concrete. Exeter Library (Kahn, 1972): brick exterior, concrete interior, teak furnishings.

Geometric Unity: Derived from a single geometric system. Islamic architecture: octagonal geometry generating plan, section, and ornament. Alhambra: muqarnas, tile patterns, and courtyard proportions from shared geometric basis.

Formal Unity: All parts contribute to a coherent whole. Sydney Opera House (Utzon, 1973): all shells derived from a single sphere of 75 m radius (the "spherical solution" of 1961).

Section 4: Precedent Analysis Method

4.1 Seven-Step Methodology

A structured approach to extracting transferable design knowledge from built works.

Step 1: Identify the Design Problem

• Define the specific design challenge you are investigating
• Frame it as a question: "How can a museum mediate between monumental civic presence and intimate gallery experience?"
• Narrow the scope: site strategy, spatial sequence, structural expression, envelope performance, etc.

Step 2: Select Relevant Precedents (3-5 buildings)

• Criteria for selection: similar program, similar site condition, similar climate, similar cultural context, or similar design ambition
• Include at least one historical and one contemporary example
• Include at least one from a different cultural context to avoid parochialism
• Document: architect, location, date, area (GFA), cost (if available), client

Step 3: Site and Context Analysis

• Urban context: plot ratio, height datum, streetwall condition, surrounding uses
• Topography: slope gradient, elevation change, relationship to landscape
• Climate: latitude, annual temperature range, prevailing winds, rainfall, solar geometry
• Cultural context: building traditions, material availability, regulatory framework
• Access and circulation: vehicular, pedestrian, public transport proximity

Step 4: Program and Spatial Organization

• Area schedule: list all major spaces with their areas (m2)
• Adjacency requirements: which spaces must be proximate, which must be separated
• Circulation type: single-loaded corridor, double-loaded, gallery, atrium, open plan
• Public-to-private gradient: map the transition from most public to most private space
• Vertical organization: what's on the ground floor (public) vs. upper floors (private)

Step 5: Structural and Material Logic

• Structural system: load-bearing masonry, steel frame, RC frame, timber frame, hybrid
• Span dimensions: column-to-column, clear spans for large spaces
• Material palette: primary structure, secondary structure, envelope, interior finishes
• Construction method: in-situ, precast, prefabricated, hybrid
• Detail resolution: how structure meets envelope, how materials join

Step 6: Environmental Strategy

• Passive strategies: orientation, natural ventilation, thermal mass, shading
• Active systems: HVAC type, energy source, renewable energy integration
• Daylighting: window-to-wall ratio, roof lights, light shelves, light wells
• Water management: rainwater harvesting, greywater recycling
• Measured performance: EUI (if available), post-occupancy thermal comfort data

Step 7: Synthesis of Transferable Principles

• Identify 3-5 key design principles that can be abstracted from the precedent
• State each principle as a transferable rule: "When [condition], then [strategy], because [reason]"
• Evaluate which principles apply to your current design problem
• Document limitations: what does NOT transfer (climate, budget, scale, culture)

Section 5: Design Critique Framework

5.1 Eight-Dimension Evaluation

A structured method for evaluating architectural proposals. Each dimension is scored 1-5 (1 = deficient, 3 = competent, 5 = exceptional) with written justification.

Dimension 1: Spatial Quality

• Does the building create memorable spatial experiences?
• Is there a clear spatial sequence from arrival to primary space?
• Are there moments of compression and expansion?
• Is daylight used as a spatial material?
• Benchmark: Therme Vals (spatial procession from dark entry to light bath hall), Salk Institute (compressed lab corridor to expansive court)

Dimension 2: Tectonic Expression

• Is the structural system legible and expressive?
• Do structure and form reinforce each other?
• Are connections and joints detailed with care?
• Is there a clear hierarchy of primary, secondary, and tertiary structure?
• Benchmark: Sendai Mediatheque (Ito, 2001) — 13 tube-columns supporting 7 steel plates, structure as spatial generator

Dimension 3: Environmental Response

• Does the building respond intelligently to climate?
• Are passive strategies deployed before active systems?
• Is the building oriented for optimal solar access and wind protection?
• What is the projected or measured EUI?
• Benchmark: Manitoba Hydro Place (KPMB, 2009) — double-skin curtain wall, solar chimney, 60% energy reduction vs. code baseline, 85 kBtu/ft2/yr

Dimension 4: Programmatic Resolution

• Are all programmatic requirements met?
• Are adjacencies logical and efficient?
• Is there appropriate flexibility for future adaptation?
• Is circulation efficient (target: 15-25% of GFA for institutional buildings)?
• Benchmark: Seattle Central Library (OMA/LMN, 2004) — program sorted into 5 stable platforms and 4 unstable in-between zones

Dimension 5: Contextual Fit

• Does the building respond to its urban or landscape context?
• Is the streetwall condition respected or intentionally challenged?
• Does the building contribute to the public realm?
• Are setbacks, heights, and massing contextually appropriate?
• Benchmark: Kolumba Museum, Cologne (Zumthor, 2007) — new structure built atop Gothic ruin fragments, custom grey brick matching stone datum

Dimension 6: Material Palette

• Is the material selection coherent and limited (2-4 primary materials)?
• Are materials appropriate to their structural and environmental roles?
• Do materials age well (patina, weathering)?
• Are materials sourced responsibly (FSC timber, recycled content)?
• Benchmark: Castelvecchio Museum renovation (Scarpa, 1973) — steel, concrete, stone, plaster — each material with distinct tectonic role

Dimension 7: Structural Clarity

• Is the structural system efficient for the spans required?
• Is the load path clear and logical?
• Are lateral systems (bracing, shear walls, cores) integrated into the architectural concept?
• Is the structure buildable with available local skills and equipment?
• Benchmark: CCTV Headquarters, Beijing (OMA/Arup, 2012) — continuous tube structure, 234 m tall, diagrid density varies with structural demand

Dimension 8: User Experience

• Is wayfinding intuitive (can a first-time visitor navigate without signage)?
• Are thermal, acoustic, and visual comfort conditions met?
• Is the building accessible (beyond code minimum — truly inclusive)?
• Does the building create a sense of belonging and wellbeing?
• Benchmark: Maggie's Centres (various architects) — domestic scale, garden access, central kitchen/table, no institutional corridors

5.2 Critique Protocol

1. Silent observation (10 minutes): Review all drawings and images without comment
2. Descriptive phase (5 minutes): Describe what you see objectively — no judgment
3. Analytical phase (15 minutes): Score each of the 8 dimensions with justification
4. Interpretive phase (5 minutes): What is the design trying to achieve? Does it succeed on its own terms?
5. Evaluative phase (10 minutes): What are the strongest and weakest aspects? What specific changes would improve the weakest dimensions?
6. Summary (5 minutes): 3 strengths, 3 areas for development, 1 overarching recommendation

5.3 Common Critique Pitfalls to Avoid

• Style bias: Evaluating a building because you dislike its stylistic language rather than its performance
• Image vs. experience: Judging from photographs rather than spatial experience (plan and section analysis mitigates this)
• Program amnesia: Critiquing form without understanding what the building needs to do
• Context ignorance: Critiquing without knowledge of site, climate, budget, and regulatory constraints
• Detail blindness: Focusing only on the big gesture while ignoring how materials meet, how water drains, how light enters
• Single-metric fixation: Reducing critique to one issue (e.g., sustainability) while ignoring spatial quality or tectonic expression
