Architectural Programme Brief
Clients brief in rooms and adjectives; buildings are designed from areas, adjacencies and constraints. The gap between the two is where scope creep lives. This converts the conversation into a schedule you can design against, tests the budget against the areas before anyone draws anything, and writes down what the project is not — the single most valuable page in any brief.
What This Skill Produces
- An accommodation schedule — every space with its area, occupancy, and the activity it must support
- Adjacency and circulation requirements — what must be near what, what must never be, and the routes between
- Site and statutory constraints — planning context, access, orientation, services, and known designations
- Performance requirements — servicing, acoustics, daylight, accessibility, and environmental targets, stated as requirements rather than aspirations
- The budget and programme reality check — the area total against the budget at a realistic rate, before design begins
- Explicit exclusions — what this project is not doing, agreed and written down
Required Inputs
Ask for these if not provided:
- The client and the driver — who they are, and what problem the building is supposed to solve
- The activities — what will actually happen in the building, by whom, and when
- The site — location, area, existing structures, access, orientation, and any known designations or constraints
- The budget and programme — the number they have and the date they need it, however soft
- The fixed points — anything already decided, promised, or non-negotiable
Framework: Activities Before Rooms, Areas Before Budget
- Brief the activity, not the room. 'A place for forty people to eat that empties in twenty minutes' designs better than 'a canteen'. Rooms are a solution; activities are the requirement.
- Put an area against everything. An unpriced schedule is a wish list. Areas are what make the budget conversation possible.
- Test the budget early and bluntly. Total area at a realistic rate per square metre, against the stated budget. If it does not work, say so in the brief rather than discovering it at tender.
- Map adjacencies as a matrix. Must-be-near, must-not-be-near, and the routes people take between them. This is where the plan actually comes from.
- Name constraints before they become surprises. Planning context, rights of light, access, ground conditions, services capacity, listed status.
- Write the exclusions down and get them agreed. The scope you did not include is only excluded if it is on paper.

Quality Checks
Anti-Patterns
- Briefing in room names. Locks in a solution before the requirement is understood.
- A schedule with no areas. Guarantees the budget conversation happens after the design.
- Deferring the budget test. The gap does not shrink by being discovered later; it just costs more to fix.
- Aspirations written as requirements. 'Sustainable' is not a requirement; a target rating is.
- No exclusions page. Every undocumented exclusion becomes a variation.
- Accepting a programme without testing it. Consent periods are not negotiable by optimism.
Example Trigger Phrases
- "Write an architectural brief for a new community building"
- "Help me capture what the client actually needs"
- "Turn these client notes into a project brief"
- "Does this budget work for the accommodation they are asking for?"
- "Write a brief for a house extension"
1---2name: architectural-programme-brief3description: Turn a client's wishes into an architectural brief that can actually be designed against — the accommodation schedule, the adjacencies, the budget reality, and the constraints named before they become change orders. Use when asked to write an architectural brief, prepare a project brief for a building, run a client briefing, or capture requirements for a new build or refurbishment. Produces the accommodation schedule with areas, the adjacency and circulation requirements, the site and statutory constraints, the budget and programme reality check, and the explicit exclusions.4---5

72- [ ] Adjacencies are recorded as requirements, not left to the plan
73- [ ] Statutory and site constraints are named rather than assumed away
