Building an AI Assisted Office to Housing Feasibility Workflow

When I evaluate an empty office building for housing, I treat the first model like an untrusted prototype. It is useful for generating questions, but it is not a source of truth. The workflow below keeps the visual speed of AI while separating it from the measurements, code decisions, and professional sign-off needed for a real conversion.

1. Define the Conversion Targets I begin with three named scenarios: residential, shared work, and community use. Each scenario gets a short program: unit count and mix, shared rooms, ground-floor uses, service spaces, and target users. Naming the options prevents a discussion from drifting between an apartment plan and a coworking plan without noticing. I also record constraints before any image generation: floor-to-floor height, structural grid, window spacing, existing shafts, stair locations, elevator dimensions, loading access, and known zoning limits. Missing data is written down rather than filled with a plausible-looking guess.

1. Create a Site Context Layer For a quick urban read, I select the relevant block on a map and use Shapezo to generate an initial 3D model of the area. The model gives me a shared view of neighboring heights, streets, open space, transit edges, and the office building's relationship to the public realm. I record the selection boundary, date, and data sources so another person can understand what the model includes. The output stays in the context category. It is not a survey, a geotechnical base, a BIM deliverable, or a legal description of a parcel. A surveyor still verifies property lines and grades. Civil and utility teams verify easements, connections, and stormwater conditions.
2. Generate Comparable Options I ask the model for the same camera and the same building shell across three uses. For housing, the prompt focuses on daylight zones, varied unit types, shared circulation, and a visible accessible entrance. For shared work, it focuses on flexible floor plates, acoustic rooms, and meeting areas. For community use, it focuses on a clinic, classrooms, a library room, and public circulation. Keeping the shell and view stable makes the comparison more useful. I do not let each image invent a different tower. The images are still concept studies, so I attach a status field: concept, effect, or scheme. I also store the prompt, model name, date, and reference materials.

1. Run Geometry and Code Checks Before a preferred option moves forward, I run a manual review list. Daylight and Depth Map the usable perimeter and identify rooms that sit too far from windows. Test courtyards or light wells without assuming they are free of structure or waterproofing problems. Circulation and Egress Trace accessible routes from sidewalk to unit, shared room, and exit. Trace both exits from every occupied area. Check travel distance, stair continuity, corridor width, door swings, elevator access, and fire department approach. Structure and Services Confirm the load path from roof to foundation. Locate columns, transfer conditions, shafts, risers, electrical rooms, trash, deliveries, and mechanical equipment. Verify floor vibration and acoustic separation where homes replace offices. Envelope and Comfort Test window replacement, insulation, shading, ventilation, moisture control, and energy performance. A preserved facade may need substantial upgrades to work as housing.
2. Assign Human Owners The architect owns program coordination and the design record. The structural engineer confirms loads and existing frame capacity. Mechanical, electrical, and civil engineers own their systems. A code and accessibility reviewer checks local amendments, fair-housing obligations, and public access. Each open issue gets a named owner and a due date.
3. Keep the Evidence With the Image I keep a provenance log for every retained output, including model, prompt, source data, reference images, permissions, edits, and intended use. I do not place confidential client drawings into a service without authorization. If an image enters a public meeting deck, the note says whether it is illustrative or measured.
4. Freeze the Permit Set At submission, exploratory geometry is removed from the authoritative set or replaced with checked drawings. The final package should show who verified the floor plan, fire strategy, structure, envelope, and accessibility. AI can reduce the time spent making alternatives. It cannot carry a license, answer a correction notice, or make an unsafe stair acceptable. I keep one more check in the log: operations. A residential building has different trash pickup, deliveries, maintenance hours, security needs, and acoustic expectations than an office. Those practical changes can affect the lobby, loading bay, and service corridors just as much as the apartment layout does.
