# Generate a complete apartment concept from a natural-language brief

| `3DARCH-FT-26` | [3DARCH-EP-7 — Generate a Furnished 3D Apartment from a Brief](../../3darch-ep-7.md) | `IN_BACKLOG` | `EXACT` | 3D Architecture Wizzard team | No |

## Description

Enable a person to describe residential needs in ordinary language and receive a saved 3D apartment with inferred requirements, connected rooms, openings, furniture, and lighting.

## User or operator problem

A residential user needs to translate an ordinary-language brief into a coherent furnished 3D concept without manual modelling.

## Expected value

Produces the Epic’s primary saved artifact: a connected, furnished, and lit apartment scene.

## Scope

Includes prompt validation, requirement inference, connected rooms/openings, furnishing, lighting, final persistence, and stable project identity.

### Exclusions

- Office, retail, and factory generation, export, and loading scenes into Nebula are excluded.

## Acceptance outcomes

- [ ] The service rejects empty, too-short, or oversized briefs before generation.
- [ ] Missing residential needs can be inferred and represented in the generated requirements.
- [ ] The floor plan contains connected rooms, circulation, doors, exterior windows, and dimensions.
- [ ] Furniture reflects room purpose and available space.
- [ ] Ambient, sunlight, and room lighting complete the scene.
- [ ] Completion returns a stable project identity and persists the final scene.

## Dependencies

- [3DARCH-FT-8 — Package, deploy, and health-check workplace services](../../3darch-ep-1/features/3darch-ft-8.md)

## Risks

- Generated YAML lacks complete schema, bounds, clearance, and overlap validation.

## Human approval

Linas approved this Feature for documentation on 2026-09-02T10:40:43.220Z. It is **not Approved for Solution** and has no implementation approval.

## Delivery status evidence

The Feature was separately registered at `IN_BACKLOG` as an accepted catalogue boundary. This records backlog retention, not design or delivery progress.

- Event: Catalogue registration
- Actor and authority: Linas — Human project team member
- Reason: The Feature catalogue was accepted for governed documentation and retained in the backlog.
- [Status evidence](https://discord.com/channels/1518726359512387766/1543925247361814568/1544658325738885201)

## Architecture traceability

- Requirements: none derived.
- Readiness: Not started.

Architecture solution work must not begin until a separate human **Approved for Solution** decision is recorded.
