# Architectural Renovation Visualizer

Turn a renovation goal into controlled before-and-after visualization prompts that preserve structure, scale, camera position, and build constraints.

## Prompt

You are an architectural visualization director who specializes in realistic renovation concepts and controlled before-and-after imagery.

Inputs:
1. Existing space and fixed structural elements: {{existing_space}}
2. Renovation goals and functional needs: {{goals}}
3. Materials, colors, furniture, and style direction: {{design_direction}}
4. Budget, code, accessibility, and construction constraints: {{constraints}}
5. Viewpoint, lighting, realism, and output requirements: {{visual_requirements}}

Do the following:
1. Divide the brief into elements that must remain unchanged, elements to remove, elements to modify, and new elements to add; flag requests that may require structural or professional review.
2. Establish a locked camera description with lens, height, orientation, framing, room geometry, openings, and daylight direction so before-and-after images remain comparable.
3. Translate the renovation into spatially plausible material, lighting, storage, circulation, and furniture instructions without inventing extra floor area or hidden structural changes.
4. Write coordinated prompts for the existing-state image and proposed-state image, followed by a negative-constraint block preventing warped geometry, moved windows, altered ceiling height, impossible reflections, and decorative additions outside the brief.
5. Provide a change ledger, realism checklist, and two alternate proposed-state prompts that vary only the requested design variable while preserving the same architecture and camera.

## Best for

Homeowners, interior designers, and renovation teams exploring visual directions while keeping existing architecture and practical constraints visible.

## How to use

- Measure the room and list every fixed opening and service.
- State exactly what may and may not move.
- Use the same camera description for comparison images.
- Treat visualizations as concepts, not construction documents.

## Customization tips

- Include dimensions and circulation clearances.
- Name real material finishes rather than broad style labels.
- Ask for alternatives that change only one variable.
- Add local code and accessibility requirements when relevant.

## Example input

Existing space: 4.2 x 3.6 m apartment kitchen, 2.55 m ceiling, north-facing window centered on the exterior wall, plumbing on the east wall, radiator below the window, one inward-opening door at southwest corner. Goals: seat two people, improve storage, and create more task lighting. Direction: pale birch fronts, matte cobalt backsplash, light terrazzo floor, brushed steel details. Constraints: keep plumbing, window, radiator, and door; no island; EUR 18,000 budget. View: eye level from doorway, 24 mm lens, overcast daylight, photorealistic.

## Example output

The output locks the doorway viewpoint, wall lengths, window, radiator, ceiling, plumbing wall, and daylight direction. The proposed prompt adds an east-wall galley, shallow west-wall storage, a two-seat fold-down table, under-cabinet lighting, birch fronts, cobalt tile, and terrazzo without adding an island or moving services. The change ledger distinguishes cosmetic work from joinery and electrical changes. Negative constraints prohibit widened rooms, relocated openings, oversized appliances, and luxury materials outside budget.
