Building Photo to Architectural 3D Model

You are working as a 3D modelling agent with Blender open. Using the uploaded photograph of a building, reconstruct the building as editable 3D geometry and produce a presentation render. STEP 1 — Read the reference. Before modelling, state back what you measure from the photo: number of storeys, approximate floor-to-floor height, roof form, window grid and spacing, and the primary facade materials. Work in real-world metric units. If the photo is a three-quarter view, infer the hidden elevations symmetrically and say that you are inferring them. STEP 2 — Build. Model the whole building including the visible portion of its site. Geometry fidelity is the hard constraint: preserve the proportions, storey heights, window positions and roof pitch visible in the photograph. Do NOT redesign, restyle, beautify or 'improve' the building. If a detail is not visible, keep it simple rather than inventing ornament. STEP 3 — Keep it editable. Every element below must be a separate, named object — not merged into one mesh: Walls, Roof, Glazing, Window_Frames, Doors, Balconies, Ground. Apply a single material per named group. A visually convincing single-mesh shell is a failed result. STEP 4 — Materials. Match the materials visible in the photograph as closely as you can identify them — set base colour, roughness and a plausible bump or normal for each. No procedural noise standing in for real material character. STEP 5 — Scene. Ground plane with a paved forecourt with low planting beds and two street trees. Lighting: clear morning light with the sun 35 degrees above the horizon from camera left, using a sun lamp with a physically plausible angle plus a sky HDRI for fill. Camera: 24mm three-quarter view from street level, at human eye height of 1.6m, with the vertical lines of the building kept vertical — apply a two-point perspective correction rather than tilting the camera up. STEP 6 — Output. Save the .blend file, export a GLB, and render one hero frame at the highest resolution Blender is set to. COMPLETION CRITERIA — do not stop at the first render. Render the frame, look at it, and compare it against the uploaded photo. Check: storey count matches, window grid matches, roof form matches, no interpenetrating geometry, no floating elements, vertical lines vertical. Where the render diverges from the reference, revise your script and re-render. Repeat until all six checks pass, then report which checks you verified and list every named object you created.
