  "description": "Build a 3D model of a three-storey neoclassical colonial building with arcaded verandas and pediments. Use the supplied dimensioned diagrams as the geometric reference: diagram_01.png, diagram_01_sheet2.png and their details (diagram_01_detail01.png to diagram_01_detail09.png). Work in millimetres at full scale.\n\nPart 1, the main building (sheet A-201):\n- Overall extents are 123053.4 mm wide (front view), 101008.3 mm deep (top view) and 45720 mm high.\n- The plan is a large rectangular block. Its perimeter walls are pierced by a regular rhythm of round-headed arched bays.\n- There are three equal storeys of about 15240 mm each.\n- Repeating round-arched openings run along every elevation on all three levels.\n- Projecting arcaded veranda blocks on the front have stacked arched loggias, floor-level cornice bands and balcony edges.\n- Tall arched multi-pane windows are set within the piers.\n- A further arcaded veranda wing sits at the corner and side.\n- An open forecourt edge runs along the front.\n\nPart 2, the single-storey pavilion (sheet A-202):\n- The pavilion is an L-shaped block with overall plan extents of 45159.6 mm by 32308.8 mm and a height of 15240 mm.\n- The front elevation has an arcade of three round arches carried on piers with impost mouldings.\n- A projecting entrance bay holds a single arched doorway.\n- A stepped plinth runs at the base.\n- A horizontal string course runs across the walls.\n- A projecting cornice and roof edge finish the top.\n- The roof is low-pitched, with hipped intersections over the L.\n\nOrganise the model professionally:\n- Make each repeated architectural element a component definition and reuse it as multiple instances rather than copying loose geometry. This applies to arched bays, window units, pier and arch modules, cornice pieces and similar elements. Use at least 20 component definitions, placed as more than 1000 instances in total.\n- Apply at least 30 named materials to distinguish surfaces such as walls, trim, roofs, glazing and floors.\n\nThe model shall be viewable as a top view, front view, right side view and isometric view matching the sheets.",
