The prompt
Design a two-storey (G+1) building in 2D plans and 3D views. All dimensions in metres, floor-to-floor height 3.6 m. GROUND FLOOR - Three classrooms side by side, each 6.0 m × 6.4 m (18 m total frontage). - Each classroom has a front door, a front window and a back window, 3 rows of student desks with chairs, a teacher's desk and a whiteboard on the back wall. - On the right side, outside the classroom block: a 1.2 m wide half-turn (U-shaped) stair, 2.6 m wide overall, with a mid-landing, 10 steps per flight, entered from the front. - Under the balcony, between the classrooms and the stair: a 3 m wide covered sit-out supported by three columns. - Front veranda and pavement along the classroom side. FIRST FLOOR - At the top of the stair: a small arrival landing that opens onto a 4 m × 7 m open-air balcony. - The stair stays outside the balcony, so the full balcony is free for greenery: planter beds along the back and right edges, a lawn patch, a bench, small trees and shrubs, with a 1.1 m glass railing. - Next to the balcony: a 17 m × 7 m conference room with a door onto the balcony, six large front and back windows, a long table with 20 chairs and a wall screen. ROOF - Pitched corrugated metal sheet roof over the G+1 conference room, with a ridge cap, gable ends and a small overhang (assumed for "ega roof"; replace if you mean another type). OUTPUT REQUIRED 1. 2D ground floor plan with all dimensions, door swings, windows, furniture and stair. 2. 2D first floor plan with all dimensions, the greenery layout, conference layout and stair arrival. 3. 3D exterior views (front-right and front-left) showing the roof, balcony greenery and stair. 4. 3D cutaway views of each floor with walls cut at 1.2 m. Style: realistic architectural drawing, clean line work, A3 landscape, title block, metric dimensions, soft shadows, natural materials (plaster walls, tiled floors, glass, timber).
