residential floor plan 3d model

Design a residential house floor plan on a rectangular plot 30 feet East to West (Purab to Pashchim) and 45 feet North to South (Up to Down). The layout should include four rooms, symmetrically placed around a central corridor (galiyara in the middle). A staircase should be positioned between the rooms, with the kitchen located adjacent to the staircase. Provide an outside washroom/toilet, accessible from outside the main living area. The design should ensure proper ventilation, natural light, and functional movement flow. Create a clean, modern Indian residential layout, suitable for a small family, with accurate proportions and realistic architectural detailing.
