I need a modern, practical and affordable 2-bedroom house design on a 50 × 50 ft residential plot in Nigeria. The road is at the front of the plot, with neighbours on both the left and right sides. I want the compound mainly at the front, with parking for one car. The house should have two bedrooms, with one larger master bedroom, one parlour/living room, an open-plan kitchen located close to the dining area, one indoor bathroom/WC, and one additional outdoor WC positioned on the side/service area. The design should provide good privacy, natural lighting, cross ventilation, practical circulation and easy maintenance. I prefer a simple, elegant and modern Nigerian residential style that is beautiful but budget-conscious. I want a modern flat-roof/parapet appearance from the front, with a clean façade, attractive entrance, modern windows and good exterior lighting. The roof design must properly consider rainwater drainage, waterproofing and future maintenance. Approximate room targets: parlour 14 × 13 ft, dining 9 × 8 ft, open kitchen 9 × 9 ft, master bedroom 12 × 12 ft, bedroom 2 approximately 10 × 11 ft, bathroom/WC approximately 7 × 6 ft, and outdoor WC approximately 5 × 4 ft. These are conceptual targets and should be optimized by the architect to fit the 50 × 50 ft plot, required setbacks, wall thicknesses, circulation and service spaces. Please provide a dimensioned floor plan, site/plot plan, front elevation, side/rear elevations, building sections, door and window positions, kitchen and bathroom layouts, roof/parapet concept and a professional 3D exterior rendering. The final design should be original and adapted to the site rather than simply copying a reference image. Structural elements such as foundation, beams, columns, reinforcement and concrete slab must be designed and verified by a qualified structural engineer based on actual soil conditions, calculations and local requirements.
