Just tell me your budget. My conservative estimate: without corner windows, floor-to-ceiling windows, 3 bathrooms per semi-detached house, etc.
House: Standard Volume 214.2 x 4.5 + 214.2 x 5.5 x 0.5 + 2 x 4.5 x 2.0 x 2.0 * 0.5 = 1,570.95 m3 * 700 = 1,099,665 (approx. 350 m2 living space * 3,000 = 1,050,000) 2 garages x 20,000 = 40,000
2 cellars 214.2 * 3 * 300 = 192,780
Additional costs 10% 135,000
Total: 1,467,000
Do you have the 1.5 + X million?
