KeyMonth
House planner
Mortgage calculator

Turn your plot into a house plan

Enter the plot size, the space your local rules keep free at the edges, and the rooms you need. KeyMonth lays out every floor with doors, windows, stairs and furniture, and shows it in 3D from outside, inside each floor and inside each room. It is a concept to discuss with an architect, not a construction drawing.

    Not for construction. The layout is generated from typical room sizes. It does not check local building codes, structure, fire safety, ventilation, drainage or permits. A qualified local architect or engineer must design and approve any real building. KeyMonth is an estimate tool; it does not offer loans or professional advice.
