Comparing house types before you commit drafting time
Decide which plan types are worth developing before anyone bills hours drawing them.
Generate a family of types
Vary bedrooms, area and outline across one brief and compare the results on the same objective rather than on taste.
Test a type against a footprint
Set the outline and proportion; the solver fits the brief to it or tells you the room list will not go.
Keep the numbers honest
Areas are exact by construction, so a schedule built from a batch of plans adds up.
Where it stops
Feasibility support, not planning submission. Yield, zoning and code still need the professionals who sign for them.
