Renovation and extension plans
Renovations fail in the gap between what the owner pictured and what the drawings say. Generating four measured options from the existing plan closes that gap in an afternoon rather than three meetings.
Free for your first 5 plans. No card, no install.
Start from the house that exists
Upload the existing plan — a scan, a photo, a DWG — and Archi4D rebuilds it as measured geometry. Lock the rooms you are keeping and regenerate only the part you are changing, so the options you compare are all real renovations of the same house.
Find out what the extension costs you
Every option comes with an area schedule and a material board that prices into it. The trade-off between a bigger kitchen and a third bedroom becomes a number rather than an argument.
