See your outdoor space before you build it
AI exterior design shows what your deck, garden or facade would look like before you buy anything. Roomstill starts from a photo, keeps the building and the plot boundaries exactly as they are, and returns a result in about thirty seconds — with the cost of the materials per square metre.
Why outdoors is harder than indoors
A room has four walls and a ceiling: the frame is given. Outdoors nothing bounds the eye, which is exactly why people get it wrong. You see a deck in a catalogue photo, you order it, and once laid it looks half the size — because you had no reference. Starting from a photo of YOUR place fixes that: the proportions are yours, not the catalogue’s.
What never moves
The building and the plot. The house, its roofline, its openings, the boundary: all stay put. Someone redesigning a garden does not want their facade changed, and someone redoing a facade does not want their windows moved. The lock goes into every prompt sent to the engine, with no exception.
And the cost, which nobody else gives
Every render comes with the materials and their price per square metre. Treated pine decking runs €15-38/m², natural stone paving €30-95/m², facade paint €1-5/m². Prices are materials only, surveyed on the French market: fitting is extra, and outdoors it often costs as much as the material. Enough to know whether a project fits a budget before calling a contractor — not a replacement for their quote.

Questions people ask
Is there a free AI landscape design tool?
Free 3D planners exist, but they require you to draw your own plot, which takes hours. Roomstill starts from a photo and returns in thirty seconds; it is paid, from €7.99 for forty renders, with no subscription and no account to create.
Do I need a plan or measurements?
No. A photo of your outdoor space is enough. That is the point: the proportions come from your place, not from an approximate drawing.
