Design & site
The full commission, from sketch to handover: drawings, contractor consultation, then site meetings. Renovation asks more work than new build — the existing always has something in store.
Design & site
When the project goes all the way: drawings, tendering, then site meetings through to handover. Renovation costs more than new build — the existing always has something in store.
Full commission
From sketch to handover, new build or renovation.
Specifications, cost breakdown, contractor consultation.
Meetings, minutes, payment approvals, handover.
An opinion, a check, a short study, charged by the hour.
A load-bearing wall you want to open, a floor that sags, a cellar taking water, a crack that worries: in an older building these questions almost always come up, and they come up early. Five years in practice on older Parisian buildings, alongside structural engineers — underpinning, shoring, rebuilt floors — taught one simple thing: nothing is decided from memory. You survey what exists, you check, you draw the variant, and only then do you price it. Slower at the start, far cheaper at the end.
Kelliane Guerin holds the French State architecture diploma (architecte D.E., ENSA Lyon) and is not on the Order’s register. Private individuals building for themselves must engage a registered architect once the whole exceeds 150 m² of floor area or footprint — the total after works, not the extension alone. A company must engage one whatever the area. Below that, nothing stands in the way; above it, the project is carried by a registered architect as its author, and the studio works alongside them. Better said here than discovered at lodging.
