Interior architects in France designing offices for banks, law firms and consulting groups are leaving money on the table.
Core trick
A chat agent edits the live floor-plan model through tool calls, then regenerates the 3D test-fit and dimensioned DXF from that model.
Description
Interior architects in France designing offices for banks, law firms and consulting groups are leaving money on the table. Each one handles only one or two clients a month — not because the demand isn't there, but because they spend 60 % of their time on iterations a software should do for them : drawing in AutoCAD, rendering in SketchUp, checking French codes manually, building mood boards in Photoshop, for every variant, every iteration, every client meeting. So when a fifth qualified prospect calls, ready to sign, they get added to a waiting list. Or lost.
Archoff is the quiet co-architect that takes back those weeks. From a single client brief, it produces a sourced functional programme, three 3D test-fit variants pushed live into SketchUp, a curated mood board sourced from real catalogues like Vitra and Herman Miller, a sourced argumentaire backed by neuroscience research and French regulation, an 18-slide magazine-grade client presentation, and a dimensioned DXF dropped straight into AutoCAD for the engineering hand-off. The architect refines through a chat that doesn't just answer — it acts : add a zone, move a wall, regenerate a variant.
What used to take six weeks now takes minutes. The architect can finally answer the fifth call.
