ProtoHaus for Contractors
Start projects aligned, not revised
Early planning is where jobs stay on track. ProtoHaus helps you map a client's vision into a clear starting layout, spot issues early, and align fast before plans, bids, and revisions start stacking up.
Reduce Change Orders by 60%
Most projects face 3–5 major revisions after breaking ground. ProtoHaus locks in layouts before construction starts, cutting costly mid-project changes that drain your profit margins.
Cut Pre-Construction Time in Half
The average project spends 4–6 weeks in the planning phase with back-and-forth revisions. Get client sign-off on layouts in days, not months.
Get Instant Cost Estimates with Every Layout
ProtoHaus automatically calculates project costs based on floor plan requirements. Quote accurately in minutes, not days—and protect your margins from the start.
How It Works

Your client answers simple questions about their dream home—square footage, rooms, priorities, and style.
