GuideHow to estimate a renovation from the floor plan
The floor plan is the fastest place to start a renovation estimate. A scaled drawing already contains most of what a takeoff needs — room areas, wall lengths, and counts of doors, windows, and fixtures — so you can measure off the plan instead of crawling the site with a tape. Here's how to turn a plan into a defensible number.
What you can pull straight from the plan
- Floor areas per room — for flooring, tiling, screed.
- Wall lengths & areas — for framing, plaster, and paint.
- Openings — counts of doors and windows.
- Fixtures — kitchen and bathroom items to price or coordinate.
- Room counts — to scope work room by room.
The workflow
- Confirm the scale from a known dimension. Without one, Extruda assumes a standard 0.9 m door, and sizes can be noticeably off.
- Take off quantities — areas, lengths, and counts by room.
- Apply your rates — see how to price a renovation job.
- Verify the unknowns on site (what's behind the walls, condition, access).
- Build the quote — turn quantities into a clear renovation quote.
Only have an image or PDF plan?
A photo or PDF isn't measurable geometry — but you can convert it first. Extruda turns a 2D plan into editable geometry and 3D, so you can take quantities off the drawing and even show the client the finished space. On Home and above, the takeoff sits on the Materials tab, and Studio and above lets you add it to a quote, so the takeoff and the quote can live in one place.
From plan to estimate to finished project
Extruda's Studio, Realty and Enterprise plans include renovation project management — estimate from the plan, quote, and track the job.

Can you estimate a renovation from a floor plan?
Yes. A scaled floor plan gives you room areas, wall lengths, and counts of doors, windows, and fixtures — the quantities a takeoff needs. You can measure off the plan instead of re-measuring on site, then apply your unit rates.
What quantities can I pull from a plan?
Floor and wall areas for finishes, wall lengths for framing and paint, room counts, and counts of doors, windows, and fixtures. Combined with your pricing rates, that produces a fast, defensible estimate.
How accurate is estimating from a plan?
As accurate as the plan's scale and your rates. Confirm the scale from a known dimension, verify anything unusual on site, and treat the plan takeoff as a first draft to check rather than a substitute for judgment.
What if I only have a plan image or PDF?
You can convert an image or PDF plan into measurable geometry first, then take quantities off it. Extruda turns a 2D plan into editable geometry and 3D. The takeoff is on Home and above, and Studio and above adds quoting and renovation project management.
