Build the full technical diagram plan for a cavity-wall insulation survey — every elevation drawn to scale, treatable areas and POPT calculated live, and a polished PDF with a full breakdown and a 3D model of the property. Made by surveyors, for surveyors.
Set the wall height and width, then drag windows, doors, untreatable areas, wall types and drilling points onto the to-scale grid. A worked example is loaded so you can see how it fits together.
Wall, window/door and untreatable areas total up live for every elevation, and the whole-house POPT figure updates as you draw — no spreadsheet needed.
One click produces the finished PDF: every elevation with its schedule, a full property breakdown, and a 3D model of the house assembled from your drawings.
Upload your floor plan(s) (JPG or PNG) — one image per storey is ideal. The bottom edge of the plan is the front of the house. Generate whole property builds all four elevations (Front/Rear/Left/Right) from the plan in one go; or use Just this elevation for the one selected below. Always review the counts and wall sizes before exporting.
Save the current plan to your account, then load it on any device.
