Design your house.
Cost every bag of cement.
2D plan, 3D view, quantity takeoff and cost estimate in one tool. Draw it, check compliance, get the bill of quantities — fully offline.
Building without a plan is building at a loss.
Budgets that blow up
With no reliable takeoff, you order by guesswork. Excess cement, steel and blocks add up to millions.
Rough sketches
A paper sketch reveals neither the load-bearing walls, nor opening clashes, nor compliance.
Opaque quotes
It's hard to negotiate a quote you can't verify. You deserve to see every quantity.
Everything you need to design and cost.
Built for the reality of construction in Africa — from local materials to real building codes.
Smart 2D plan
Walls, partitions, doors, windows, fences and gates. Named rooms, areas computed live.
3D view & walkthrough
Go from plan to volume in one click. Immersive walkthrough, realistic shading and to-scale measurements.
Automatic estimate & takeoff
The bill of quantities computes itself: blocks, cement, steel, sand, gravel — line by line.
Built-in compliance
Every plan is checked against real codes (SANS 10400, NF DTU), with one-click auto-fixes where possible.
BIM / IFC export
Export to IFC, the open BIM standard — interoperable with Revit, ArchiCAD and engineering offices.
Auto services & roof
Electrical, plumbing and roof placed automatically, plus door, window and room schedules.
Site photos & notes
Snap photos and add notes pinned to the plan or a room. Perfect for tracking progress and clearing up doubts.
Multi-device sync
Sign in (email or phone, no password) to find your projects on every device. Optional and free.
Offline first
Design and cost with no network and no account. The app installs and starts instantly; sync stays optional.
22 house templates, ready to draw.
From studio to villa — typologies designed for the African context. Open, adjust, cost.
+ T2, T3, T4, duplex, bungalow, patio, solar villa, townhouse, two-flat…
A plan that's verified, not just drawn.
SangoImmo ships with a rule engine that checks your design continuously: door widths, ceiling height, wet-room ventilation, stair landings, natural light…
Checks are grounded in real building codes — <b>SANS 10400</b> (South Africa) and <b>NF DTU</b> (France) — and offer a one-click fix when possible.
