01 · Before the build
Draw a house or start from a ready-made design
You draw walls, doors and windows. Rooms and their areas work themselves out, and the 3D model takes shape next to the plan.

How it works
Baukit helps before the build, during it and with the finishing.
02 · During the build
Check heights, floors and layers
Every storey has a floor level, a clear height and floor layers. On site you have those numbers at hand.
03 · Finishing
Work out the ceiling, flooring and paint to the last pack
The calculators give the number of pieces, packs or litres, with an allowance for offcuts.

You don't need to learn design software.
A free AI assistant will draw, change and calculate for you. Just write what you want.
Example question: Change the roof to a hip roof
Baukit assistantDesign change
- I'm replacing the gable roof with a hip roof pitched at 25°.
- The floor plan stays as it is; the gable walls now end at eaves height.
- The 3D model and the roof cost are recalculated.

What Baukit is for
Before you ask a builder, work it out yourself.
You usually only see a house cost estimate at the builder's or the builders' merchant. Baukit shows it to you earlier: from a floor plan you draw yourself, or from a ready-made design in the GUNB catalogue.
Every number can be checked. You see the quantity, the unit price and the waste allowance we added to it.
Start with a drawing.Baukit works out the rest.
