Design a Carport Yourself – with 3D Software in the Browser

A carport protects your car and is a great DIY timber project. The keys are the right size, sound structure and a well-thought-out plan.

Size and parking space

Plan around 2.7 × 5.0 m per car, better 3.0 × 5.5 m for comfortable access. For two cars about 6.0 m width. Mind the clearance height (at least 2.2 m).

Posts, purlins and roof

Load-bearing posts are usually 12 × 12 cm, purlins 10 × 20 cm. A flat roof needs a slight fall (3–5°) for drainage; a mono-pitch roof sheds rain in one direction. Add diagonal braces to stiffen against wind.

Plan in 3D and calculate material

In HolzBau 3D you place posts, beams and rafters to scale and get the full parts list. You know the timber demand and cost before you reach the store.
