free standing lumber carport project This single carport is 6000mm (20ft) long by 3000mm (10ft) wide. It is the most basic of carports.
Because each site is different, and individual preferences vary, we have given options for post installation and options for bracing.

The frame is made of wood. The roof has a minimal fall. The roof cover can be plastic PVC, tin or other metal. Choice of roof cover could well be decided by the type of conditions that the carport is likely to confront.

These plans make no allowances for extreme conditions.
Is your area subject to frosts? Find out the depth of the frost line and if applicable check to see if the footings require any special consideration. Usually the bottom of the footings should be below the frost line to prevent movement.

Check with your Local Authority to see what plans, permits, consents etc may be required to erect such a structure.

Wood sizes and measurements

The measurements throughout this project are given in both Metric (mm) and Standard/Imperial inches.
The metric measurements (mm) are given first followed by the imperial measurements (inch) in brackets (). For example 150mm x 50mm (2" x 6").
In the above example 150mm x 50mm means wood that is 150 millimeters wide by 50 millimeters thick.
And the equivalent in standard...
2" x 6" means wood that is 2 inches thick by 6 inches wide.

The wood used for this project can be either sawn (rough sawn) or dressed (gauged, surfaced, smooth finish). The measurements given throughout this project are for sawn wood.
If dressed wood is preferred, make allowances for the difference in wood thickness and width.

Use a wood suitable for in-ground applications for the posts and use a wood suitable for exterior applications for the rest of the carport structure. Any lumber merchant or supplier will be able to advise on the types of wood most suitable.
