Check height
Allow for roof rails, tailgates, vans and any sloping driveway approach.
Manage rainwater
Plan gutter and downpipe positions so water does not discharge across the driveway or towards the house.

Common questions
How wide should a single carport be?
About 3m is a common minimum starting point, but 3.3–3.5m is more comfortable beside a wall or for a larger vehicle.
Do I need planning permission for a carport?
It depends on the property, position, dimensions and restrictions. Check current official guidance and ask the local planning authority if uncertain.
