L-shaped patios, back-of-house layouts where the garden turns a corner at ninety degrees, outdoor spaces that connect a dining area to a seating area, and configurations where the boundary meets the house at a right angle and coverage is needed along both runs.

The corner post is the structural anchor — a single post at the corner junction from which both arms of the structure extend at ninety degrees. The overhead rails and rafters run from the corner post outward along each arm. The corner post carries load from both directions and is fixed accordingly.

Bolt-down feet for hard surfaces and spike anchors for soft ground or grass. The choice is made at the point of order and affects the price. Both methods fix the corner post and the outer posts securely.

A standard polycarbonate roof kit fits a rectangular span. The corner configuration makes a single roof kit across both arms impractical — the two arms each need independent roofing. This is possible but requires planning at the design stage. Ask about the roofing options for corner structures when ordering.

It requires more care with setting out — getting the corner post positioned correctly before fixing is important, as both arms of the structure depend on it. Two people with a drill, a level and spanners, with a third pair of hands useful for the corner post setting stage.
