Define an outdoor room and provide support for climbing plants by constructing an impressive timber feature.
Courtyards invite us outside in the warmer months but provide little protection from the sun.
For this exposed courtyard, a solid 6 x 2.4m timber pergola was built as a framework for climbing plants to shade the area, and supported by a ledger secured with Dynabolts to the rendered side wall of the house.
Before starting the build, ensure timber sizes meet national standards and check whether council approval or building plans are required.
We used Woodhouse Weatherproof Pink Primed LOSP Architectural Pine.
Treated to an H3 level to be termite and fungal resistant, it needs finishing with two coats of paint. The posts and beams are GL8 laminated pine, while the rafters, ledger, battens and braces were cut from structural F7 pine.
Prepare the site using stringlines to set out a 6 x 2.4m rectangle.
Check the area for square with a builder’s square and take diagonal measurements between corners.
Mark the positions of the footing holes and excavate the holes to the required size then fill with concrete.
INSTALL three 135 x 135mm posts secured to concrete footings on galvanised supports and attach a ledger to the side of the house.
ADD a roof by bolting front and side beams to the posts and ledger.
SECURE rafters set at a 5º angle between the ledger and front beam.
TOP the rafters with six equally spaced battens for lateral stability, set parallel to the front beam.
BRACE the structure with knee braces positioned parallel to the house wall off the corner posts. Footing sizes vary with soil type and wind ratings. In high-wind areas, specific post supports that must be anchored in the concrete footings are needed, so check all requirements with your local building authority.
