Pergolas have an open slatted roof allowing views of the sky. While pergolas offer some shade, it will usually be limited if the sun is directly overhead. Pergolas are great for a garden or patio and with the case of timber frame pergolas, they are a phenomenal architectural feature. One way that you can get more shade from your pergola is through the strategic use of plants that will climb the pergola and can be guided to cover all or part of the top or sides. Typically, the pergolas we do are free standing but it is possible to incorporate it into the side of a building.
Here are two renderings of potential timber frame pergolas.
The first rendering is a 16' x 8' with corner posts
The second rendering is 20' x 10'
The third rendering is 16' x 31'
