Great idea from oklouise, extendable awnings are great also, vergola, laser cut screens can add a stylish look and give a lovely ambience, deciduous trees are perfect, shading in summer then letting winter sun in on colder days, we planted 3 Bradford ornamental pears and it’s just perfect on hot days and very architectural in the winter, not to mention glorious colour in autumn, adds a glow to the garden.

An opening pergola is probably the most adjustable controllable choice but was quite expensive when we looked into it.

Deciduous trees/vines can be good in summer but not necessarily as useful in spring and autumn and of course create a lot of work.

Shadecloth as suggested by oklouise is great for all sorts of adjustable and DIY solutions.

How much sun do you get in winter on the southwest though, do you need to have something removable/openable?

A verandah would be a simple and relatively cost effective way of providing some protection from that heat. If you are concerned about losing valuable light into the adjacent rooms we recommend using some translucent polycarbonate sheet roofing. You can get Level 3 'heat reducing' sheets which can cut heat penetration to below 20% whilst still providing that valuable natural light that we love in outdoor spaces. See Ampelite Solasafe. Shade battens are another option although they won't keep the rain out!

Thanks, but not an option to raise the roof nor do Vergola...we are too far down the path.

Need to work with what we have :)
