Sharp crisp shadows provides me with endless joy but they are unreliable in the UK. It makes sense that clever sun shading opportunities are more likely to come from hotter climates.
It would be hard to justify a permanent sun shelter to most UK clients. So perhaps where the sun is on a lower angle (ie the UK) the design opportunity for shadows would be with the garden walls where art can be located on the vertical plane.
When I visited Melbourne in 2008 there was a new landscape feature that stood out: sun shading facilities.
Shade sails had begun populating most school play grounds and private gardens. Sun was enemy number one.
My brother could not even enjoy his rooftop garden because the sun is too strong. He and his body corporate were busy negotiating which sun blocking technique was the best.
When he asked me what I thought about this conundrum this was my pictorial response.
