A wall is a wall....isn't it?

I've been worrying of late that my designs might be getting a bit 'samey'. You see the thing is that prospective clients see photos on my website and have to like them before they give me a call, if they like the photos of other designers' gardens better then of course they will ring them instead. So I try to show a variety of garden styles, I hope I'm versatile enough to design to suit any client's tastes and this week I have returned to see two gardens I've designed over the past couple of years and I'm very relieved to see that they are not at all samey ... ... except that they both use walls ... you see they are designed for their owners who are very different people with very different tastes...
