In the absence of any personal recommendations, I can only go by googling or looking on yell.com or the like, and then looking at the designer's website.
Do I go by location - ie do they have to be close to me or can I look further afield?
Do they all charge a similar amount?
Has anyone used one, and have any advice?
I have a small London garden, but all the designers' websites that do urban stuff seem to do the kind of urban that involves minimal gardening. Whereas I want to maximise the gardening in my urban setting. It is an urban garden but I don't want it to look that way.
