There's no reason at all why a garden building shouldn't have more than one function. This one was a bright summerhouse, with a traditional darkroom attached.
The end of this rather dull existing garden had a disused greenhouse, on old shed, and a WW2 concrete air raid shelter! All had to be removed, and the base area for the new building and the tiered decks had to be levelled, and new boundary fences constructed. The darkroom required water, power and waste systems, all of which had to be set in deep trenches the length of the garden.
The building was in a traditional style to be in keeping with the area. The decks stepped down the garden, giving plenty of room to sit out.
I was then asked to landscape the garden - see Photographers garden.
