We got ours from 'The Bike Shed Company'. Really nice wooden bike shed, we did not like the look of the metal ones, thought it would look like a massive tin can in the garden! Good thing about the wooden sheds is that you can also have them made to bespoke size if you need something a bit different. We got a 'pedalbase 3' which fits 3 adult bikes and it looks great in the front garden. Super secure too, our next door neighbour had 2 bikes stolen from her bike shed recently (think she got from argos or B&Q or something) - they didn't even try with us though!
