Architecture and interior design thread

I have the chance of getting some photography work on behalf of an architecture firm. I normally do portrait and modelling stuff so have nothing to show them. Ergo I'm going to get on me bike and hit the streets and hopefully photograph things beyond the norm.

So other than the obvious stand out addresses and Googling to find buildings does anyone know of any hidden gems around central/south London ? I'm thinking both commercial and residential with a lean to the modernist and graphic style. I thought I knew London pretty well but my mind has turned to mush coming up with places.

Ideally somewhere quiet too, I really just want to shoot a building with as little going on around it as poss. Mebee the city on Sunday morning.....

All ideas welcome, could do with some sharp looking interiors too.

I own a book that came out in 1997 (Small House Designs - ISBN - 0-88266-854-4) that showed a house on Hoxton Square that I really liked, but the book only had illustrations, no photos. The one time I searched for it I had no luck. I'm in Canada, so I don't have regular opportunities to look around there. Megan Williams is the architect, so you could contact her; based on this house, she probably has continued to do innovative work.
