When much of our existing housing stock was built, lifestyles were very different. This means that a large proportion of a contemporary architect's work is about adapting these older buildings, rather than building afresh. The challenge for today's architects is thus to adapt our old buildings to our new ways of living, whilst not destroying what we like about them. This often means adding more space to the back, the roof or the side, or even sometimes underneath, whilst retaining the original building's front as part of the streetscape. Houses: Extensions brings together 15 exceptional extension projects including 8 from the UK that showcase some of the most innovative and stylish architectural solutions for adding more space to a home. UK firms featured: Adam Knibb Architects, Chris Dyson Architects, Ashton Porter Architects, Paul Archer Design, AR Design Studio, Tigg+Coll Architects, and Riach Architects.
