Around 60% of the UK population live in semi-detached houses* so it really should come as no surprise that extending a semi is one of the most popular projects undertaken by homeowners, keen to make the most of their properties. 

Semi-detached houses have so much going for them when it comes to building an extension, particularly when compared to terraced houses, yet often their full potential isn't reached.
