Have you considered a basement conversion if you're in need of more space? Converting a basement has become increasingly popular in recent times for those looking to improve and not move, extending down to create a basement storey beneath their existing property. 

The new floor space it adds to your home can be used for a variety of purposes — unlike a loft conversion, which better lends itself to creating additional bedrooms, a basement is near to the main living spaces, so can be used as a social space too.
