Much has been written about excavations to form new basements which have become increasingly popular in some areas in London. Lots of properties have existing basements and that space can be converted to add space to your house. Some basements can be successfully converted to create dry storage space. Whereas others, of a larger size and where you may be wanting to create additional living space, can be designed as such and converted accordingly. Before proceeding with such work, there are numerous factors which should be considered before deciding on conversion works.
