Basement conversions

Subterranean space adds fantastic value

Basement conversions offer a great return on investment and are often the means of bringing real additional space and luxury living to London homes. Cinema rooms, playrooms, games rooms, wine cellars, gyms, saunas, swimming pools, nanny, granny and teenage flats are just some of the ways we are seeing basements being used. 

Basement and cellar conversions

Ensoul can design a beautiful basement conversion for you either under your house or under a garden or drive that will deliver fantastic additional living space. Our basements feature incredible light from clever use of structural glass and lightwells; and a real sense of space with deep excavation to get tall ceiling heights. This is how we break the mould and enable basements designed by us to achieve pretty much the same value per square metre as your above ground space (which is not the norm).

Ensoul basement conversion services include designing and managing the entire process for you; from creating the architectural plans and submitting your planning application through to decorating, fit out and hand-over. Along this journey we will bring in and manage a team of trusted geologists, structural engineers, drainage experts, basement excavation specialists and waterproofing systems for this highly specialised piece of work.
