Down is the new up. In a city where space is a scarce resource one solution is to dig deep.

Stunning London Basement Design & Built

London: 8 million people squeezed into just over 600 square miles – no wonder it can sometimes feel cramped. With very little space to extend outwards and restrictions on extending upwards, if you love your home too much to move but need the extra floor space it may be time to consider a basement conversion. We’re not going to lie, a basement conversion in London can be costly and time-consuming to construct, however, the end results can be magnificent. From a small wine cellar maintained at the perfect temperature and lined with floor to ceiling racks to an entire additional storey styled from floor to ceiling to be every bit as stunning as the home above, and everything in-between, our team have designed and built them all.

CELLAR

Whether you have a few bottles you’re proud of or an entire collection, a wine cellar at home is a popular reason for a downwards extension.

End-to-End Basement Contractors

Construction techniques have moved on a very long way from the cold, dim underground rooms people used to call basements. Today a basement conversion is a light, spacious extension to your family home. With lightwells and LED lighting, you control the illumination. Advanced sound proofing means you can enjoy your cinema room’s new speakers to their full without disturbing others in your home. Modern tech in cabling, broadband and mobile signal boosters can mean your new home office is always business ready. You could create a spacious lounge or a playroom, an expansive kitchen/dining room or a new bedroom or two with en suites. Whatever you wish a basement company to create for you, we will be there from design to completion to guide, advise, support, give ideas and build your dream basement conversion.
