Welcome to BasementWorks – exceptional designer basement conversions

BasementWorks has considerable experience of basement conversions and basement extensions throughout London. We specialise in all aspects of basement work, from extending and converting existing cellars to completely new basement excavations.

At BasementWorks we deal with projects in £250k to £600k range. Larger projects and whole house refurbishments can be handled by our sister company OLBC.

We believe quality is realised through good design, organisation, efficiency and commitment right through to the end. We have built a reputation for integrity as well as quality and we will always make time to explain the detail to help you understand what you are investing in.

BasementWorks can either offer a fully bespoke or fixed price options according to our client's preferences.

BasementWorks popular, fully interior designed, packages were created in response to a growing number of clients wanting to have the complete picture of cost upfront – even down to the interior fitting and finishing of their London basement conversions. So if you are looking for a basement design at a price you can rely on, BasementWorks can offer you a range of packages covering all common requirements from bedrooms, bathrooms and utility spaces to basement cinema rooms, wine cellars and gyms*.

And because BasementWorks uses the same highly skilled workforce on our fixed-price basements as our bespoke London basement conversions, you will always benefit from the same level of craftsmanship and care.

Whatever extra spaces you need BasementWorks has a basement conversion package to suit. Contact us now for a no obligation quotation. A BasementWorks basement is so much more than your average London basement.
