Basement Conversions are often the only option in creating extra space in modern urban environments, but they need to be carefully planned and executed to realise their true value.

Nicholson Basements have been converting basements in London for over 16 years and so we know how to deal with the whole process, from restricted access sites and problematic soil. Almost all of our work comes through personal recommendation.

We not only have a huge amount of experience in basement and cellar conversions, but also financial stability, superb quality control, guarantees and management systems that ensure that you have complete peace of mind.

We help you through the whole process, from detailed planning and costing of the project through to any statutory issues such as planning and party walls and most importantly we take the time to analyse your requirements properly and then we work with you to produce the most effective solutions.
