Why Cox Format?

Cox Format Developments Limited is a professional building company specializing in extensions and loft conversions in North London. The majority of our work is through personal recommendations. We are always happy to show previous work and our customers are happy to let you look! We pride ourselves on quoting a good price and sticking to it. Unless you instruct us to, we never add on "extras" as some less reputable builders do as their standard practice.

Because we are professionals and have been operating in North London for years, we can see what work is necessary to achieve your objectives, and we price accordingly. Others may quote cheaper initially, then add on what they see as "unforeseen extras".

So if you are looking for a new home Extension or Loft Conversion then get in touch today!

On Budget... On Time... Everytime .
