Expertly built. Trusted with over 35 years of experience.

CFD: Award winning, Which? trusted building company

 

Cox Format Developments Limited is an award winning, professional building company specialising in the development of extensions and loft conversions in and around North London, including Barnet, Enfield and Hertfordshire. We have maintained our Which? Trusted Trader status for a number of years. We are extremely proud of the reputation we have built up and we are happy to say that 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 realistic price for a fixed scope of work and sticking to it. Unless you instruct us to, we never add on "extras" as some less reputable builders do as their standard practice. The price we quote is the price you pay!

 
 
 

We can provide a full range of loft conversions for a wide variety of properties

 

We guarantee our prices and the quality of our workmanship on all of our jobs

 

Unsure what you need? That’s OK, our experienced team will travel throughout the North London area to visit you at your property, they will talk you through the different options available to you and discuss whether a loft conversion, extension or a combination of the two is the best option. We always match your requirements in terms of design and budget, listening to your views and ideas and advising on the best way to realise them.

Because we are professionals and have been operating in Barnet, Enfield, Hertfordshire and North London for 35 years, we have a lot of knowledge surrounding local planning as well as being able to 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 loft conversion or an extension to your home then get in touch today! 

What our clients say
about CFD!

 
 
 
 

“After meeting Peter and Mark I was convinced that they were highly motivated to get the whole job complete in around 12 weeks which was important to us as we would be living in the property. I was extremely happy with the whole process and the end result. The CFD team expertly lead by James were all a pleasure to have in the house and made the whole job as stress free as possible. I wouldn't hesitate to work with them again in the future.”

— Jon in Greater London | March 2024
