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!
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.

Services
For over 35 years Cox Format Loft Conversion specialists in North London have been helping clients maximise the space potential in their existing property. Cox Format's dedicated, experienced and trusted team can expertly assist from planning to completion stages. With extensive knowledge and experience of loft conversions as well as working with North London planning we are the perfect choice!
It's human nature to want to find a bargain and get the best deal you can, and this is no different when choosing a builder to building an extension or a loft conversion. However where your home is concerned, cheapest is not always best. We've all seen those programmes about 'cowboy' builders and how they cut corners to do a job as cheaply as possible.
At Cox Format we guarantee our prices for extensions in North London and Herts and the quality of our workmanship on all of our jobs. We have been completing house extensions in the North London and Herts area for since the 1980's and have a loyal customer base to prove it. If you wish to see some examples of our single and multi-storey extensions that have completed in the local area then please take a look at our gallery pages.

Report
After several glowing recommendations from business acquaintances about work that Cox Format had undertaken for them, and finding I needed a new roof too, we booked a consultation with Peter Maton the CEO. Peter visited us with Mark Rossi who was to become our Project Manager. With both, their experience and professionalism was immediately evident and reassured us from the start. One of the things that really sets Cox Format apart is that they deal with the job from startto finish. They designed the loft along with all structural elements, and dealt with the council’s Planning and Building

We have now used Cox Format on 3 separate occasions over many years to carry out loft conversions and kitchen extension. They have consistently worked to a very high standard. In addition to great workmanship (with zero snagging / problems) they are timely, polite and courteous, and they respond to any queries / issues very promptly. Highly recommend.
