Cox Format Developments

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!

Once you have had a loft conversion or home extension added to your home you will doubtless think about decorating. Our team includes experienced decorators who will be pleased to advise on options. Our decorators are generally very busy so please do ask us to arrange an appointment for you.

As the examples below depict, dormers are constructed by adding a vertical extension to the existing sloping roof of the house. This means that the walls in a dormer loft conversion are vertical and the ceiling is horizontal, resulting in a real feeling of space. It is not surprising then that the dormer loft conversion remains a very popular choice for our customers. Maximum space is added to your home internally and, as these images show, externally our expert team of tradesmen will seamlessly blend the dormer loft conversion with the exiting exterior of you home.
