a family run business


Urban Design Build was founded by brothers Ed and James Windsor over 20 years ago to specialise in residential property. Back then, we were a small family business, dedicated to providing superior construction and renovation services to our community. Today, not much has changed, other than our customer base has grown larger and broadened, taking us further afield.

Professional Team



    Ed & the whole team at Urban Design Build were absolutely fantastic at every stage of our full-flat renovation. They were great with our listed building consent application (and appeal!) and in finding the perfect specialists for things like cabinets and a glass wall between the entryway and the lounge. When things went wrong (we found asbestos, for example) they solved everything quickly and without fuss, and didn’t let it delay the project too much. They’ve also been fantastic at fixing the snags since the project finished. I couldn’t be happier with their work or their level of service, and I’d highly recommend them.

    Energy Efficient House – Muswell Hill
      Energy Efficient House – Muswell Hill

      Paul Bragman

      We chose Urban Design because they had the knowledge and the skills set to help create a more energy efficient house. We had recently bought a large four bedroom house that was in poor repair and we needed to do the work to it before we moved in. Ed and his team went through with us the types of green technologies we could use and their potential cost savings. He then provided a clear and understandable quote with a timetable for getting the work done. We are now in a warm and well designed house.

        I have been in my new studio now for three months and am really enjoying it! James and Ed dealt with all the planning and design and I was able to stay in the house and work while the project was ongoing. All the guys were polite and dealt with any request in a professional manner. I would not hesitate to recommend them.

          Everyone who comes to our new home in Kentish Town admires the tasteful work carried out by Edward Windsor and his team. What was particularly impressive was the versatility and flexibility of the work involving building, decorating, carpentry, plumbing, and electricity. All done to a very high standard, on time and with great courtesy and good humour shown through out. Would highly recommend them.
