Whether the home improvement you have in mind is big or small, we understand that it’s a big decision, and you want to get it right. At KDR, we are architectural designers, not salespeople, so our main aim is to improve the practical and aesthetic use of space, leading to a much happier home and family. As a homeowner, if your house is not working for you, you always have the option to extend. Often an extension is a cost-effective investment – it can be more affordable than moving to a new house and increase the value of your property considerably.

Our reviews

With a previous architect we had a disastrous start to our extension planning and our experience with KDR could not have been more different. KDR were completely on-the-ball regarding the design requirements and the planning application process. Design changes requested by the council during the planning process were speedily resolved and we are very happy with the final design and build of our extension. In particular John recommended an extra small window in our main bedroom which has provided extra light (and many friends have commented that it was a good idea). We have already recommended KDR Architectural to friends and neighbours.

I have known Kevin Todd for about 25 years and during this time I have used his services many times and referred him to a number of friends and family. I have always found Kevin to be a highly knowledgeable in all relevant matters relating to Building Control, Planning Permission etc. He offers a friendly and personal service to ensure the client is happy. I would have no hesitation in recommending Kevin Todd and KDR Architectural.

We were very pleased with the speed and quality of response. John listens well to our ideas but also asks interesting questions and will offer up other ideas although he is happy to let us decide. You provided accurate, competitive quotes and delivered against them.

Mr & Mrs Newbert, Beacon View, Northall

From the outset Kevin Todd gave us excellent service, commencing with fast full plans design and specification being provided, thus helping to pull the project back onto schedule. He handled all planning paperwork, seeing it through to condition satisfaction and full plans building regulation approval. This work was technically challenging due to the building age, the current building regulations, and mixed building use. Completion of the work, and seeing the design morph into reality, has left us delighted with the very high design standard and competence demonstrated. We have no hesitation in recommending the KDR Architectural service.

KDR Architectural continually come up with inventive solutions to get more out of our sites, and they always put in the extra effort to ensure that things go smoothly. I couldn’t recommend them highly enough.
