With a previous architect we had a disastrous start to our extension planning and our experience with Kingswood design could not have been more different. Kingswood Design 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 Kingswood Design to friends and neighbours.

Mrs. Brown, Oakwood Drive, St Albans

Right from the start they were responsive, delivered on time and managed the entire end to end process from design through to getting planning permission.  I would thoroughly recommend them.

Tim Brown

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.

Mr T Sahota, Prospect Lane, Harpenden

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.

Peter White, Managing Director, Graham & White Ltd

Kingswood 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.

Mr P Hughes, Mayfair Holdings

Another great design from KDR Architectural. A brilliant service with great attention to detail. Provided inspiring designs towards difficult planning issues.

Jason, Victoria Builders, Dunstable

This is the second time I have used KDR Architectural and the third time they have worked on our property – that in itself tells a story. I find their approach to projects, small or large, to be extremely professional with a good understanding and interpretation of client needs. Highly recommended.
