Irvine Jones Design provided an exceptional service with great vision. They took on board all of our needs and requests and produced quality plans and drawings that have enabled us to construct a beautiful home. They also handled all of the planning submissions and communications taking the pain out of that process, while also being available for any questions or issues during the build, and we had a lot. They were a pleasure to work with and I can highly recommend them for your planning and architectural needs.


Irvine Jones Design were originally brought in to get me from a blank canvas stage, design and through planning up to the first day of build for my loft conversion of my Victorian house in London which was all a success. I opted to source the building company and project manage myself and as it happened I didn't make the best choice and many issues ensued turning it into a difficult job, but thankfully I was back on to Daniel quite a bit over the following months and he made the whole ordeal much better. With hindsight I would've gone all in with IJD from start to finish, but you live and learn.
