Our Reviews

What you can expect when working with our dedicated team.
We originally had another architect booked, who kept adding costs onto our project. We clearly specified we wanted all costs to be transparent from the beginning, which our first architects were NOT honest about.We decided to make the decision to find new architects, taking a huge risk, knowing we'd have to pay again for new CAD planning designs, which the first architects wouldn't give share with us.We chose Summit after a call with their BD, Mike. Our experience with Summit was seamless, comfortable and accommodating of our requests. Our main architect, Gus has been super responsive and a pleasure to work wit, as well as our Account Manager, Nicollete.One thing to mention, there were some additional costs at the end of our project, however Mike outlined these and we negotiated fairy as we had made some changes from the OG specification.We'd happily recommend Summit to our friends and family, and requests have already been coming in. 5 star service, thank you Summit team for all of your work!

We first met Oliver at another property, which we didn't purchase in the end but decided to go ahead with Summit Architecture because of how enthusiastic he was when we first met him. We didn't end up having Oliver design our build, as the area we moved to was no longer covered by him but have ended up with some plans we are very happy with. Summit have been great at updating our plans regularly, due to changes required by our builder and they have been to quick respond to these changes. We must also give huge praise to Nicolette, who has not only been great at keeping us updated throughout the process, regarding our plans but she was also a key part in helping overcome issues we had with our Party Wall surveyor. We had a number of communication issues with our Party Wall surveyor and she went above and beyond to ensure we received the report from him. Nicolette didn't need to do this for us but was very willing and happy to do so and for that we are very grateful. Thank you!

I have had an amazing experience with Summit Architecture. They have been attentive from beginning to end and I am so pleased with my new extension. Great team, I’d definitely use them again.

We recently employed Summit Architecture to aid in the design of our loft conversion in Kingston. We were very pleased with the service they provided and with the final design. We were assigned an architect, Carl, who was knowledgeable and easy to work with. Zoom calls and screen shares were set up as and when needed, which worked very well. Our requested revisions to the drawings were also carried out quickly. Summit used the software Revit to create our design in 3D, from which the 2D sections, elevations and plans were taken from. We thought this was a good approach and the final rendered images looked great. We will use Summit again in the future and would recommend them to others.

Summit have been a great help in our refurbishment and have helped and guided us through internal planning, structual calcs, planning and building regs. They even put us in touch with a number of quality contractors. Big thanks to Nicolette and the team for their continued willingness to help us out.
Great working with Eleni & the team. Really pleased with the drawing designs and the advice offered regarding the local authority planning permission. Looking forward to the rest of the process and hopefully starting the build soon!
