Our Reviews

What you can expect when working with our dedicated team.
We can't thank Oliver enough for making the whole process seem simple to us. From our initial meeting to the plans passing through the local authority he kept us informed all the way. Our circumstances were probably a little different to other peoples as we needed drawings and planning passed asap, Toms experience certainly didnt disappoint .We wouldn't hesitate to recommend Summit architecture and we would definitely use them again if we did any future projects.

We received a planning refusal using a different firm so were feeling quite dejected. Fortunately, we found Summit who created a great design and gave us some invaluable advice which would save us a lot of hassle later. Full planning was granted without any real issues. Really happy with the outcome and would recommend them. I thought Nicholette was especially great at her job.
An excellent experience. I was buying a house and needed to make sure that some structural work had been done to a high standard. It was a complex task, and the people selling the house were a bit difficult. But the Summit team stuck with it, and were professional, polite and creative. I received the structural report in good time. They were responsive and also their quote was the best value. I would recommend them without hesitation.

A Fantastic and commitment team - who make things happen. I am in the middle of the 2-stoery side extension with Summit Architecture team, and so far I have found a lot of professionalism, flexibility and the right customer winning attitude in all the team members.

We engaged the services of Oliver Newell at Base Architecture Ltd last year (2018) and found him to be professional, dedicated and supportive of our proposal from start to finish.He kept us informed throughout the process giving clear explanations and never once did we feel unsure of him. We would highly recommend him to others and are thoroughly happy with the excellent service we received.

I required structural surveys for a basement renovation. Summit were very helpful in organising someone to come over at short notice and at a very reasonable price. Quality of work was A grade and delivered ahead of time, all correspondence was swift and polite. Exactly what I needed and would have absolutely no issue using again
