Murat has continued to go out of his way to help me on my house building journey. From shaping the plans and helping us to figure out what made most sense in our property, to getting through a very tricky planning process! He has since been on hand when I’ve needed him for other stuff. Would strongly recommend his services

I had a really great experience with MM Architecture & Structure, and I’m very grateful to Mr Amiri and his team for all their hard work. From the very beginning, they took care of everything for me, which made the whole process much less stressful.
They visited my site, prepared all the drawings, and handled the full planning permission application on my behalf. I really appreciated how clearly everything was explained and how easy they were to communicate with throughout.
The Lambeth planning team reviewed the application within the 8 weeks stated on their website and gave a positive decision, which I was very happy about.
Overall, I felt I was in safe hands from start to finish. Mr Amiri and his team did an excellent job, and I wouldn’t hesitate to recommend them to anyone needing professional and reliable architectural services.
