Local testimonials and reviews:

“We engaged Square One to remodel an existing 1st floor extension. Square One produced an attractive solution that blends the older part of the house with the new. The quality of the drawings and attention to detail were excellent, and the client relationship very well managed. Now constructed, we are very happy with the result..” Client in South West London

1. costs were clearly laid out from the start and were kept within the budget.
2. Iacopo helped us throughout the process, being available at key stages of the project.
3. They helped us with recommendations for builders, surveyors etc which cut time and costs.
4. The drawings provided were very clear and detailed.
5. Plans included things like lighting layout which helped when it came to build.” Client in South West London

“We had a wonderful experience with Iacopo as we looked to extend into our loft. He was responsive and solved problems in a thoughtful way. His designs have produced a brilliant outcome for us that has most effectively used the space available. Building Control passed with no issues, in large part to Iacopo’s excellent and detailed designs.” Client in South West London
