CLIENT TESTIMONIALS

“Iain is a wonderful person to work with; easy-going, attentive, creative and with a lovely sense of humour. We found his designs inspiring and his attention to detail is excellent and really appreciated by our builders too. If there is another opportunity I hope that we can work with him again and I could not recommend him enough.”

“Iain produced the technical drawing set for our whole house renovation and extension. This was a major project lasting almost a year, all parts of the building, grounds and outbuildings were stripped back, re-modelled and rebuilt. Iain was readily available for the duration, always responsive, both creative and pragmatic, helping us to achieve our dream home with a constrained budget, and at a very reasonable price for his services. Iain has a gentle and friendly manner, collaborating easily with main contractor and all trades on site, unphased and reassuring at points of pressure. With a keen eye for design, Iain was able to suggest minor design adjustments on site which have had a hugely positive impact on the overall space and how we live in it. I thoroughly recommend Iain for your architectural project - I wouldn't use anyone else now!”
