"Sean was instrumental in helping us achieve our dream home. He helped us with the design, planning permission and many of the headaches through the construction stage.
From the other architects we spoke to Sean was able to provide us with great advice which made us confident he' was the right choice."
"Sean is simply awesome. Sean is a highly competent architect and the standard of his work and quality of presentations really is 5 stars. Before engaging Sean my partner and I undertook a review of all local architects and interviewed 3.
Sean was competitively priced and seemed very knowledgeable and his fee/work proposal was the best by far. Throughout all stages of the project Sean has been contactable for advice and I would have no problem recommending him. we would certainly use his services again."
"Sean and Maverick were fantastic from start to finish in helping us achieve our house extension and refurbishment project to our house.
Everything from the planning permission, building regulations and construction were streamlined and managed with ease, if you're looking for an architect I'd have to recommend them."
"Of all the bids Sean was the only one that understood exactly what I needed and offered a fixed fee. Working with him was a pleasure, took the time to explain things and the turnaround was very impressive. I am a very pleased client and would highly recommend."
