“.... The Phoenix Garden charity appointed Gurmeet to design a purpose-built community building. Working with an architect who, from the outset, took the time to understand our requirements and how challenging constructing a new building is for a voluntary organisation was invaluable. Throughout the process, from the design stage to construction, Gurmeet was on-hand and willing to advise and guide us, negotiating clearly with good humour, all the while maintaining the vision of what our new building could be. As a result, we now have a beautiful award-winning building which fulfills our requirements.

We would have no hesitation in recommending Gurmeet as an architect: he really is very good.”
Phoenix Garden Trust, London

“Calm, thoughtful and second to none on spacial planning and layout, Gurmeet is a talented architect and a pleasure to work with”.
Katharine Redshaw, Lateral Property Developments Ltd.

“We feel very lucky to have had Gurmeet as our architect. The spaces he designed for us are beautiful. Our loft is stunning, and our kitchen has been transformed into a completely different place, warm, light and peaceful. We had prevaricated for years about how to improve the kitchen without extending it, and after two visits Gurmeet came up with an idea we had never thought of which has worked brilliantly. All our new rooms are full of simple but clever touches which we appreciate every day.

Gurmeet was also a pleasure to work with from start to finish. He listened to and worked with our ideas and kept the project moving forward. His involvement through the building process made construction much less stressful than it might have been and was invaluable to us as building novices.”
Kitty Stewart + Pedro Fernandes, Groombridge Road

“Huge thanks for all your help over the years - everything looks really amazing! ....You are a genius!”
