We had a fantastic experience with Happy Building. Geo who was brilliant. We'd been through a few architects before who either couldn't translate what we wanted into a good approach, or who were more fixated on delivering their own vision versus ours. Geo was brilliant - he spent a lot of time with us to understand the dream we had for our house, was brilliant and patient in helping us make decisions, and translated all of this into a wonderful and exciting architectural plan for our house, owning and delivering the whole planning. HB and Geo were fantastic - highly recommended.

Geo Wilkins was easy to work with and came up with some really good ideas! We were both very confident working with him, he was patient and kept us well informed, and we plan to work with his colleagues in Happy Building on to the next stage of our project. We will also be recommending Geo and Happy Building to friends, family and neighbours.

Building Plans for Ground Floor Rear Extension in Kingston - Tony, April 2023
We had a great experience with Happy Building. They arranged an initial face to face meeting in their office when most other architects were only happy to do phone consultations. The process was really smooth, reasonably priced and we found Chantelle to be super responsive. Would recommend - thank you!

The team at Happy Building are all very friendly and very helpful.

Architectural Design for Ground Floor Extension in Cheam - David, Nov 2022
I had an excellent experience with Happy Building Ltd. At the outset, Carlotta provided a detailed explanation of each stage of their process and I particularly liked that you received two design plans that included an estimate of costs. This helped ensure my plans were realistic and I wasn't expecting any extreme surprises. My designer, Geo was very creative and thoughtful towards my families particular needs. Everything was done efficiently and with an eye for detail. I was extremely grateful for the several redesigns and support through a stressful planning application.
Building Design for Two Storey Side Extension in Esher - Sallie, October 2022

Architectural Design for Loft Conversion in Streatham - Nida, April 2022
Very competent and professional engagement from the outset. The lead architect there, Anastasia Atanasova, was thorough and quick to tune into our wishes whilst bringing to life the 'art of the possible'. Superb collaboration throughout and I wouldn't hesitate to recommend Happy Building to friends and family, in fact I already have. If you are looking for a personalised experience, where you are put at the centre of the decision-making without having to be experienced yourself because everything is explained in ways that you can relate and contribute, then Happy Building is a great choice.
