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.

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.

Highly recommend!

Unlock your vision with our expert architectural design services tailored to your needs

We have a team of in-house RIBA accredited architects and architectural designers. If you're unsure where to start, we recommend arranging a meeting with one of our qualified designers to discuss your ideas and give you advice on if your project will require planning permission.
To kick-start the creative process, we'll conduct a detailed survey to gather essential information. Within three weeks, we'll present you with two design concepts that showcase the full potential of your project. Why two options? Creative variation often adds value while reducing construction costs. To assist you in decision-making, we also conduct a feasibility study to provide an estimate of the build cost for both designs. This way, you have the freedom to choose the option that best balances excitement, practicality, and cost-effectiveness.
