"Nothing but positive words to say about our experience with Happy Building so far. Geo took our brief and nailed it more or less straight away and we've been impressed with the service to date. Working with Geo on our project has made life a whole lot easier & something that initially seemed so daunting/stressful has so far been a delightfully calm experience. Can't wait to see what comes next."

“We chose Happy Building because they provide both the design and build process, and we had seen their local projects and were impressed. Happy Building has a straightforward process — we knew exactly what was happening and when. We knew what the cost would be and there were no surprises. They were proactive in their approach to any challenges that came up — they always came with a solution. Their team were accessible, engaged, and helpful at all stages. The build has transformed our house and changed the way we live in it — it’s better than we thought it would be!”
“We were very pleased with our experience working with Happy Building, especially Geo. He designed us a range of fantastic designs, including costing them up transparently and fairly. He was patient with our differing decisions, gave really sound advice, and communicated with us promptly and clearly. We wouldn't hesitate to recommend them!”
