    We worked with Geo of Happy Building to get two designs and planning permission done for our side extension and garage extension and can not fault his process, he's been on point worked to our design spec and given us good advice on different options when we wanted to go over the top... Geo went through the Stage 1 process from Happy Building and we are looking to goingthrough Stage 2 with them

  • Designing a rear extension

    10Verified Review

    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. While we just had the first stage of designs and planning (only because we decided not to go ahead with the extension), we wouldn't hesitate to recommend them for this!

    10Verified Review

    We initially used Happy Building's Design and Planning Service, then selected them to build our project as we felt confident that they understood our vision and would deliver to a high specification. We were not disappointed. We found the whole team to be extremely helpful and supportive throughout the entire process. They delivered a build that was well beyond our expectations and we absolutely love our new home. Thank you so much to all the Happy Building team.

  • Side and loft extension

    2.75Verified Review

    We have a very poor experience with Happy building during our major buiding project. During the project we experienced numerous issues including poor project management, delays, incorrect products being ordered and delivered. They did not ensure building control signed off the various stages of the project which resulted in several post sign off vists to corretc errors. The standard they left the work was considerably below what we would have expected with scratchs on windows, marks on carpets, stains on newly laid tiles in bathroom as a few example. Do not this company.
