Nico and the Greenbuild team are polite, professional, clean and tidy, hard and fast working and were a pleasure to work with. Having completed several renovation projects and new builds, I can safely say that this team was the best by a long shot. Highly recommended. I hope they are not to busy to start my next project!

Joinery & Cabinet Making- 23 Aug 2019
Can’t recommend Alex highly enough! He built wardrobes into our attic eaves, altered some stairs, and fitted our new wooden hallway flooring, all to an exceptional standard and at a very reasonable price. He was professional, tidy, efficient and consulted me every step of the way to ensure the finished design was exactly what I was after. I’ve already asked him about doing some future jobs I was that impressed.

KGH, led by Kev and his foreman David, did an absolutely amazing job. I cannot recommend them enough. This job was a complete rebuild. They gutted our two bedroom basement flat, reconfigured the layout according to our architects specifications, dug out the backyard (a 2 meter high retaining wall was pushed back a further 2 meters) and built an extension that is now our reception with a lovely skylight. The finish is high-end through out. The inevitable snags along the way that come with a job this large were dealt with immediately and always with a smile and positive attitude. All of this done on time and within budget. We were kept up to date throughout the process and were involved in all key decisions to ensure the end result matched our expectations. Great work guys!

Extensions- 16 Sep 2025
Steve and his crew did an amazing job turning my fag-packet designs and downloaded images into a proper, wonderful sound proof garden building, concrete external & rockwool cavity He’s a an old-school builder who does things the right way. His approach and mentality are always “how are we going to do this” rather than “I can’t do this,” I picked Steve on price and previous work. He came in middle price wise and was fair, it’s safe to say it was the right choice. He was left to his own devices, worked through all sorts of weather, and although the job took a little longer than expected because of that, he stuck firmly to his original quote. Although steve didn't know at the time, the garden room was my test for both quality, work ethic and trust, and Steve passed with flying colours. On the back of this, I’ve now commissioned him to build me a two-storey extension. I think I’ll buy him his own coffee machine for that project though! ;-) Thank you, Steve

Extensions- 29 Jun 2022
We hired Stefan & his team for a kitchen extension job. Stefan is professional & friendly and the team was very punctual, hardworking and always tidied up at the end of each day. Towards the middle/end of the job we did get a few unexpected bills which we hadn’t been discussed beforehand, and there were times when the team didn’t show up as planned, which was a bit stressful. Communication could have been better but overall it was a good experience and we ended up with a really nice kitchen extension.
