Graham Owner really knows his stuff. He listened to my ideas of what I wanted and added his own ideas and knowledge to make it better. He explained the quote and how additional work can be agreed. His guys arrived on-time and worked hard to make sure that they kept things tidy and as clean as possible given the nature of the work . Any issues they found were carefully explained and a way forward agreed with me before the work was done. The quality of the work was great and I got many of my neighbours and friends asking for Graham’s number so that they can call him. I would 100% recommend this company.

G&K are a fantastic firm that are professional and realible. Graham is very knowledgeable and very much in control of your project from start to finish. Nothing is too much trouble and he can sort anything! This is the third time we have used them for renovations and we wouldn’t use anyone else! Everything is explained to you and you are kept updated making the renovations a lot less stressful. Can’t thank you enough. We love our house now! Sarah and Steve.

Very happy with the work carried out by Graham and the team to re-build our extension. The builders arrived early each day to keep me updated with progress and to answer any questions I had. The site was kept tidy throughout the build, and all work was done to a high standard. Would definitely use G&K again!

“We contacted Graham and his team at the beginning of 2017 when we were looking to have a loft conversion and a single storey extension and I am so glad that we found him. We had spoken to virtually every builder in Chesterfield and were starting a feel a little disheartened with responses such as ‘the job was too big, it may take up to a year and I hope you’re moving out as it will be very invasive’.

Graham was like a breath of fresh air. He talked us through everything, gave us a reasonable price and quote us a 12 week turnaround time and never once did he imply that we wouldn’t be able to live there. When the job started the team were very friendly, polite and respectful of the fact that this was our home and not a building site and always made sure they cleaned up at the end of the day. They were always on site every morning no later than 8am, sometimes earlier and got stuck straight in every day. We also had Adam there every day which meant if we had any questions on how things were going he was up to date with everything. We had a few issues with our architect drawings, but again this did not seem to be an issue for Graham and his team, they never moaned, they just amended things as they needed to or asked us for our preferences on things if the plans didn’t seem to stack up.

Even though we had probably the wettest summer for a while, Graham still stuck to his timescale and had the job turned around in the 4 months he promised and to an excellent standard. I would recommend Graham 100% and will definitely use him again should we have any further work done. I would welcome anyone to come and look at his work on our property if you are looking for a builder and want to see the quality of his work first.”

We contacted Graham and his team to do a loft conversion along with a single storey rear extension. Their attention to detail has not gone unnoticed. All of the team were extremely polite and helpful and tidy. We were living in the property whilst this was going on and they have made what felt like a very daunting experience very enjoyable. We are extremely happy with their work and would not hesitate to recommend them.

They are very professional and employ skilled craftsmen who do an excellent job. This was a major undertaking and although there were a couple of ups and downs along the way, we would happily use them again and recommend them to anyone for similar jobs.

Work was carried out quickly and efficiently. The front of my house looks cared for once again. The men even hung my flower baskets for me.

G and K Developments were very professional and obviously take enormous pride in their work, no matter what the task. We had our conservatory and porch demolished, with the wall built up and prepped for a bi-fold door to be put in (which G and K did too). We also had all of the external brickwork repointed. Everything was done to an excellent standard – we couldn’t have been happier with the result and are now recommending them to everyone who asks for a good builder. A credit to the building trade!

Excellent service and professionalism from initial contact to completion. The team took real care to make the drive blend in with the existing portion. I was very impressed with the quality of the work from excavation to the final block being laid. Would highly recommend G & K.
