Side Extension / Annex

Verified Review

We had a large extension built on the side of our house an annex with it's own boiler, bathroom, kitchen and bedroom, around 65m2 in total. Kris and his team were great throughout the whole process, and particularly with the care put in to making sure the bricks and even the mortar matched as close as possible to the original 140 year old property. The finish quality inside has been great, and the whole project, which was huge, was finished on time as required.

Brickwork to rear renovation

Verified Review

Kris and his lovely team have done a fantastic job with the brickwork to our large rear renovation. They are hardworking, honest and reliable. They take genuine pride in their work and really care about completing it to the highest standard. I couldn’t be happier with the workmanship and wouldn’t hesitate to use them again or recommend them. They were an absolute pleasure to have worked with.

Kitchen / dining room renovation

Verified Review

Kris and his team carried out some major remodeling of our kitchen and back room to create a large open kitchen / dining room space. Kris does a fantastic job of managing everyone and really takes as much stress as possible out of such a disruptive project. He's also really considerate and conscious of the impact this type of work has on our family, especially during school holidays. We had people constantly in and out of the house for a couple of months with this project, and pretty much everyone was fantastic and really friendly.

Large double loft conversion

Verified Review

We have been working with Kris and his team for about 9 months on four major projects across our house. This part of the project involved converting our loft to two large bedrooms with some huge structural steels, creating a shower room, and building a new staircase. We have 8 velux windows (four of them are the extra large PK10 windows), which are fantastic and give so much light and fantastic views. Kris and team did a great job with all the work, including the bespoke cupboards.

Large rear extension and side utility extension

Verified Review

Kris and his team of experienced tradesmen did a fantastic job on our two extensions. We had a large living room and side utility built, both with beautiful pitched roofs. All of the guys working on the project were polite, courteous and great with our two young children keeping the disruption to a minimum. The work was carried out to an exceptionally high standard and we are delighted with our new home. Would highly recommend KJ’s building contractors Ltd.

A small side and rear extension and internal reconfiguration.

Verified Review

Kris and his team did an absolutely excellent job on our house. The job had quite a few complications along the way and Kris went above and beyond to find high quality, cost effective solutions. He always took time to explain all stages of the build, the team arrived on time day after day and worked incredibly hard and at the end of the day everything was left tidy. I would highly recommend this company as their experience and commitment to high quality work made all the difference.
