Bricklaying- 16 Oct 2022
First class job by Kieren and the guys. They did 2 garden walls, 2 planters and a bbq and sink area for us, which included some not so standard details. They seemed as excited by the job as we were and its always great to have someone feel passion and pride in what they do. Reliable and nice guys too. We're so pleased with what they've done and would 100% recommend.

Conversions - General- 4 Jan 2026
Pat was a pleasure to deal with from beginning to end he had everything covered and made the whole project a seamless experience. He provided me with a professional quote and had the patience to deal with my questions. He started the project on time svd no thing was too much trouble, when I needed a roofer to fix some issues with a leak he had someone on the job within a day. He handled every aspect of my garage conversion effortlessly and had the job finished on time right before Xmas. Would 100% use Pat again. Great guy who also knows good trades people. Thanks Pat.
TRIL DESIGN & DEVELOPMENTS
Rating: 5 out of 5
Extension Builder in Hemel Hempstead
Hi, we are TRIL DESIGN & DEVELOPMENTS and specialise in Extensions, Loft Conversions, Refurbishments, New Builds and smaller projects such as knock throughs, kitchen installs & bathroom refurbs. We are a family run business with our vetted/qualified trades-team, that we have been working alongside for many years and many projects. We find this to be particularly important part of our company structure, giving you and us peace of mind and a strong sense of trust throughout the project. We do not sub-contract our work out, giving us the the control to carry out the works from start to finish with a personal service. We have over 14 years experience in general building and project management. One of our fundamental values is communication between builder and client, which we believe is key to finding solutions, not problems. Unfortunately, our industry is plagued with opportunists and low budget builders, providing cheaper services at the cost of poor quality and budget control, which will inevitably cause issues throughout and after the project. We take pride in our realistic pricing, high quality of work, reputation, and service throughout. We have so many happy previous clients you can visit, talk with and view our work.

Extensions- 7 Mar 2023
My husband and I just bought a house and we were having a real hard time finding a good builder. We registered on MyBuilder and shortlisted a few tradesperson, we then came across this amazing team from XK contractors. They have literally and figuratively been a real blessing. 10 days and they changed the look of our house to our preference. I'm not just writing this review for the sake of it, but they're honestly real hardworking people. The main man- Xhezavir leads the team like a dream and they all know exactly what they're doing. Highly recommended, decent pricing, great work team, keep up the good work!! 👍
