Driveways (Paved & Loose)- 6 Jul 2026
Jeromy and his team did a fantastic job on my new driveway. They arrived on time, worked efficiently, and kept everything tidy throughout. The finish is neat, durable, and exactly what we agreed. Great communication, fair pricing, and reliable service. I’d highly recommend Jeromy to anyone looking for a trustworthy builder.
TRIL DESIGN & DEVELOPMENTS
Rating: 5 out of 5
Extension Builder in Milton Keynes
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.

Tril Design provided exemplary service, throughout the entire project. Aiden is a pleasure to work with, along with all tradesmen he employed. Aiden was always on hand to assist and reassure whenever required and was willing to make alterations at very short notice when they were requested. I wouldn't hesitate in recommending Tril Design & Developments to friends and family.

Conversions - General- 8 Oct 2022
Valentin, Dan and Chris did a great job turning an old wooden shed into a beautiful teenage den / home office. They stripped the shed down to the original wooden frame, replaced the roof and cladding, subdivided the internal space into two rooms and a small shower room. The job was reasonably priced though there was a little scope creep much of it due to additions to the original specification that resulted in an increase in price. With hindsight we should have made sure we kept track of additional work. They were friendly, tidy and considerate in the work and the dog loved having them around. They were professional and hardworking and we were pleased with the final result which was excellent value for money. We would recommend Valentin and his team and will have them back to do more work for us.

Extensions- 16 Sep 2021
Very happy with the extension. Eddie and his team were best priced which was the reason we went with them, and he brought in a crack team of brickies, roofers and notable mention to the tilers.

Bricklaying- 19 Apr 2022
Could not be happier. Marshal is professional, kind and sensitive to individual building needs. Got the job done to an incredible standard for cheaper than any of the other quotes and in very good time. I had a section of garden wall that had been pushed over by tree roots and no access to the garden other than through the house. Marshal and his guys were kind, friendly, kept the house clean on their way through and did a fantastic job. Cody, one of marshals employees was particularly kind and even took time to answer my children's endless questions. I'll be using this company again for sure and would recommend to anyone who needs building work doing.
