Plastering- 25 Feb 2020
Rob provided a very reasonable quote and started work on time as agreed. He scraped the artex, boarded sections, prepped and plastered both ceilings over two evenings to a very high standard. Both ceilings were ready to paint after a few days drying and were smooth with no trowel marks or hairline cracks at all. Rob also assisted with measuring up my kitchen for a new kitchen to be installed, he provided a better quote than Wren to fit the new kitchen, I will be proceeding with Rob to fit my new kitchen units based on the advice he has given me and the high standard of work he has carried out for me over the past couple of weeks. I would highly recommend Rob to anybody and I will be contacting him again for any future work I need assistance with whilst refurbishing my new property.

Extensions- 24 Apr 2019
Darren was on site every day without fail. His work was 1st class. He knows his job and is very experienced. He was able to give us a start and finish date and he kept to those dates. He cleared and cleaned the site every day. He was an absolute joy to be around and went the extra mile to ensure we were pleased with his work. I would not hesitate to recommend him. His brickwork is a pleasure to look at and both the extensions he built - a rear extension with bi-fold doors, and a side extension (the garage) both look as if they've always been there. Craftsmanship at its best. He knows the building regs required, his standards are 100% good. Darren's prices are extremely competitive, he's no rip-off merchant.

TRIL DESIGN & DEVELOPMENTS
Rating: 5 out of 5
Extension Builder in Biggleswade
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.
