Kitchen Fitting- 1 May 2019
Graham and his team came dead on time, and refitted a new 3 mtr worktop, new sink with cupboards underneath and left the kitchen clean and tidy. I can't praise the guys enough for the finish of work and professionalism. Have already asked Graham to quote for another job I am that pleased, plus the price was fair to both sides. Thanks team.

TRIL DESIGN & DEVELOPMENTS
Rating: 5 out of 5
Extension Builder in Letchworth Garden City
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.

The Job was to extend the rear of the house on the ground floor, open up the kitchen and reception room into one open plan living area, to refresh the rest of the house which included new plaster skim, doors and frames and to fit new bathrooms and kitchen as well as an rewire on the whole house and the construction of a retaining wall in the garden to accommodate the extension. Florins team were excellent from start to finish, the whole project was completed in record time to a very high standard. The 10 weeks turnaround was incredible, we were very happy that Florin was always here at the property or on the end of the phone throughout the process, his professional advice and smart ideas made for a smooth transition from room to room. The team were very hard working, polite and knowledgeable, these guys worked very hard and very quickly which was amazing to see and I was very grateful we were able to move into the property earlier than planned which even saved us money on the temporary accommodation we had! Can’t thank you enough Florin, any small issues we had were dealt with quickly and smoothly, I love the house, the level of work and would 100% use Florin and his team on my next project!

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.
