Architecture- 5 May 2018
Contracted to provide options for a new garage office and storage solution. They turned up promptly and were very polite and professional. Through many discussions they ultimately offered up a very good bespoke solution for our situation and once planning is approved we will have no issue with looking to them to complete the actual build. We have had a lot of issues in the past finding reliable trades but with ArhiTERRA design and build we felt confident in their ability to both visualise and implement the build as well as follow through on their promises. I would say that for anyone considering discussing a project with them that it is worth your time to at least have a meeting with them and judge for yourself.

Extensions- 29 Aug 2021
Communicated well at the start with reasonable cost. work was done well but the finishing was not so great as expected. The end cost was very expensive. Charged by the hour, the team were very slow which was upsetting to see me pay for time where they sat around not doing much. Ensure to agree fixed price. Communication after job is poor, double glazing has warranty which now not being able to communicate with kostas having to pay to get things done that should be covered in warranty. Central heating give huge problems. Do not use for big jobs

Paul did an amazing job at my 3 bed, he built a shower room and toilet area downstairs from scratch and plastered and repainted the whole house with his specialist team within 2 weeks. This has been amazing as other contractors quoted between 6 weeks. I will definitely be using Paul's services in future as he sticks to the price quoted and is trustworthy

Satnam and his team arrived promptly on time as agreed, i was highly impressed with the perfection they did the job. The room was total mess and they converted that room into a beautiful yoga studio. They worked fast and to perfection. The price was good. They did not ask money in advance which was good as i paid them after the job was done to my satisfaction. Now i have also asked them to do more work in my house. Thank you Satnam and the team.

Hard Flooring- 2 Apr 2019
We are thrilled with our new floor! I’m so pleased we went with Treewood to lay parquet flooring in our downstairs lounge. Andrew has done the most amazing work and his attention to detail is fantastic. We moved out of the house while the work was going on as we have a baby, and Andrew kept us to up date each day with his progress and he even sent pictures. I would highly recommend Treewood to anyone needing new flooring at exceptional quality! Carly

Quality Builders completed a remarkable domer and loft conversion for us on 2/10/2023, and we couldn't be more pleased with the results. From the outset, their professionalism and attention to detail were evident. The initial consultation was thorough, and they took the time to understand our vision for the space. Throughout the project, communication was excellent, with regular updates on progress and any necessary adjustments. The craftsmanship displayed by Quality Builders was exceptional. Every aspect of the conversion, from structural work to finishing touches, was executed with precision and care. Their team of builders and contractors demonstrated expertise and skill, resulting in a finished product that exceeded our expectations. Not only did Quality Builders deliver on time, but they also adhered to budgetary constraints without compromising quality. Their transparency and honesty throughout the process gave us peace of mind and confidence in their abilities. The transformation of our space is truly remarkable. The addition of the domer and loft has added both aesthetic appeal and practical functionality to our home. The new space is light-filled, spacious, and seamlessly integrated with the existing structure. Overall, we cannot recommend Quality Builders highly enough. Their commitment to excellence, attention to detail, and professionalism set them apart in the industry. If you're considering a home renovation project, look no further than Quality Builders for exceptional results.
