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

Bathroom Fitting- 9 Jan 2015
Aggi and Pedro were excellent. They helped me to decide what fixtures and fittings I needed (including also doing some research themselves) and when it came to fitting the new bathroom they did it to a high standard and were tidy/cleaned up after themselves. I would recommend them.

Tiling- 11 Jun 2025
I hired for just for bathroom and toilet tiling, However due to the diligence, attention to detail, honesty and work ethics of Muro construct, I hired him to decorate my entire house, this includes everything form stripping wallpaper and painting, floorings, tiling, fixing doors, putting up all my new furniture including a very compl bunk bed for my children room. This builder works really hard and time efficient. He has helped transform my house into a luxurious living space and I am not exaggerating when I say that the price is very fair, I have had three times the quotes for less the quality. I will be using the builder for future jobs.

Extensions- 4 Aug 2020
On a cold November evening, Tony and his team turned up to provide a quote and within a week this was received. The quoted price came in the middle of the pile, which was a good start and aligned closely to the ballpark figure I'd received from a friend who was also in the trade. We then visited a site they were finishing off, and Tony had the confidence to ask us to speak to the client without him there and they gave us the confidence to proceed. They started in January 2020 and rapidly moved through the works and engaged closely with my architect, Structural engineer and building control and proceeded based on their recommendations strictly. We lived in the property as build progressed and the team ensured that the site was secure every evening and we were safe. As COVID-19 hit and we went into Lockdown, the team continued to come and work (we were separated from them as the house was boarded up) and the only challenge was getting supplies. Tony scoured all over London, picking up items as best as he could and work continued. Once they'd broken through into the old part of the house they continued to progress rapidly and showed utter professionalism. The team lead's attention to detail is impressive, and he gave great recommendations on what would be the right approach when we were laying out features such as window sizing and lighting. The standard of work is excellent and I would highly recommend them.

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.

Tudor did a great job on our kitchen. He kept us informed on progress all the way through the job allowing time in the morning for questions and then getting on with the work during the day. At the end of each day he showed us and spoke with us about the excellent progress he had made. Very pleased with our lovely new kitchen which is clean, bright and spacious.

Jack built a brick buttress to structurally support my garden wall. Originally I was going to rebuild the entire wall, but Jack’s advice to build a buttress saved me a lot of money! The job was done quickly, affordably and to a high standard. Would highly recommend.
