Extensions- 22 May 2019
Jacob was very accommodating and flexible. His team were great and he completed the work nicely. There was some splatter from the cementing on to my neighbour's wall. He tried to clean it off but it wouldn't all come off. Therefore, he went out and bought some paint and repainted their wall. I would get him back for more work without hesitation. When looking for a builder - they have to be honest, work hard and to an excellent quality without cutting corners. They should be responsible to ensure neighbours property isn't damaged and provide consultancy as what we want and want is realistic can differ significantly! - and if any issues rectify them once the job is complete and of course provide good after sales. I have used several builders over the years - very few tick all of the above boxes. Jacob certainly does.

Electrical- 26 Jul 2026
Genuinely one of the worst builders we have come across. David rewired the flat and Stefan plastered the hallway. David is NOT qualified as an electrician and cut corners wherever he could. David leveraged us for money mid job and in the end left the job without finishing and without providing a certificate. David ran cables behind door frames (awful idea), got the cheapest material, forgot where holes were for spotlights and switches among many issues which meant we had to constantly ask our builders to fill the holes and make good. Stefan did the hallway plastering without putting on mesh. The plaster cracked within 2 weeks and the paint keeps cracking and will be a constant problem. When asked to come back and fix the issue - he point blank refused. They were the cheapest quote but we really hope we had gone to someone else

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.

Damp Proofing- 11 May 2026
My experience with Samuel was excellent. He provided a professional, comprehensive, and high-value damp survey for my basement. The final report was very thorough, including a detailed technical assessment and numerous photographs that clearly explained the situation. What really stood out was his willingness to answer several follow-up questions regarding the specific remedial work he suggested. His expertise helped clarify that the issues were environmental rather than structural, which provided great peace of mind. Highly recommended for anyone needing a clear, honest, and professional assessment.

Conversions - General- 6 Apr 2010
After being let down by our previous builder, shortly before work was due to start, we were informed about this website, and somewhat hesitantly posted our garage conversion and kitchen renovation onto the site. After obtaining quotes from 3 builders, we decided to hire Nick cos of his straightforward and honest attitude to the job. We spoke with a couple of people that Nick had previously done work for, and they were very complimentary, so this just confirmed our decision to hire Nick. We have never undertaken any extensive building work before and were therefore nervous about the work starting, however I can honestly say that Nick was absolutely fantastic from start to finish of the project. Nick and his team were extremely hard working (finished much sooner than we expected), they kept the house as clean as possible when completing such works, and were generally an absolute pleasure to have around the house. Nick's craftmanship is exemplary and was always there to discuss any changes, extras or cut backs when not required. I would not hesitate in recommending Nick to anyone, safe in the knowledge that I know he would do an exceptional job, in fact more than three people have already asked for his details upon seeing the great job that he has completed here!! Thanks Nick for everything!!
