Benjamin and his team did a fantastic job on my property building a 6m by 6m Extension walls in only 2 days, it was done ahead of time and on budget. He was very conscientious and nothing was to much trouble. Done all the pictures of each step along the way needed for Building Control Guy. The quality and workmanship was first class and I would definitely recommend him for all types of building/refurbishment work.”

Nanad and his team have been wonderful from day one. We have had them with us a number of weeks doing all the jobs they quoted for and more, they are fast efficient and courteous of the fact we lived in for a lot of the work.

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.

Bathroom Fitting- 29 Apr 2023
Many thanks to Kris abd Kane on a job well done. Despite the very tight schedule, they completely refurbished our bathroom transforming it to a high-end (hotel standard) wet room. Kris's original quote was very competitive. There were extras, but these were very reasonable. Once the job was completed Kris actually came back to install 4 or 5 grab bars without additional cost. Kris, and Kane are both very easy to get on with; thoughtful and calm characters. I travelled abroad during the job; Kris contacted me regularly and responded promptly when I reached out to him. As with any job' there were glitches but Kris's solution focus approach ensured a good outcome. Hope to work with this company again.

Fencing- 13 Mar 2026
We hired Bawa to install new fencing, and he did a fantastic job from start to finish. You can immediately tell he’s an all-rounder who understands construction very well. The work was carried out efficiently and to a high standard. Bawa has a great attitude, is very hard-working, and clearly takes pride in what he does. Communication was easy throughout, and the whole process felt smooth and professional. It was a real pleasure having Bawa work for us, and I wouldn’t hesitate to recommend him.

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

Very professional and organised. My rear extension renovation was impeccable, thorough knowledge of building regulations with a variety of services to choose from really put me at ease. The venetian plaster feature wall has become the centrepiece of our home.

Extensions- 26 May 2021
Ali Revani at Halibuild provided us with a quote which we accepted. 3 days before the job start date Ali Rezvani called and explained that they had under priced and they would want another £3000 to start the contract. Ali Rezvani then started the job but again admitted that they under priced the job and walked off the site several months into the project after the following major quality issues which needed to be addressed: Pouring the foundations in the wrong place, building the extension in the wrong place, building the roof incorrectly, installed roof steels in the incorrect position, built the extension rear wall too high, the plumbing to the boiler needed to be redone, all the plastering has had to be redone, skirtings needed to be redone, staircase had to be rebuilt. The list goes on and is 40+ points long. This has been a terrible experience and we face serious losses and a stressful dispute."
