Landscaping- 18 May 2021
Joe was professional and responsive for my posted job to do fencing and wood trim repairs. He was able to provide a quote quickly and did the work in quick fashion. I wasn't quite sure what was feasible, but Joe was able to provide good guidance on what could be done for the repairs. The quality of the workmanship seems to be high, and I am pleased with the result. I would definitely recommend Joe for this type of work.

Extensions- 10 Nov 2020
An outstanding team who clearly take pride in their work, it is the little things they think of that make a massive difference. We kept progress notes and any issue discussed and resolved proactively. Carried out some additional work that wasn’t initially quoted and did not charge extra. Shane himself has a fantastic desire to work and deliver. Even through the Covid, with most shops closed, Shane delivered. Would not hesitate to recommend.

TA Bhatti constructions did an excellent job in renovating my house, it was a 6 months long job where they pulled apart all the internal parts of the house and rebuilt it all. They did an excellent job in putting a new Kitchen, 2 bathrooms, new wiring, new plumbing and everything else. The thing I liked most was their finishing which was next to none. I will happily recommend TA Bhatti constructions to anyone looking to renovate their house or looking to do extensions or Loft conversion.

Restoration & Refurbishment- 14 Oct 2025
Peter and team did a brilliant job refurbishing our kitchen. He organised building control sign off for knocking down an internal wall. He sourced new glazing for us and designed and built a custom bench seat. He assisted us with ordering the right units for our kitchen. He was great at problem solving along the way e.g. cutting cornice to fit tricky corners. The team were courteous and left our house tidy at the end of each day.

Extensions- 9 Oct 2022
We engaged NB Building Services to build an extension (new garage and room at the rear) and extensively refurbish/remodel a bungalow. I met a number of builders/building contractors but I felt immediately comfortable with Nick right from the start. It was the first time we were ever starting such a project and we wanted to follow our instinct and go with someone we could be comfortable with over the duration of the project. Right from the start Nick came across as someone who is genuine and who looks to understand your requirements. Also, as my project had a few uncertainties that could affect the scope of the project I was looking for some flexibility and I felt that Nick and his team could provide that. Nick and his team (Stefan, Boris and Ilco) work very well together as a cohesive team. Nick provided a day-to-day customer contact while scheduling tasks on the building site and coordinating material deliveries. Every member of the team worked a full day and on occasions where it was important to finish something on the day, they would stay late to finish the job. What impressed me most when the work started is that the entire team is multiskilled – they do everything from bricklaying, timberwork, roofing, plaster/skimming etc. This helped me immensely when there were minor changes or modifications. That meant we didn’t have to wait for the bricklayer or plasterer to return to the site again. Nick also operated the heavy machinery like digger/breaker etc. Once the initial structure was complete the team again impressed me with their attention to detail when they moved inside to lay down plumbing, electrical wires, gas pipes etc. Nick and Stefan took the lead on the fine finishing tasks inside while Boris and Ilco provided important support and completed a lot of other tasks inside and out. It was during this critical phase when communication is most important that I appreciated Nick’s effort to keep us informed. As far as quality of work is concerned while we were happy with everything, I think the tiling work of both Nick and Stefan is outstanding. Our project lasted for about 8 months and while there were lots of discussions on areas of the project that I did not understand and I asked a lot of questions and also changed my mind on some things I don’t remember I we ever even had a minor argument. This I felt was an important win. Nick was also generous with his time and provided help to other trades who came on site e.g. window fitters, garage door installers; boiler installers; electricians etc. Nick and his team returned a few months later to lay down a patio with porcelain tiles for us and also a driveway with block paving. Once again Nick and his team discussed with us in detail what we wanted and provided suggestions based on their experience.

Extensions- 18 Oct 2017
I asked Prohaus to undertake a ground floor side return and rear extension as part of the refurbishment of my flat in Putney. I have used many builders before on development projects but was especially impressed with Naz and his team on this build. It was the first time I used them and won’t be the last. Naz was great to work with, the whole build went smoothly and he always had a positive attitude and solution to any unexpected issue. The build came in on time and budget which was very impressive in itself. All in all I would highly recommend him.

Bill and his team were excellent, we had the quote within a few days of visiting and he was able to start work the very next week. Everything was kept tidy at the end of each day, his team were quick and efficient and everything is to a top standard. Bill’s communication was also excellent!
