Extensions- 12 May 2026
Maninder recently built an outhouse for us and we were extremely impressed with both the quality of work and his honesty throughout the project. Everything was completed exactly as promised, with no hidden costs or unexpected extras. The workmanship was excellent, and even other tradespeople have commented on the high standard of the build. What also stood out was that Maninder always recommended the right approach, even when it meant extra work for his team. Highly recommended.

Conversions - General- 6 Jun 2017
Gina and her team have done a fantastic job in my home. They removed two chimney stacks, a load bearing wall, fitted new kitchen, laid flooring, and plastered two rooms. Gina had a detailed written quote within 24 hours of viewing the property. The quote very reasonable. The team couldn't do enough for me, very professional, friendly and efficient workers. So much so, I have already recommended the team to other people needing work. And will have them back soon when I have enough money together. Thank you Gina and the "boys" Louise

Tom from the start was very responsive and extremely professional. I needed some work being done in my flat included a bath being replaced, which managed everything including the sourcing of the new bath, which took a lot of pressure off me. Tom comes highly recommended and is now about to start some work round our house too.

Blueline completed the work to the exact high standard i was hoping for, while remaining on budget and estimated timescales - the three things that were most important to us! They were punctual, practical, knowledgeable and willing to give advice when either needed or when something could potentially be improved. They were always available to talk through what was happening at every stage of our job, with any complications arising, and importantly solutions to any problems. They knew their stuff and got the job done without any hassle either. They even came back after the job was finished to shift some pipework which i had an extra requirement for. The best feedback i could give is that we will go straight to them for any work we require in the future, and have already recommended them to friends.

Conversions - General- 29 May 2022
We took a longtime selecting our builder and so glad we chose Nero. Every builder must always think twice before working for architects on their own home! and Nero and his team worked diligently to meet our exacting standards with great communication throughout the whole process. We can't edit the original description of the works but we ended up completely refurbishing the whole of our ground floor, the rear elevation of the house, re-wiring, specialist lighting, re-plumbing, re-roofing, new front garden wall, victorian tiled garden path and external decking too. We also had a high quality parquet floor laid with new underfloor heating and each line of tiles was meticulously set out which looks fantastic!! Happy to recommend and give reference too.

We hired Brits Constructions for our full house internal renovation and we have a smile on our face when the project is completed. We are glad that we chose the right team for this. Syed Shahbaz Ali and his team accommodated for all our requirements from start to end of the project. As the project moved forward, they also suggested us improvements which proved to be right option for us. Both Ali and his team is very polite and listened to all our feedback, concerns and requirements with patience and addressed them accordingly. In term's of skills and expertise the team was quite good in executing the work and overall we are satisfied on their service.
