Conversions - General- 23 Jul 2025
I recently had the pleasure of working with Teimo and his team on a full renovation of a probate house, and I couldn't be happier with the results. The entire house needed a complete overhaul, including two new bathrooms, a kitchen extension, new doors, skirting, walls, plumbing, electrics, as well as front garden paving, a brick wall, and back garden fencing. The quality of the work is outstanding. Teimo and his team take immense pride in everything they do, and it really shows in the final product. They are not only highly skilled but also incredibly polite and tidy, ensuring the worksite remained clean throughout. They worked hard, from 8:30 AM to 5:30 PM every day, and completed the project on time without any issues. What truly stands out about Teimo is his honesty and clear communication. He’s upfront about everything, and you can trust that the price you’re quoted is the price you’ll pay—there are no surprise cost increases along the way I highly recommend Teimo and his team

Extensions- 8 Oct 2018
Alban completed a lateral kitchen extension for me in west London. Very happy with the results and to add my name to others that have given 100% positive feedback. What I particularly liked - (1) Alban took great care to protect the rest of my house while working (protection, covers etc), (2) his team were friendly and polite to neighbours. Building works are always noisy and disruptive, they kept others 'on side' and (3) they worked to the timing and schedule agreed (4) they cleaned up, every single day (5) they worked to a high standard and corrected for any issues, despite my inevitable last minute changes. Wish him and team best success... happy to recommend. Rob

Restoration & Refurbishment- 28 Aug 2018
We had the very intricate loft reconfiguration done with extra big size window installation and full refurb on our recently bought Victorian end of terrace. It was a great experience all along, starting from the quantity surveyor detail level quote provision to the sign off and snagging. I was pleasantly surprised by the attention to detail with what Lux Construction delivered the works, and project manager Jonas professionalism was exceptionally high from my personal experience. Upon such a great experience I have been recommending you to all our neighbours when being asked who did such a perfect job for us. Thank you once again.

Extensions- 8 Oct 2018
Alton and his team at Bluelime have been incredibly helpful and enthusiastic throughout our design and planning process. From the start, Alton took his time to understand our needs and propose several cost-effective ways to improve my home and create more space for my growing family. The design process was completed efficiently and submitted for planning permission, which was granted without a problem. Since then, his team have continued to be helpful and communicative despite my need to delay to the building works due to unfortunate complications with my freeholder.

Plumbing- 24 Sep 2018
Had confirmed I would take a day off for the job. Received a text on the day at the time he was meant to come saying van had broken down and could not come. Then offered to send a friend to do the job. Waste of a day and spent morning running around buying the equipment. If the van did really break down then that’s a fair excuse. Negative experience from my end.
