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.

Civico did a number of jobs for me, including two bathroom renovations where they installed a Japanese toilet and a hydromassage bath, as well as underfloor heating, electrical work and some really nice tiling. They were always reliable and easy to deal with, and the standard of the work was very good. Even after everything was finished, they were happy to come back and help with small things when needed, without charging extra. I would definitely recommend them for bathroom work, electrical jobs and tiling.

Shumon and his team did plastering, painting and decorating and they built me a fireplace and fitted in a fire. I would highly recommend him - he is absolutely brilliant and did a great job - they take a lot of pride in what they do, very trustworthy, and I am looking to have them back about Christmas time to do some bathroom work. They are very good value for money.

I had the pleasure of working with Romeo and his team on my kitchen renovation, and I couldn't be happier with the results! From start to finish, his work was great. The kitchen looks fantastic, and they even finished the project ahead of schedule! Romeo and his team were very professional, always on time, and always kept me updated on the progress of the project. They also kept the flat clean and tidy every night, which made it much easier to live in the flat while the project was being done. I highly recommend them to anyone looking for a kitchen renovation!

Asen did an incredible job! In just under 4 weeks he managed to assemble a team and complete renovation on a 2 bed flat including: * Full rewiring, new lights, updating and adding sockets * Fixing rotten and uneven subfloor and levelling the whole house * Wood flooring throughout - done excellently with no thresholds * New boiler and all new radiators * Built a pocket door at the porch to stop our kitties from escaping * Tiled the fireplace * Skirting, decorating and repainting the entire flat * Dealt with gutting the place and arranging pickup of rubish The place looks and feels amazing and everything works! Asen was good on the price, kept to the (very tight) timelines, great communication throughout and overall very professional and friendly! Pics shows after and during the work, ignore the moving boxes.
