Extensions- 23 Jul 2024
Alex and the team did a great job. - They worked with me to bring my design concept to reality - worked through amendments and issues as they arose - came up with ideas for improvements - were quick, punctual and could be trusted - very responsive over messaging which helps on a live project. Really happy with the end result. Good price for the work done. Highly recommend.

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.

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.

We needed a rear extension built with an internal courtyard. From day one when we first contacted Mert to get a quote he was professional and easy to talk to. His quote was good value for money. During the job he and his team were approachable, careful with our property and always easy to talk to and answer questions we had. The work Mert did was fantastic and our neighbours have already gone on to use him. We will get him back again for more work and highly recommend him.

Painting & Decorating- 6 Oct 2022
Very pleased with our choice. We initially got four quotes from different builders, most of them were terrible at communicating apart from Alfred. He was very easy to work with, responsive and very careful with our brand new house. His team was hard working, tidy and fast. They completely renovated our garden from removal of old decking and gravel to setting up new fences, levelling and turfing the ground. They also removed our old kitchen, partition wall and carpet, as well as did jobs like plastering, building a wall and set up lights and shelves. We’ll surely have him back soon to work on other jobs.

Plastering- 17 Jun 2024
Adam Favor and NOVA Design & Build are a nice bunch of guys and they are reliable/helpful. However, when it came to coving, architrave and flooring, acceptable standards were unfortunately not met. Other specialists had to be brought in to re-do around 20% of the job; namely certain sections of the cornice and door architrave. In the former, a few things were below standard including: 1) not joining the friezes in the correct places, 2) cutting inaccurately, 3) leaving gaps, 4) using silicon as a filler and adhesive. For the door architrave, the wood was misaligned and not glued/nailed properly. The flooring was not laid well because there are huge gaps at times; sometimes at 1 cm. Since the kitchen has been installed, it is too late to take up the floorboards again. The most dubious thing of all in this job was the quote received for decorating which was c. 15k for 47 m2. This included plastering repairs, but ultimately the job got done by someone else to a high standard at 7k.

I recently completed the building of an orangery extension (with skylight) to my semi-detached townhouse in NW London. The extension was to be used as a new kitchen while the existing kitchen converted to a living room. I awarded the contract of building the extension to Anthony and I was pleasantly impressed with the quality of work delivered. Anthony Project Managed the entire process from beginning to end and ensured that all my expectations were surpassed. His hands-on attitude to every detail of the work was quite reassuring. I am glad to say that Anthony and his team are very good professionals and they delivered the project on time and within budget, even going over and beyond the original scope of works in order to ensure that all my latter requests were addressed appropriately.
