Extensions- 10 Jun 2020
We had a one bedroom lower ground floor garden flat and did a side return and extension into the garden. The flat is in West Kensington area. We also did a full internal refurbishment and moved just about every wall, moved boiler, new Porcellanosa bathroom, new kitchen, new flooring throughout, a large bi-fold door in the living room to the garden. Chris and RAS Construction have been the best possible builders for this project. They were simply amazing. What we loved most about them: - speedy and no-nonsense communication (very important for us) - friendly and approachable - super professional and friendly team - very quick and helpful when a problem arose due to some architect's error - good aftercare - stayed in quoted budget - offered improvements and reasonable quotes - very easy to work with - only asked for partial payment every few weeks after job had moved along reflecting the amount charged This review was written about 8 months after the project was completed and we are still very happy with the quality. I would not hesitate to recommend Chris and his team at anytime. You hear so much about bad builders, we have been very lucky that we have found him. We are now house hunting for a bigger place and will re-engage with them for the next project.

Extension Builder in Kilburn
I am a construction professional with a well-rounded background that spans from domestic refurbishments to super-prime residential projects. I began my career working on smaller projects such as bathroom and kitchen refurbishments, loft conversions, and house extensions, gaining hands-on experience in every stage of the build process. Over time, I progressed into managing and delivering high-end and luxury residential refurbishments, where precision, detail, and client expectations are at the highest level. My blend of architectural training and on-site experience allows me to approach projects with both design sensitivity and practical efficiency. I am skilled in budget management, construction programming with Powerproject, and the use of digital tools including Bluebeam, AutoCAD, and Revit to coordinate and deliver work to the highest standards. Whether working on a bespoke renovation or a large-scale development, I am committed to providing quality workmanship and a seamless client experience.

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.

Restoration & Refurbishment- 28 Dec 2015
I did quite a bit of research before choosing Battersea Builders. They didn’t come in with the cheapest quote but I never base my choice on price alone. And it wasn’t miles above the other quotes I got. Instead, I chose them because they ticked a lot of boxes including a) good independent reviews, b) a dedicated PM, c) qualifications, d) quick responses, e) a decent website etc. Overall, they did a fantastic job. The quality of the work and finish is really good. The PM, Tommy, was really helpful throughout and the team was very polite and conscientious. They were also on site every day as promised and didn’t play that old builders trick of getting the job and then going offsite to secure another job elsewhere (resulting in the deadline being missed). Was it perfect? No, but then not many projects are. I have a few minor comments including the fact there was a misunderstanding about the quality of bathroom cupboard I needed so the original quote was insufficient and costs had to be increased half way through the project. Despite this issue, Tommy did his best to keep the extra costs down. One other niggle was that I asked them to keep all the manuals and instructions for all the fittings but they threw them out. Not a big deal but quite annoying. Overall, it wasn’t cheap but I would use them again because the work was done to a high standard and the team were a pleasure to work with.
