Latest review:
RS Building successfully delivered two full back-to-brick refurbishments and a new-build development for us in Greenwich, including demolition and construction of four new dwellings. Their level of workmanship is exceptional, and their attention to detail is second to none. As experienced property developers, we’ve worked with many contractors—but RS Building stand out for their reliability, quality, and professionalism. We have since recommended them to several colleagues, all of whom have been equally impressed. Our only regret is not finding them sooner. We look forward to working with them again on future projects.

Extensions- 23 May 2022
Ceca Developments have done an outstanding work on our side and rear extension project, and we would definitely recommend this company. Firstly, they have offered a really competitive quote for the work and have been very transparent and detailed in regards to how long it will take to complete the project. Sebastjan has been a pleasure to deal with and was very helpful during the project, providing honest and useful recommendations and being available every time we needed anything. All the work has been completed to a very high standard and to the agreed timelines. We did not have to worry about anything during the whole project, which made this a very pleasant experience.

Restoration & Refurbishment- 16 Feb 2018
Adam and his team did a brilliant job! My flat was in very bad condition. They gutted the whole flat and refurbished everything to a very high standard. Work performed included, new boiler and radiators installation, complete refit of bathroom and kitchen including all tiling, plumbing and electrics, new spotlights and wooden flooring throughout, new doors and skirting boards and all painting and decorating. They also arranged for all skips and rubbish clearance. I simply left the keys with Adam and he performed all work with minimum guidance. I would touch base a couple of times every week or when things needed to be discussed. He was happy to purchase most materials and provide receipts. I would highly recommend Adam and will definitely use him again for future work.
Noli Antzara
Rating: 5 out of 5
Extension Builder in Denmark Hill
I’m Noli Antzara, a North London tradesman with 37 years of experience. I started working alongside my father at 18 and have spent my working life developing my craft. My main specialities are tiling, paving and brickwork. I also take on bathroom and kitchen tiling, slabs, garden work, blockwork, extensions and painting. Whether it’s a small repair or a larger project, I give the same care and attention to the finish. I prefer to visit the property, listen to what you want and provide a clear quote before starting. Depending on availability, I can often begin within one or two days. I’m based in North London and can travel approximately 60–70 miles for the right job. I know that inviting a tradesman into your home takes trust. I treat every property with respect, protect the areas I’m working in and keep the space as tidy as the job allows. I communicate clearly, take pride in the details and want you to feel comfortable raising questions along the way. After 37 years, I still care about improving and doing work I’m proud to put my name to. My aim is simple: to deliver a quality finish and leave every customer feeling that their home was in good hands.

Tiling- 6 Oct 2026
I couldn’t recommend Noli highly enough. He was incredibly friendly, professional and reliable from start to finish. His quote was very competitive and included all the materials. After seeing the fantastic job he did on my front garden, I wish I hired him before. His attention to detail and quality were impeccable. I’m genuinely grateful for his excellent service and have no doubt that Noli will be my first and only choice for any future projects. HIGHLY RECOMMENDED!

Extensions- 20 Aug 2016
Fantastic service, Lucas and Darota are an amazing professional team always reliable and our kitchen extension is to an exceptional standard. Darota offers an amazing interior design service. The builders have been punctual, worked really hard and when we have come home from work the house is always tidy so we don't even feel the house is being renovated. We offered LD Property services more work after our kitchen extension/complete refurbishment to include a complete renovation of all our home including garden and driveway. The project has been managed brilliantly as we work full time this has been really helpful.
