Poynts Works Ltd
Rating: 5 out of 5
Extension Builder in Croydon
I'm an ARB Registered Architect with 18 years' experience designing residential extensions, renovations and conversions across London. I work directly with homeowners from the earliest ideas through planning permission, Building Regulations and, where required, construction on site. Every project begins by understanding how you want to live. Using sketches, 3D models and visualisations, we can explore different options together before you commit to building work, giving you confidence that the design is right for your home and your budget. Once the design is agreed, I prepare the detailed technical information needed for construction and remain closely involved throughout the build, helping resolve questions on site and ensuring the original design intent is delivered. If you're considering extending or renovating your home, I'd be happy to arrange a free initial conversation to discuss your ideas, the likely planning implications and the next steps.

Extensions- 18 Oct 2017
I asked Prohaus to undertake a ground floor side return and rear extension as part of the refurbishment of my flat in Putney. I have used many builders before on development projects but was especially impressed with Naz and his team on this build. It was the first time I used them and won’t be the last. Naz was great to work with, the whole build went smoothly and he always had a positive attitude and solution to any unexpected issue. The build came in on time and budget which was very impressive in itself. All in all I would highly recommend him.

My house was old and its condition was poor. Much were needed to be fix. The original kitchen layout were also inconvenience to my wife. I need to have all these changed under limited time. This builders have a team of specialists on almost every aspect. They gave me variety on the layout design and choose of materials. This saved me money, time and tons of trouble to find difference contractors. The after service and their respond time are very good too. I hope by sharing my happy experience can save your money and trouble to find a good contractor.

Conversions - General- 11 Sep 2026
I am delighted with my new cast iron Victorian air bricks with grills! Jacek took the old ones out and inserted the new ones. The job is extremely neat and the area left completely immaculately. A few neighbours have taken his number for more work. You will find Jacek extremely polite and amiable, professional, hard working and very knowledgeable about his particular trade. His price was competitive and I would have no hesitation in recommending him. I will be hiring again for other structural work. A great professional find!!

Tiling- 10 May 2019
As per the previous reviewer I don't usually hire tradesmen when there is only limited feedback, but given the glowing report I took the risk. And it proved to be a great decision. Astrit was great - clear communication, arrived when he said he would, sought our opinions on the key decisions and gave some great advice, before ultimately doing a great job for a reasonable price. A pleasure to deal with and will hire again for any future tiling work. Thanks Astrit.

What qualifications and experience do you have as an extension builder in Croydon?

An extension builder in Croydon should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Croydon extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Croydon?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Croydon extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?
