Extensions- 6 Aug 2022
Majid has been great in producing drawings for our rear extension. He's also helped explain the whole build process to us from design, building inspection, and building. We received our drawings in under 10 days from the initial consultation and site visit. Majid was accomodating and was able to visit the site on weekends for the initial consultation. Always a pleasure to deal with and has been easy to reach over the phone or email. Would highly recommend Maji and MYD Studio London to anyone looking for an architect.

Bricklaying- 1 May 2026
I needed a shed done and Ranjit and the team provided a competitive quote and explained everything they would do. They arrived on time for all meetings and when the work started, worked solid every day, completing the work in good time. Shed was built to a good standard and the quality of work was very good. They tried to keep things clean and tidy and once finished left the garden clean of rubble. I would definitely recommend them to anyone looking to build a shed or similar.

Peter was the on-site foreman on our complete house renovation, which took just over a year. This included an additional ensuite pod bedroom in the roof and a side-return and extension to the kitchen. Peter was totally reliable throughout the project and thoroughly professional. Throughout this time we were living in the house with the children. He was always on time, managed the on-site team well and communicated clearly with us. His workmanship is high quality and he was also a stickler for checking the work of others and getting it updated if it wasn’t up to scratch. I have no hesitation in recommending Peter.

Fencing- 13 Mar 2026
We hired Bawa to install new fencing, and he did a fantastic job from start to finish. You can immediately tell he’s an all-rounder who understands construction very well. The work was carried out efficiently and to a high standard. Bawa has a great attitude, is very hard-working, and clearly takes pride in what he does. Communication was easy throughout, and the whole process felt smooth and professional. It was a real pleasure having Bawa work for us, and I wouldn’t hesitate to recommend him.

Bricklaying- 25 Aug 2024
AVOID. Ernie incorrectly installed my drains under my house which has caused awful smells and sewage to leak under my house causing long term damage to my foundations Three professional drainage company’s have put a camera to see a Dropped pipe from new to old house. They have identified a connection that was never appropriate. Unfortunately, Ernie after being given many opportunities does not accept any responsibility. He is not an expert at all trades so be careful. I’ve asked him to help put right by exposing the floor which has Underfloor Heating. This has now cost me tens of £000s. My fault for not using a professional team at the beginning of my project.

Extensions- 4 Jan 2026
I hired Amrit based on positive reviews, but my experience was extremely poor. The work showed all the signs of a cowboy builder. I’m sharing this to help others avoid the stress, delays, and financial risk I went through. 1: No Respect for Contract or Deadlines Contract deadline was 15th September, which he completely missed. Despite delays, he demanded money almost daily. When I referred him to the payment and work schedule he signed, his response was: “I didn’t read it, I just signed it.” 2: Dangerous and Unprofessional Working Practices Brought in unqualified workers, many of whom could not speak basic English. He ignored safety standards throughout the project and wanted to use the same unqualified workers for gas work, which is extremely dangerous. When I objected, his response was: “Don’t worry, you will get a new house if it blows up as you have insurance.” 3: Work failed multiple building control inspections. He eventually refused to cooperate with the building inspector.

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

An extension builder in Warlingham 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?

What experience do you have with similar extensions in Warlingham?

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 Warlingham extension builder’s ability to deliver a result that meets your expectations.
