Restoration & Refurbishment- 26 Jun 2022
Tommy was a wonderful perfectionist and has done beautiful work in our stairway and hallway which had needed refurbishment for a very long time. It feels brand new.

Friendly and accommodating, we will be hiring again for more jobs in the future, undoubtedly. Thank you.

When I was looking for quotes, Lukasz was the only builder who provided a fully detailed breakdown. From the start, he was professional and punctual, arriving exactly on time for our first meeting. He offered great recommendations on the best ways to approach the refurbishment and was flexible enough to let me source my own materials. Most importantly, he provides a warranty which he has already honored to fix a minor fault from another professional. It has been a pleasure trusting Lukasz and his team with my full house renovation.

Extensions- 19 Jul 2021
Jitender/Tinku and his team were excellent from the first time we met. They provided us with ideas to better our layouts, helped with sourcing a number items and put us in contact with suppliers which helped us achieve more competitive prices. I was kept updated with the progress regularly and most importantly the project was completed on time and within budget. Shah Builders take real pride in their work and it shows in the finished product. We are very pleased with the outcome of the project and have recommended Shah Builders to friends and family.

Groundwork & Foundations- 7 Feb 2026
Oli carried out the groundworks and demolition at my property and was on site every day with his crew, fully committed and hands-on throughout the job. I am an architect, and this was work on my own home, so my expectations were high. Oli met those expectations fully. He has a strong knowledge of groundworks and demolition, works carefully and methodically, and you can tell he genuinely enjoys what he does and takes real satisfaction in delivering the work exactly as required. He was always in a good mood, easy to communicate with, and a pleasure to have on site. I enjoyed discussing the project and hearing about other jobs he has completed over his 23 years of experience, which clearly shows in the quality of his work. I would highly recommend Oli for any groundworks or demolition works.

What to ask a Stevenage extension builder before hiring?

Before hiring an extension builder in Stevenage or extension building company in Stevenage, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Stevenage 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 Stevenage 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 Stevenage?

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

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Stevenage extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
