Extension Builder in Pinner
My Dad and I set up the company at the beginning of this year with ambition of building our own company, instead of working for others. We work in Hertfordshire, North London, Essex and Lower Bedfordshire. My dad has worked in construction for over 30 years, doing surveying for main contractors, as well as his own property development projects. I have now completed my degree apprenticeship in construction quantity surveying achieving a building science second class honors. I have also ran my own jobs for a main contractor in London and surrounding areas worth up to £4 million. Our lads on the tools all have CSCS cards, and have achieved the relevant carpentry qualifications. We specialize in bespoke garden rooms with our in house labor, and build extensions, refurbs, conversions, and new builds.

Extensions- 11 May 2018
After a rogue builder left me with 18 (eighteen) structural issues. Lez and his crew came in transformed my failed extension into a masterpiece. All aspects of the job was done to the highest quality and utmost care and attention to detail was shown to building control needs. They cleaned up after every day and made sure the house was habitable, as I had to live there. Every aspect of the build, from the carpentry, plastering and tiling was first class and their recommend electrician and plumbers were from the same stock. Total professionals. My only regret is that I did not use this builder the first time. The prices were reasonable and even building control had good word to say about their work. Thanks Lez

Landscaping- 7 May 2026
“We recently had our landscaping redone along with new turf installation, and the results were excellent. The team was professional, punctual, and paid great attention to detail from start to finish. They completely transformed the garden, leaving everything neat, tidy, and looking amazing. The new turf was laid perfectly and has already made such a difference to the overall appearance of the space. Communication throughout the project was clear and friendly, and the workmanship was top quality. Highly recommend to anyone looking for reliable and skilled landscapers.”

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

An extension builder in Pinner 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 Pinner?

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