Extensions- 3 Feb 2021
Gavin built me an outhouse at the bottom of the garden. The work was tidy and efficient and the result just what we agreed. This involved brickwork, carpentry and electrics, and all was done to a good standard and in a reasonable timeframe, even despite the snow! I would recommend Gavin to do this sort of work and would use him again if needed.

Michaels team fully renovated my kitchen, from installing underfloor heating, tiling the floor, electrics, fitting new cabinets, integrating kitchen appliances and everything between. Impressed with their work, I also asked them to build a bespoke shelving unit with hidden storage to my living room. Additionally, they sanded my old pinewood floor and stairs. Their communication was great throughout the project. Everything was completed on time, to a high standard and without any hidden costs. I would hire them again without hesitation.

Carpentry- 29 Jan 2026
I contacted Ekland and his brother Bes for some light refurbishment. I was so impressed with the work and speed that they ended up doing all the works I intended to do. Starting with latex screed, flooring using LVT system, architraves and skirting boards, installation of 9x heavy duty fire doors, carpets in 2x bedrooms and finally decoration. Prices were very reasonable considering the time and effort they put into installation but not only that, as I am a first time buyer they advised me on design as I didn’t really know where to start. They are honest and reliable, where I tried to save money they said it was not the right thing to do and took additional hours to make something right without a hidden extra. They turn up at 8am everyday and so easy to work with, I left them the keys to my flat and I didn’t need to check in on them at all. If you are thinking to do any refurbishment and are either hesitant or not knowing where to start these are your guys. 5* to Vukaj and thank you!

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

An extension builder in Lee 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 Lee 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 Lee?

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

How long will the extension take to complete?
