Tiling- 21 Jan 2017
Great job from Mateusz and his team! They did great job in our kitchen. Tiling,2 splashbacks and cooker hood were all installed within one day and that includes them cleaning the place.

Conversions - General- 25 Jul 2026
Would highly recommend - the process and communication was incredible from start to finish. Sukh was really helpful and thorough, helping us understand the whole process of our renovation and breakdown of the costs, talking through our floor plans and analysing the videos we sent. Really appreciated the flexibility and transparency to work within our budget, time scale and adhering to property regulations. Work was done excellently and promptly, within agreed upon timeline and all furniture was covered. The crew was very considerate with cleaning up after and very kindly handled all the disposal of material for us.

An extension builder in Marlow 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 Marlow 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 Marlow?

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

How long will the extension take to complete?
