Extensions- 27 Jun 2019
Mike built our extension (20m sq approx.) which involved rerouting a number of waste, soil & rainwater pipes, blocking up an existing window, fitting two new windows, sliding doors and roof lantern and laying a new patio area. He started and finished the work on time and readily coped with adjustments we made to the plans. My wife and I are very pleased with the results. Mike is a willing and able worker with an easy going, genial nature who wants to do a good job. We've asked him to quote for some addition work and I'm happy to recommend him.

Extensions- 8 Oct 2025
Jason and his team have just completed our wraparound extension, and the result has exceeded all expectations. Their workmanship, accuracy, and attention to detail are outstanding, and the whole process was smooth and stress-free. They stuck to timings, kept the budget in mind, and made everything feel effortless. Partway through the build, Jason had to undergo an operation and was signed off for five weeks. Remarkably, nothing was delayed — his team carried the project seamlessly, and with Jason still on site when he was able to be, everything ran perfectly. It’s a real credit to how capable they all are and the consistently high standards they work to. The only negative thing I can say is that we were sad to see them leave – they’ve been such a positive part of our daily lives over the past eight weeks. The finish is exceptional and we’re absolutely over the moon. We couldn’t recommend Jason and his team highly enough.

An extension builder in Winchester 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 Winchester 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 Winchester?

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