I have been using HS Construction London for many years ranging from a full house refurbishment to smaller unexpected issues. I have always found them to be reliable and genuine. There are never any hidden surprises in the end. Sunny listens to his customers and also gives decent advice where needed. Their work is of quality and has a long life. I particularly impressed with how they complete the job in a timely manner. All the materials that have been used are of great quality; and it shows. In addition, HSC has many contacts such as architects, suppliers etc which has made my life so much easier. Reasonably priced and with great knowledge, i would certainly use them again.

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.

Extensions- 27 Oct 2022
Jack and all of his team were great from start to finish. Having never had any building work like this done Jackbwas reassuring, punctual and always happy to answer questions. Any issues were communicated promptly and solutions discussed. All of the team were really mindful of keeping mess to a minimum, and always tidied up at the end of each day. Jack also worked directly with building control to help smooth the sign off process. All in all I can't recommend Jack highly enough for anyone looking for a reliable and quality construction job

Landscaping- 16 May 2024
We hired Albion Groundworkers to take on our garden and driveway project. They are a very hardworking bunch of guys who do not slack when it comes to quality! They arrived everyday on time and worked extra to make sure the job was completed in the estimated timeframe. Armir was my main point of contact and he was always there to answer questions and provide advice where necessary. They were very mindful of my neighbours and ensured the site was left clean and tidy before leaving. It is a family run business and they take a lot of pride in their work. I would highly recommend anyone to use them and I have already had so many compliments from family and friends!

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

What experience do you have with similar extensions in High Wycombe?

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