Steve Scarrot built my double extension and I can honestly say, wow what a great job. I can’t say a bad word about it. Steves workmanship and knowledge on the building game is second to non. His hard work and dedication to work is first class. He was prompt, never late and did exactly what he said he was going to do. His quality of work was exceptional and he never tried to cut any corners he was first class all the way. An absolute professional and a credit to the industry and I’d happily have him work for me again.

Built4u Developments have been a pleasure to deal with throughout the entire process of building our new home in leeds. William and his team are extremely professional, friendly and genuine people. They are punctual, reliable and proved to truly care about the quality of work that they produce. William has always been available for any queries we have had about the building process, and has been transparent about each stage of of construction throughout. William is extremely skilled at what he does, no task proved too big for him or his team, especially after seeing our stone and brick feature wall he told us to leave with him, which is a truly remarkable piece of art that he has built, which i am over the moon with, He also came up with several innovative suggestions throughout the house build process in order to improve quality of works, he has been brilliant. I would highly recommend Built4u Developments ltd for any renovation work, new build or feature work - we are so pleased that we decided to go with them out of a long list of construction companies in West Yorkshire.

After a frustrating time dealing with the council, Oliver at Northern Planning & Design met with me and quickly produced exactly what was needed for the planning application. I wish I had approached him sooner but but had mistakenly thought the job would be too small for anyone to be interested in.

Bear Construction (Yorkshire) LTD
No reviews yet
Extension Builder in Knottingley
At Bear Construction, we pride ourselves on our commitment to quality, integrity, and excellence in all areas of construction; Founded by Ashley Fellows, a Quantity Surveyor by trade. Ash decided against attending university as the obvious route to qualification and rather completed an apprenticeship after completing his A Levels. By going down this route, this provided Ash with not only the knowledge of how to carry out the role, but also the valuable opportunity to work on site when possible to grow as a QS and understand the construction element, rather than just from an office perspective! So, Why call it BEAR? This was a family nickname given to Ash from a young age and has symbolic meaning reflected in the company's core values. It also stands for what we do: Building, Extensions And Refurbs! Bear Construction offers a comprehensive range of construction services, catering to diverse needs across residential, commercial, and industrial sectors. Whether it's extensions, renovations, or maintenance projects, our team of skilled professionals is equipped to handle every aspect with precision and efficiency. Should you wish to consider us for your upcoming project, please don’t hesitate to contact us!

What experience do you have with similar extensions in Knottingley?

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