House Extensions · Manchester (M-postcodes)
Specialist house extensions for Manchester homeowners
We design and build single, double-storey and wrap-around house extensions across Manchester — Chorlton, Didsbury, Withington, Whalley Range, Levenshulme and surrounding M-postcodes. Most of our city work is on Victorian and Edwardian terraces where opening up the back of the house onto the garden transforms how the family lives.
Manchester's housing stock is dominated by 9-inch solid brick walls, suspended timber ground floors and lath-and-plaster ceilings — none of which behave the way a modern cavity-walled semi does when you cut a steel into them. We've been working on Manchester terraces for over 25 years and have the structural calcs, brick matching and Building Control routine down.

Don't just take our word for it. Hear directly from the homeowners and businesses who've trusted us with their projects.
"Lee was doing some work that looked great for my neighbour and so I asked him to come and do some pointing and drain repairs for me. I was really happy with the workmanship, the price and the punctuality. Lee was not quite happy with the match of colour of some bricks he was going to use around my drain — he went off to get a better match! Great work overall."

"Very pleased with the work Lee and his team have done for us, removing an external door and installing a window in its place and plastering. They've done an excellent job. They go above and beyond to please you. I would highly recommend them to anybody."

"We used Boardman Builders to repurpose our old garage — they reduced the length to give us a bigger drive, got rid of the up and over door and bricked up the space, installed a new roof, entrance door and electrics. I love my new shed! Very happy with all the quality of work."

"I couldn't be happier with the Boardman Building Co. They have done a great job on my 3-storey extension and come up with some great ideas which I hadn't considered. Highly recommend for any project."

"Boardman building completed a double step outside my rear bi-folding doors. The quality of work was fantastic. Very easy to work with — Lee communicated about everything from start to finish. His knowledge of the trade was impressive and his organisation on the job was immaculate."
