House Extensions in Leeds
Rear, side and wrap-around extensions with first-class finishing
House Extensions by BMK Joinery & Building
An extension is one of the best ways to gain living space without moving. BMK Joinery & Building Ltd handles the whole build, from groundworks, brickwork and roofing to bi-fold doors, roof windows and the internal joinery that finishes the room. Having joiners and builders in one team means the structure and the finish are planned together.
With over 22 years in the trade we know how to make a new extension sit naturally with the existing house, matching brick, roof tiles and window styles so the join is barely noticeable. Customers across Leeds highlight our reliability, tidy working and clear communication.

House Extensions questions answered
Do I need planning permission?
Many single storey extensions fall under permitted development. Larger or two storey builds usually need approval. We talk you through it at your free quote.
How long will it take?
A typical single storey extension takes around 8 to 12 weeks from start on site. We give you a realistic programme before work begins.
Will you finish the inside as well?
Yes. As joiners as well as builders we fit doors, skirting, architraves, flooring and fitted units so the room is ready to use.
