Knock-throughs & new openings in Didsbury & South Manchester

Planning a knock-through in Didsbury & South Manchester? We open up kitchens, dining rooms and through-lounges — engineered, signed off and left ready for plaster.

South Manchester's Victorian and Edwardian semis — Didsbury, West Didsbury, Chorlton and Withington — are classic knock-through territory: two reception rooms into one, or the kitchen opened into the return.

A knock-through joins two rooms into one — most often the kitchen and dining room, or the front and back rooms of a terrace or semi. We also form new doorways and widen existing openings, including large openings in rear walls for bifold or sliding doors.

Knock-throughs & new openings in Didsbury & South Manchester: your questions answered

Do you cover Didsbury & South Manchester?

Yes — Didsbury & South Manchester and the surrounding area are part of our regular patch. Didsbury and Chorlton fall under Manchester City Council building control, or a registered building control approver.

Do I need planning permission for a knock-through?

Usually not for internal walls in a house. You do need Building Regulations approval if the wall is load-bearing, and listed building consent if the property is listed.

Can you form an opening for bifold doors?

Yes. We install the steel lintel or goalpost frame the engineer specifies and leave the structural opening sized to your door supplier's dimensions.

Will a knock-through make a lot of dust?

Cutting masonry is dusty, so the work area is sheeted off, dust extraction is used on cutting tools and the site is cleaned at the end of each day.
