Knock-throughs & new openings in Wilmslow

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

From 1930s semis off Altrincham Road to substantial detached homes around Fulshaw Park and Alderley Edge, Wilmslow projects are often about opening the back of the house to the garden — goalpost frames for wide sliders are a regular job here.

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 Wilmslow: your questions answered

Do you cover Wilmslow?

Yes — Wilmslow and the surrounding area are part of our regular patch. Wilmslow falls under Cheshire East building control; most of our Wilmslow jobs are signed off by them or by a registered 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.
