Opening up a home is often the change that makes the biggest difference. Removing the wall between kitchen and dining room, widening an opening for bi-fold doors or taking out a chimney breast can completely change how a house feels.

When a wall is load-bearing, it has to be done properly. A structural engineer designs the steel beam and supports, Building Control approves and inspects the work, and we prop the house safely while the beam goes in. Structural work is at the heart of most extensions and kitchen renovations we build.

Removing a load-bearing wall

We start by confirming whether the wall is load-bearing and what it supports. The engineer then calculates the beam size, padstones and any posts. On the day, we install temporary props, remove the wall, fit the steel, pack it tight and inspect with Building Control before making good with plasterboard and skim.

Chimney breast removal

Removing a chimney breast frees up valuable space, but whatever is above must be supported. That usually means steel beams or gallows brackets, depending on what the engineer and Building Control will accept. If the chimney is shared with a neighbour, the Party Wall Act applies. Read party wall agreements explained.

Structural alterations: common questions

More answers on our FAQ page.

How do I know if a wall is load-bearing?

Clues include walls running across floor joists, walls continuing above on the next floor and thick masonry walls. Never rely on guesswork: we check, and a structural engineer confirms.

Do I need Building Regulations approval to remove a wall?

Yes, if the wall is load-bearing. The steel beam needs a structural engineer's design and Building Control approval and inspection.

How long does a knock-through take?

The structural work for a typical kitchen-diner knock-through takes a few days on site, plus plastering and making good afterwards.
