Open-plan without the guesswork
Knocking a kitchen and dining room into one, or opening a hallway into a through-lounge, usually means taking out a load-bearing wall and carrying it on a steel beam. We size the steel with a structural engineer, install it safely and make good so you would never know a wall was there.
Steels, chimney breasts and openings
RSJ and goalpost-frame installation, chimney-breast removals with gallows brackets or steel support, wide structural openings for bi-folds, and pad-stones and padplates done correctly. The structural side is where corners get cut by cheaper outfits, and where we do not.
Calcs, controls and clean work
Every job comes with engineer’s calculations and building control sign-off, temporary support (Acrows and needles) where needed, and a tidy site. Where a shared wall is involved we handle the party wall notices too.

Frequently asked questions
How much does removing a load-bearing wall cost?+
Removing a load-bearing wall and installing a steel beam in our area typically runs from around £2,500 to £6,000 depending on span, access and finishing, including engineer’s calculations and making good. Our estimator gives a tailored figure.
Do I need building control or planning?+
Internal structural work rarely needs planning permission, but it does need building control approval and engineer’s calculations, plus a party wall agreement if a shared wall is affected. We handle all of it.
Can you remove a chimney breast?+
Yes, on the ground floor, upper floors or both, supporting what remains above with gallows brackets or steel and signing it off with building control.
Which areas do you cover?+
We cover Cheshunt, Cuffley, Goffs Oak, Enfield, Hoddesdon, Broxbourne, Waltham Cross and across Hertfordshire and North London.
