GS Renovation removes load-bearing walls in Totteridge, where N20 is mostly large detached houses on deep plots rather than paired semis. Wider rooms mean longer spans and heavier steel than a standard suburban knock-through. We appoint the structural engineer, build to the calculations, and take the work through Barnet Council building control to certificate.
Removing a load-bearing wall in a Totteridge detached house
A detached house off Totteridge Lane often has a ground floor five or six metres across with no shared wall to help carry it, so the internal wall you want gone may be doing more work than the same wall in a semi. We start with a structural engineer's assessment of what sits above: floor joists, the wall on the first floor, and in many of these houses a purlin strut landing directly on the line you are opening up. Nothing comes down before that is established.
Longer spans push the beam size up quickly. Where a semi might take a 152 or 203 section, a wide Totteridge opening can call for a 254 or deeper, and the padstone at each end has to spread a far heavier point load into masonry that was never designed for it. We check what sits under the bearing before we cut, because a beam end landing over a soft spot in an old footing simply moves the problem downwards. Props go in first, the wall comes out in stages, then the steel is seated and packed tight.
Building control and conservation area consent in N20
Taking out an internal load-bearing wall is a Building Regulations matter, so Barnet Council building control or an approved inspector reviews the engineer's calculations and inspects the bearings before they are plastered over. Planning permission is not involved. That changes only if the external fabric is touched, and in the Totteridge Village conservation area even a small change to a window opening or a section of demolition visible from the street can need conservation area consent, which is a separate application to the planning department.
The other N20 check is whether the house is listed or sits within the curtilage of a listed building. Some of the older properties along Totteridge Village and around the Green are, and we never assume either way; the address is checked against the list before any internal opening is designed, because listed building consent reaches internal fabric as well as the outside. Detached houses here rarely raise party wall questions on an internal beam, since the nearest neighbour is usually a garden's width away.
- Party Wall Act notices where the opening reaches a shared wall
- RSJ and steel beam installation to the approved design
- Building control notification and inspection sign-off
- Joist ends supported where the wall carried the floor above
- Making good, plastering and skirting reinstatement
The GS Renovation Difference in Totteridge
Totteridge openings are wider than the suburban average, and a wide opening is where guesswork shows. GS Renovation appoints the structural engineer, builds to the calculations, checks the bearings before they are hidden and manages Barnet building control through to certificate. We also settle the listed and conservation position before design rather than after. Founder-led, with more than 30 years of hands-on structural experience.
