Steel in Totteridge is heavier than steel in most of Barnet, because the rooms are wider and the houses are detached with no neighbouring structure to share the load. GS Renovation installs beams to the structural engineer's calculations, plans how the section physically reaches the opening, and gets every bearing inspected by Barnet Council building control.
Sizing and seating steel in a detached N20 house
The beam is sized by the engineer for the span, the load path and the deflection limit, not by what fitted in the last house. On a wide Totteridge opening that often produces a section a person cannot carry, which changes how the job is planned rather than whether it is possible. Sometimes the answer is two lighter beams bolted together as a flitch arrangement once they are in the room, sometimes it is a single section craned over the roof, and occasionally it is a column part way along to shorten the span.
Bearings deserve as much attention as the beam. A heavier section concentrates a much larger point load into a small area of brickwork, so the padstone is designed rather than picked off a shelf, and we check what is beneath it down to the footing before cutting the pocket. Temporary propping goes in on both sides of the wall and stays until the steel is seated, packed with slate or dry pack and the load has properly transferred. Only then do the props come out, and in sequence.
Getting steel onto the plot past protected trees
This is the part that catches people out in Totteridge. Many of these houses sit behind long driveways under mature canopies, and a great many of those trees carry a tree preservation order, with everything in the Totteridge Village conservation area protected as well. A lorry or a hiab parked over the root protection area of a protected tree compacts the soil and damages it, which is an offence you do not want attached to your build. Ground protection boards or a different access route are planned in advance.
Practically, that means we walk the access before ordering, measure the gate, the turning circle and any overhanging limbs, and agree where the steel lands and where it is stored. Crane or hiab lifts get booked around it. Where nothing can reach the back of the house, the section is broken into liftable pieces to the engineer's design and assembled in place. It is a boring conversation to have early and an expensive one to have on delivery day, with a lorry on Totteridge Lane and nowhere for the steel to go.

Why Totteridge Homeowners Choose GS Renovation
Beams for Totteridge houses are big, and big beams fail on logistics as often as on engineering. GS Renovation checks access, tree root protection and lifting arrangements before the steel is ordered, builds strictly to the engineer's calculations, and has Barnet building control inspect every bearing before it is covered. One founder-led team, more than 30 years of hands-on structural work, and the certificate at the end.
- Beams boxed and fire protected to the approved detail
- Restricted London access planned before the steel arrives
- Free follow-up visit after completion if anything needs attention
- Itemised pricing, so you can see what every stage costs
- Clean, tidy and reliable tradespeople
- Temporary propping in place before anything is cut
