GS Renovation installs RSJs and steel beams across Hampstead, from period cottages near the Heath to the substantial Victorian villas of NW3. With over 30 years removing load-bearing walls in bay-fronted terraces, we manage the engineering, the propping and the building control sign-off so your knock-through is safe, level and properly certified.
Steel beams for Hampstead terraces
Most steel work in Hampstead involves opening up the rear closet wing or taking out the wall between the two reception rooms of a Victorian terrace. Because those walls carry the floors and often a chimney stack above, a structural engineer sizes the beam to the actual loads. We bear each end onto a concrete padstone, calculating the spread so the masonry below the bearing is not overstressed once the wall comes out.
Before any brick is touched we install temporary props and needles to hold the structure, then remove the wall in careful stages. On the tighter plots common near the village, access is limited, so we plan how the steel is craned or carried in, protect the period floors and staircase, and keep the site clean while the building is still lived in throughout the works.
Party wall notices in NW3
The dividing walls and chimney breasts in a Hampstead terrace usually sit within a shared party wall, so cutting a beam bearing into that wall triggers the Party Wall Act. you serve the correct notice on the neighbouring owner in good time, and where a surveyor and schedule of condition are needed we point you to the right process before work starts, avoiding the disputes that hold up so many NW3 projects.
Every beam we fit is inspected and signed off under building regulations by Camden Council building control or an approved inspector, not planning permission, since removing an internal wall is a structural matter rather than a planning one. You receive the engineer's calculations, the padstone details and the completion certificate, which protects the value of the property and reassures any future buyer or surveyor across the borough.
Coordinating the specialists on steelwork
A steel installation in NW3 pulls in people who do not work for us and whose diaries do not bend. The structural engineer is appointed at the start. The fabricator cuts, drills and often galvanises to the engineer's schedule, and that lead time is fixed. Building control or an approved inspector books separately. Where the steel is heavy, a lifting contractor or a mechanical hoist may be needed on one specific day.
Our part is making those diaries meet. The engineer's design must be final before fabrication starts, because a hole drilled in the wrong place cannot be moved on site. Propping has to be up before the delivery lands. And the inspection needs to happen while the bearings are open, which pins the plasterer's start date. We plan backwards from the steel delivery, since that is the least flexible item in the programme. Where any of those dates slip, we would rather move the whole sequence than start a stage the previous one has not properly finished.
