GS Renovation installs steel beams and RSJs across Enfield, from the 1930s semi-detached houses around Trent Park to the interwar suburban homes of Southgate and Palmers Green. With over 30 years of experience across EN1, EN2, EN3, N9, N13, N14 and N21, we remove load-bearing walls safely and finish to building control standards.
Steel beam knock-throughs in Enfield homes
The commonest steel job in Enfield opens up the ground floor of an interwar semi, taking out the wall between the front reception and the middle room, or between the kitchen and dining room, to create one bright living space. Every beam is sized by a structural engineer to carry the floor and often a chimney breast above, then set to bear onto concrete padstones at each end so the load transfers cleanly into the existing brickwork.
Before any brick comes down we install temporary props, or Acrow supports on needles, to hold the structure while we work. Demolition is staged and controlled, dust is managed in your occupied home, and the finished beam is fire-protected and boxed in. Enfield Council building control inspects the beam at key stages and issues the completion certificate that protects the value of your house.
Party wall steelwork in Enfield semis
Because so much of Enfield is 1930s semi-detached and terraced stock, the wall or chimney stack you want to alter often sits on or against the shared party wall with next door. Where that is the case, the Party Wall etc. Act 1996 applies and your neighbour must be served the correct notice, usually two months before work starts. We help you understand who needs notifying and coordinate around the agreed surveyor's award.
The generous plots common in EN2 and N14 mean many owners combine a steel knock-through with a rear opening for bifold doors, which adds a second beam and sometimes goalposts framing the opening. We plan the propping sequence so both beams go in without overloading the party wall, keep the works watertight throughout, and hand over clean building control sign-off for the whole structural package.
When one beam is not enough
Not every opening is solved by a single steel. Where a wall comes out on the ground floor and a wall above runs in another direction, load arrives from two directions and the engineer may specify a pair of beams, or a main beam with a second trimming into it on a bolted connection. Where there is no masonry left to bear onto at one end, the answer is a goalpost frame: two posts on base plates carrying the beam, with the posts taken down to a pad below floor level.
This comes up in the larger Enfield houses around Grange Park and out past Forty Hall, where owners open the back of the house and remove an internal wall in the same project. Two openings at right angles are designed together rather than one after the other, and the connection between the beams matters as much as the beams. It affects the programme too, since a frame needs its foundations formed and cured before anything is lifted.
