GS Renovation installs RSJs and structural steel in Harlow homes, from a single opening between two rooms to a beam carrying a rear wall. A structural engineer we appoint sizes the section and issues the calculations, and we build to them. GS Renovation is a contractor and never produces structural calculations itself. The company is fully insured, and our founder has over 30 years of hands on experience.
Steel beams in Harlow's terraced houses
A steel beam in a Harlow terrace is designed around the party walls it bears onto. Census 2021 counted 37,856 households in Harlow, of which 17,166 were in terraced houses, against 5,381,432 out of 23,436,085 households across England. The Harlow Local Development Plan records over 35,800 dwellings in the district and attributes that higher than average proportion of terraced properties to the principles of the original master plan for Harlow. Terraced geometry sets the engineering question, because the beam ends land on structures shared with a neighbour.
The engineer establishes what the wall carries and sizes the section, and deflection can govern the design as much as strength does. Where a bearing sits on a party wall, notice under the Party Wall etc. Act 1996 is served before work starts, and the notice period runs its course whether or not your neighbour objects. On site we prop first, form the pockets, seat the beam on its padstones, pack the bearings solid, then strike the props in sequence.
Booking the Harlow Council inspection before the steel is covered
Harlow Council runs its own building control service, so the inspection is arranged with the council unless you appoint a private approver. Its officers can be reached on 01279 446853 or at building.control@harlow.gov.uk, at the Civic Centre, The Water Gardens, College Square, Harlow CM20 1WG. The council asks for site inspections to be booked through the free Local Authority Building Control app, or by phone. If you need a next day inspection, you have to book it by 5pm the day before.
That 5pm cut off belongs in the programme. Bearings, padstones and packing have to be seen while they are still exposed, so the visit is arranged around the day the steel goes in rather than after the plasterboard. We hold the sequence: steel in, inspection booked, bearings open for the officer, then fire protection and finishes. The beam then needs its encasement to give the fire resistance Approved Document B expects, and plasterboard is the standard way of providing it.
Getting the steel into the house
Access decides how a beam reaches the room it will sit in. Harlow Council's Mark Hall North appraisal records that terraced rows there were built with access tunnels through the row, giving pedestrian access from the front to the rear gardens. A tunnel like that is a route to the back of the house without going through it, which changes how steel, spoil and rubble are moved. It is also an opening in the row with a structure over its head, so what it does to the walls either side is a question for the engineer.
The older parts of the town read differently. Harlow Council's Old Harlow appraisal records that the largest area of late Victorian and early Edwardian house building lies east of Harlow, with much of Bury Road and New Road laid out between 1870 and 1901. A house of that period has solid brickwork and shallow footings, so the end reaction from a long beam has to be worked down to the ground. That can mean a reinforced concrete padstone, brick piers, or a new pad formed below floor level.

The GS Renovation Difference in Harlow
An RSJ is a sequencing job as much as a lifting job. GS Renovation appoints the structural engineer, builds to the issued calculations, and never writes them itself. We prop before we cut, keep the bearings open for the building control inspection, then close up and fire protect.
