Side return extension steels in Barking: how it works
Our side return extension steels service in Barking covers everything from the first visit to the completion paperwork. Our coverage runs across London, so nearby villages are included too. Postcode districts we cover here include E6, E12, E20, IG1 and IG3.
Many Victorian and Edwardian terraces have a narrow back wing, often called an outrigger, with a strip of yard down one side. Infilling that strip turns a galley kitchen into a wide family room, but the outrigger's side wall usually holds up a bathroom or bedroom above, so it has to be replaced with steel.
Things to plan for
- Planning rules for side return infills depend on the house and its location, and some need a full planning application rather than relying on permitted development. The steel design forms part of the building regulations approval either way.
- Glazed roofs over side returns are usually made to measure and need an edge that stays straight and level. The engineer may set a stiffer limit on how far the steel can deflect so the glazing is not stressed once loaded.
- Propping a side return is awkward because space in a narrow kitchen is tight and the infill side is often open ground. Props outside may stand on temporary pads or boards, set so they do not sink or shift in wet weather.
- Fitting the steel frame for a side return usually takes a few working days on site, depending on how many beams and columns there are. It is scheduled with the builder so the new space can be roofed and weathertight soon after the old wall comes down.
- Bathrooms above outriggers are common, and their floors carry baths, tiles and water. The engineer allows for those loads, and any soil pipe or waste running down the side wall is rerouted before the wall comes out.
What happens, step by step
Look and measure
We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building control and neighbours in Barking
For Barking, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Local questions answered
Can I stay at home while the work is done in Barking?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
Can you work on older or listed homes in Barking?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
Do I need a party wall agreement for a side return extension?
In England and Wales it is very likely. Building on or near the boundary, excavating close to the neighbour's foundations or cutting into a shared wall can all be notifiable under the Party Wall etc. Act 1996. Notices are arranged through a party wall surveyor on your behalf, and we do not give legal advice.
How long does it take to fit side return steels?
Most side return steel frames take two to five working days on site, depending on the number of beams and columns and how easy access is. That covers propping, removing the old side wall, fitting the steels and packing them. Fire protection and finishes follow afterwards.
Can the outrigger wall be removed without affecting the bathroom above?
Yes, when it is properly propped and replaced with steel designed for the load. The floor and wall above are supported throughout, and the bathroom stays usable in most cases. Waste pipes or soil stacks on the wall being removed are rerouted first so nothing is disturbed when it comes down.
