About our side return extension steels service in Boston
For homes in Boston and the PE21 district, we handle side return extension steels from survey to sign-off. We also cover the surrounding towns and villages in Lincolnshire. The beam is sized by a structural engineer and inspected before it is boxed in.
Side returns tend to need more steel than a straight rear extension: a long beam on the old wall line, often a second beam across the back of the main house, and columns where they meet. We arrange the design, approvals and party wall notices through a surveyor, and fit the steel frame in step with the build.
Key points for your project
- 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.
- The side wall of a typical outrigger carries the first-floor wall above it, and sometimes the rear wing's roof and the joists of the room over the kitchen. That is why taking it out calls for a beam along its full length.
- Side passages often carry the house drains and rainwater pipes from the outrigger roof. Manholes and pipe runs are located early, and a shared or public sewer under the passage may need the water company's agreement before building over or near it.
- The kitchen is usually out of use while the side wall comes down and the frame goes in, so many households set up a temporary kitchen elsewhere in the house. The rest of the property normally stays in use throughout the steel stage.
- Many outrigger kitchens have a chimney breast on the side wall being removed or on the party wall. Its position affects where beams can bear, and if any part of the breast is taken out, what remains above has to be supported as the engineer specifies.
What happens, step by step
Free visit
A short visit to Boston to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
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.
Steel in, made good
On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Approvals in Boston
For Boston, 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.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Local questions answered
Do you cover Boston for side return extension steels?
Yes. We carry out side return extension steels in Boston and the PE21 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Can I stay at home while the work is done in Boston?
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.
Do I need planning permission for a side return extension?
It depends on the house and where it is. Some side return infills can be built under permitted development, but the rules for side extensions are restrictive, and conservation areas and listed buildings add further controls. Check with your local planning authority or architect before committing to a design.
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.
Why does a side return need columns?
Columns are used where two beams meet or where there is not enough solid wall to carry the end of a beam. The column takes the concentrated load down to a pad foundation in the ground. Sometimes it can be hidden in a wall nib or boxed in neatly.
How much do side return extension steels cost in Boston?
As a guide, budget £3,450–£8,350 including VAT for side return extension steelwork in Boston, based on published UK cost guides adjusted for prices in the East Midlands (-2%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
