Planning basement & cellar steels in Corby
Corby has a mix of housing, and basement & cellar steels need a slightly different approach in each. Our coverage runs across Northamptonshire, so nearby villages are included too. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.
Underpinning and waterproofing are specialist trades, and we coordinate the steelwork with them rather than replacing them. Our part is the engineer's steel design, building control, temporary propping, and fitting the beams, columns and base plates at the right point in the dig, so the structure is sound before finishes go in.
Worth knowing before you start
- Converting a cellar into a habitable room is building work needing building regulations approval, covering structure, fire escape, ventilation and damp protection. Digging out a new basement may also need planning permission, depending on the council and the scale of the work.
- Temporary works for basements are more involved than for a single opening. The design covers propping the house above, supporting the sides of the excavation, and keeping loads off freshly cast concrete until it has gained strength.
- In terraced and semi-detached homes, basement work nearly always affects shared walls. Excavating near a neighbour's foundations and underpinning a party wall are both notifiable under the Party Wall etc. Act 1996 in England and Wales.
- Keep the engineer's calculations, waterproofing details, any party wall documents and the completion certificate together. Basement conversions attract questions from buyers' surveyors and lenders, and a complete paper trail makes those questions easier to answer.
- Getting steel into a basement means lowering it through a lightwell, a stair opening or a temporary hole in the ground floor. Long beams may be designed in bolted sections so they can be handled in tight below-ground spaces.
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 rules for Corby
In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.
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.

Basement & cellar steels in Corby: your questions
Do you cover Corby for basement & cellar steels?
Yes. We carry out basement & cellar steels in Corby and the NN17 and NN18 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Do you also work near Corby?
Yes. We also cover nearby towns including Uppingham, Kettering, Market Harborough and Oakham.
Do I need planning permission to convert a cellar?
Converting an existing cellar into living space usually does not need planning permission if the outside of the house is unchanged, though listed buildings need consent. Digging a new basement, extending under the garden or adding lightwells may need planning permission, and building regulations approval is needed either way.
Do I need a party wall notice for basement work?
In England and Wales usually yes, if you are excavating near a neighbour's foundations within the distances the Party Wall etc. Act 1996 sets, or underpinning a shared wall. Notice periods apply before that work starts. We arrange a party wall surveyor to handle the notices, though we do not give legal advice.
Do you do the underpinning for a basement?
Underpinning is specialist work, and we coordinate the steelwork with the underpinning contractor rather than carrying it out ourselves. The engineer designs the steel and the underpinning sequence together, so beams, columns and new foundations fit the order in which the walls are deepened.
What happens at the survey visit in Corby?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
