Planning steel columns & posts in County Durham
A steel column is an upright structural element that collects the load from a beam, floor or roof and carries it down to a foundation. In homes it is usually a square or circular hollow section or a universal column, welded to a base plate fixed to a concrete pad, and sized by a structural engineer for the load it carries.
Across County Durham, steel columns & posts usually come up when people want more light, a better layout or a way through to a new extension. Towns we cover include Consett, Stanley and Hartlepool, among other places in the area. Whatever the reason, the beam is sized from calculations and the work is inspected before anything is covered.
Worth knowing before you start
- Adding a structural column is building work that building control needs to approve, with the pad usually inspected before concrete and the column before it is covered. The completion certificate at the end is the record to keep for any future sale.
- Older properties sometimes have cast iron columns, timber posts or brick piers doing this job, especially in cellars and former shops. Their condition and capacity are often unknown, so the engineer assesses whether they can stay or need replacing with new steel.
- A column delivers its load to the ground through a small area, so it normally stands on a concrete pad foundation rather than straight onto a floor slab. The pad spreads the load into firm ground at a depth set by the engineer.
- Steel at floor level can corrode if it sits in damp. The detail at the base is designed to keep damp away, using grout, protective paint and the floor's damp-proof membrane, and a column in a cellar or garage may need a heavier coating.
- The noisiest part is cutting the floor and digging the pad, usually a day's work. The concrete then needs time to gain strength, so the column is often fitted on a later visit once it has cured enough to take load.
Four stages, one team
Survey in County Durham
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
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.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Approvals in County Durham
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.
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
How soon can steel columns & posts start in County Durham?
Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
How much do steel columns & posts cost in County Durham?
As a guide, budget £460–£1,400 per column including VAT for steel column or post in County Durham, based on published UK cost guides adjusted for prices in the North East (-7%). 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.
Can I put a steel post in the middle of a beam?
Yes, a central post is a common way to support a long beam, and it often lets the engineer specify a shallower steel. The post needs its own foundation and has to sit somewhere that works with the room layout. The engineer compares a post against a single deeper beam and specifies whichever suits the loads and the space.
Can a steel column be left exposed?
Yes, many people leave a column on show, painted to suit the room. In homes exposed steel commonly needs fire protection, often intumescent paint applied to the specified thickness as part of a compatible paint system. Building control checks the protection meets what was specified. Boxing in with fire-rated plasterboard is the alternative where a hidden column is preferred.
Does a steel column need a foundation?
Almost always, yes. A column puts a concentrated load onto a small patch of ground, and most floor slabs are not designed for that. The engineer specifies a concrete pad of a set size and depth, building control usually inspects the hole before concrete is poured, and the column is bolted down once the pad has cured.
Can you replace an old timber or cast iron post?
Usually, yes. Old posts in cellars, garages and converted shops are often undersized, rotten or of unknown strength. The engineer assesses the load they carry and specifies a new steel column and pad. The structure is propped while the old post comes out, and the new column is packed tight before the props are removed.
Can I stay at home while the work is done in County Durham?
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.
