What steel columns & posts involve in Richmond
If you live in Richmond, steel columns & posts can usually be planned and priced after a single survey visit. We also cover the surrounding towns and villages in London. We cover SW14, TW1, TW2, TW3 and TW7, and we fix the price in writing once the layout and scope are agreed.
Sometimes the right support for a beam is not a wall at all. A long span can be broken in two with a slim post in the middle, a beam can land on a column where the masonry below is weak, or the corner of an L-shaped opening can be held up by a single post instead of a brick pier.
Key points for your project
- 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.
- Placing a post well can make an open-plan room work better. It can mark the edge of a kitchen island, frame a dining area or line up with a worktop end, so it reads as part of the design rather than an obstruction.
- 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.
- The base plate is welded to the foot of the column and fixed to the pad with holding-down bolts. A cap plate at the top bolts to the beam above, so the two act together and the beam cannot slide off its support.
- While the existing support is removed or the new column goes in, props hold the beam and the structure above. They are only taken out once the column is fixed, packed tight at the head and grouted at the base.
What happens, step by step
Free visit
A short visit to Richmond 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.

| Basement or cellar steelwork | £3,200–£8,300 | Beams and columns with pad foundations under the floor above (excavation and waterproofing extra) |
| Kitchen-diner knock-through | £3,200–£7,700 | Internal structural wall between kitchen and dining room, steel beam, approvals and making good (kitchen fitting extra) |
| Structural calculations for a beam | £320–£960 | Site measure or photos, beam and padstone design and calculations for building control |
Figures include our approximate regional adjustment for London prices (+28%) and are rounded. How these figures are worked out.
Approvals in Richmond
For Richmond, 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 also work near Richmond?
Yes. We also cover nearby towns including Isleworth, Hounslow, Barnes and Chiswick.
Do I need a party wall agreement for steel columns & posts in Richmond?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
What is the difference between a column and a padstone?
A padstone is a block bedded into a wall to spread a beam's load into the masonry beneath. A column replaces the need for a wall altogether, carrying the load down to its own foundation. Where the wall below a beam end is too weak for a padstone, the engineer may call for a column instead.
Can a steel post replace a supporting wall?
Yes, in many layouts a wall can come out with a beam above it and one or more posts taking the beam's load down to the ground. This keeps most of the openness while shortening the span. The engineer decides how many posts are needed and where they can go.
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.
How soon can steel columns & posts start in Richmond?
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.
