Turning a large house into flats or an HMO rarely leaves every wall where it was. Rooms are split and joined, kitchens and bathrooms appear on upper floors, and new stairs or corridors are formed. Each time a load-bearing wall moves, steel usually takes its place, and it has to suit the fire and sound standards of a building shared by several households.
Things to plan for
- In a conversion, walls that carried load are often taken out to form open kitchens or wider corridors, while new partitions go in elsewhere. Each change is checked, because a new stud wall standing on old joists can add load the floor was never designed for.
- The reduced 5% rate of VAT may apply to some conversion work, such as changing the number of dwellings in a building. Whether it applies depends on the details of the scheme, so confirm the position with your accountant before relying on it.
- Separating floors and walls also have to meet sound insulation standards. Steel connections and boxing are detailed so they do not leave gaps or rigid paths for noise, and sound testing near completion checks that the separating construction performs.
- Floors and walls between flats must resist the spread of fire, and steel holding up those floors needs protection to match. Where a beam passes through a separating wall or floor, the gaps around it are fire-stopped so the separation stays continuous.
- Keep the structural calculations, building control completion certificate and fire protection records together in one place. They are needed for signing off the conversion, and buyers, lenders and licensing officers may ask to see them later.
How the job runs in Cricklewood
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.

Approvals in Cricklewood
Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
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 you work on older or listed homes in Cricklewood?
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.
How much do flat & HMO conversion steels cost in Cricklewood?
As a guide, budget £3,200–£11,500 including VAT for steelwork for a flat or HMO conversion in Cricklewood, based on published UK cost guides adjusted for London prices (+28%). 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.
What steel beams are needed for a flat conversion?
It depends on how much the layout changes. Typical steelwork includes beams where load-bearing walls are removed, trimmers around new stair openings, and columns or frames where loads have to come down through the building. A structural engineer designs each element from the new layout and the existing structure, and the calculations go to building control.
How is sound insulation handled around steel beams in flats?
Through careful detailing. Separating floors and walls between flats must meet sound insulation standards, so steel connections, boxing and packing are designed not to leave gaps or create direct paths for noise. In England and Wales, sound testing is normally carried out on conversions before completion to show the separating construction performs.
How long does the steelwork take on a house-to-flats conversion?
Typically one to three weeks on site, depending on how many walls move and how the work is phased. The steel is usually among the first structural stages, so it is programmed early to let partitions, services and fire separation follow. The full conversion takes considerably longer than the steelwork alone.
Who approves flat & HMO conversion steels in Cricklewood?
Structural work in Cricklewood needs a building notice or full plans application to the local council's building control team or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
