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.
What to expect
- 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.
- Where the building is leasehold, or an existing flat is being altered, the freeholder's written consent is normally needed for structural changes. Lenders may also want to see building control sign-off before releasing funds on a converted property.
- A conversion to flats or an HMO may need planning permission for the change of use, depending on the scheme, its size and any local restrictions. Checking the planning position before design work begins avoids redesigning the layout and its steel later.
- Costs reflect how many walls move, the number of beams and columns, access for lifting steel to upper floors, the fire period required, phasing around other trades and whether existing foundations can take the new concentrated loads.
- Many HMOs need a licence from the local council, with conditions covering room sizes, shared facilities and fire safety. Licensing runs alongside building regulations rather than replacing them, so the layout and steelwork should suit both from the outset.
From survey to sign-off in New Milton
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 control and neighbours in New Milton
For New Milton, 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.
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 New Milton?
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.
Do I need a party wall agreement for flat & HMO conversion steels in New Milton?
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.
Do I need planning permission to convert a house into an HMO?
You may, depending on the size of the HMO, where it is and any local restrictions. In some areas smaller HMOs can be formed without a planning application, while larger ones, and conversions into self-contained flats, usually need permission. Check with the local planning authority before committing to a layout and its steelwork.
Do I need building regulations to convert a house into flats?
Yes. Converting a house into flats is a material change of use, so the building has to meet requirements for fire safety, sound insulation, structure and other matters. In England and Wales that means a building control application, in Scotland a building warrant before work starts, and in Northern Ireland an application to council 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.
