Flat & HMO conversion steels in Andover: how it works

If you live in Andover, flat & HMO conversion steels can usually be planned and priced after a single survey visit. We also cover the surrounding towns and villages in Hampshire. We cover SP10 and SP11, and we fix the price in writing once the layout and scope are agreed.

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

  • 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.
  • 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.
  • Converting a house into flats is treated as a material change of use for building regulations purposes, so fire safety, sound insulation and other requirements apply across the building, not just to the structural work. The steelwork forms one part of that wider approval.
  • 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.
  • 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.

What happens, step by step

  1. Free visit

    A short visit to Andover to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. 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.

  4. 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.

Building rules for Andover

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.

Local questions answered

Do you also work near Andover?

Yes. We also cover nearby towns including Winchester, Newbury, Salisbury and Thatcham.

Can I stay at home while the work is done in Andover?

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.

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.

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.

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.
