About our loft conversion steels service in Devon

Loft conversion steels are the beams that let a roof space become a usable room. They carry the new floor so it does not rest on the old ceiling joists, support the roof where purlins and struts are removed or rafters are cut for a dormer, and bear onto padstones in the gable or party walls as a structural engineer specifies.

From the first survey visit to the completion certificate, we take care of loft conversion steels across Devon. That includes Bideford, Torquay and Exeter, plus smaller towns and villages nearby. The engineer sizes the steel, we deal with building control, and our team fits and packs the beam before making good.

Things to plan for

  • In older terraces the party wall at loft level can be thin, built in soft brick, or contain old chimney flues. The engineer may avoid bearing over a flue, ask for a section of wall to be rebuilt, or use a post down to firmer support.
  • Many later twentieth-century homes have trussed rafter roofs, with diagonal timbers running through the whole loft. Converting these involves more steel and new timber, because each truss is cut and its load has to be re-routed by design.
  • Steels supporting a loft floor commonly need 30-minute fire resistance in a typical house. That is usually achieved with fire-rated plasterboard below and around the steel, to the specification agreed with building control.
  • Getting steel into a loft is often the hardest part of the job. Beams can be brought through a roof opening, a gable window, or in shorter lengths bolted together inside, provided the engineer's design allows for the splice.
  • Traditional cut roofs rely on purlins and struts running down to internal walls. A steel beam can take over that job so the struts come out, freeing up floor and headroom, but the change has to be designed and propped carefully.

From survey to sign-off in Devon

  1. Survey in Devon

    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.

  2. 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.

  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. 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.

Guide prices for loft conversion steels in Devon

Building rules for Devon

For Devon, 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 Devon?

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.

Can my loft be converted if it has trussed rafters?

Often it can, but it is a bigger structural job. Trussed rafters have diagonal webs right through the loft, and every truss that is cut needs its load picked up by new steel and timber. The engineer designs that, and the roof is propped carefully throughout.

How do you get steel beams into a loft?

It depends on access. Beams are often passed in through an opening made in the roof or a gable window, or brought up in shorter sections and bolted together in the loft where the engineer's design allows. For long or heavy steels a hoist or crane may be used, planned in advance.

How long does it take to install loft steels?

The main steels for a typical loft conversion usually go in over two to five working days. That covers cutting pockets, bedding padstones, getting the steel in and packing it. The timing depends heavily on access and how many beams the design calls for.

Do I need a party wall notice for a loft conversion?

Very often in England and Wales, because loft steels in terraced and semi-detached houses usually bear into the party wall. That is notifiable under the Party Wall etc. Act 1996, with notice served at least two months before the work starts. We organise this through a party wall surveyor as part of the job.
