About our loft conversion steels service in Plymstock

We carry out loft conversion steels in Plymstock, covering the PL1, PL3, PL4, PL7 and PL9 postcode districts. We also work in nearby Plymouth, roughly 2.4 miles away. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.

We fit the steel package for loft conversions, either as part of the full project or alongside your loft builder. That means the engineer's design, building control, getting long steels into a roof space safely, bedding them on padstones and packing them before the new floor and dormer go on.

Things to plan for

  • The steel stage of a loft conversion usually takes a few working days and comes early, before floor joists, dormer framing and insulation. Keep the steel calculations with the completion certificate, as both are asked for when the house is sold.
  • 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.
  • Ceiling joists in most houses are too shallow to carry people, furniture and a bathroom. Rather than loading them, steel beams span between the walls and new, deeper floor joists hang from them, sitting just above the old ceiling.
  • 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.
  • Many loft conversions in houses in England fall within permitted development. Roof extensions facing a road, work in conservation areas, listed buildings and flats generally need planning permission or another form of consent.

From survey to sign-off in Plymstock

  1. Free visit

    A short visit to Plymstock 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 Plymouth City Council, 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 control and neighbours in Plymstock

For Plymstock, building control is provided by Plymouth City Council, 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.

Questions about loft conversion steels in Plymstock

How soon can loft conversion steels start in Plymstock?

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.

Do you cover Plymstock for loft conversion steels?

Yes. We carry out loft conversion steels in Plymstock and the PL1, PL3, PL4, PL7 and PL9 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

Do I need building regulations for loft conversion steels?

Yes. Loft conversions are building work, and the steels form part of the structural design checked by building control in England, Wales and Northern Ireland. In Scotland a building warrant must be granted before work begins. The inspector checks the steel bearings before they are covered up.

Where do loft conversion steels sit?

Usually between the gable walls or party walls, bearing on padstones bedded into pockets cut in the brickwork. Floor beams sit low, close to the existing ceiling, while ridge or dormer beams sit higher up to support the roof. The engineer sets the exact positions and levels.

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.
