Planning wider doorways & openings in Perth

Planning wider doorways & openings in Perth? Our team covers PH1 and PH2 and the streets around them. The wider Perth and Kinross area is covered as well. You get one written quote for the calculations, approvals, propping, steel and making good.

We arrange a survey visit, structural calculations where the wall is load-bearing, building standards, propping, the lintel or beam, new door linings if you want them, and making good. One itemised written quote covers the lot, and the price is fixed in writing once the opening size and finish are agreed.

What to expect

  • Older door surrounds and walls can hide asbestos in textured coatings, insulating board above doors or panelling. In buildings built before 2000 it must be identified before the wall is cut, so a refurbishment survey of the area is arranged where there is a risk.
  • In older houses, a doorway may already have a timber lintel that has rotted or a brick arch that is hard to extend. These are replaced rather than added to, and the engineer allows for soft lime mortar and any cracking found once the wall is opened.
  • In hallways, a new or wider opening into the living room can affect the protected route from the stairs to the front door. Building standards may require fire doors, smoke alarms or other measures, especially in houses with three or more storeys.
  • When an opening widens, the old threshold strip and floor finishes often stop short. Carpet, boards or tiles need joining neatly across the new width, and a change in floor height between rooms may need a threshold bar or a gentle ramp.
  • For a modest increase in width, a lintel may be all that is needed, while a wider opening carrying a floor or wall usually needs steel. The engineer chooses the type and size from the actual loads, never from the opening width alone.

From survey to sign-off in Perth

  1. 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.

  2. Design and price

    Calculations come back from the engineer and we confirm your fixed written price, line by line.

  3. Building warrant

    A building warrant is applied for from Perth and Kinross Council, and work starts only once the warrant has been granted.

  4. Fit, inspect, finish

    The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

How much should I budget in Perth?

JobTypical guide rangeWhat it usually covers
Widening an internal doorway£910–£2,280Opening widened with a new lintel or short beam, approval where structural, and making good
Load-bearing wall removal with steel beam£1,800–£4,550Typical internal wall up to about 4 m: calculations, building standards, propping, steel, padstones, fitting, fire protection and making good
Building warrant fee£215–£435Statutory fee set by the estimated value of the work: £215 up to £5,000, rising on a sliding scale (fees from 1 April 2026)
RSJ supply and fit (single beam)£730–£2,280 per beamBeam supplied, delivered, lifted and packed on padstones, with propping (calculations and approval priced separately)

Figures include our approximate regional adjustment for prices in Scotland (-9%) and are rounded. How these figures are worked out.

Approvals in Perth

Scottish rules are stricter on timing than in England: the building warrant must be in place before the wall is touched. We prepare the application with the engineer's calculations and submit it to Perth and Kinross Council. The finished work is then certified and a completion certificate submitted for acceptance.

Scotland has no Party Wall Act. Work affecting a shared wall is governed by your title deeds and the general law, and in flats by the Tenements (Scotland) Act 2004, so it is sensible to agree the work with neighbours in writing before starting.

Local questions answered

Do I need a party wall agreement for wider doorways & openings in Perth?

There is no Party Wall Act in Scotland. Your title deeds and the general law apply instead, and the Tenements (Scotland) Act 2004 for flats, so agree the work with your neighbour in writing before it starts.

What happens at the survey visit in Perth?

We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.

Is a lintel or a steel beam needed for a wider door?

It depends on the loads. A lintel can be enough for a modest widening under light loads, while an opening carrying floor joists or a wall above usually needs steel. The engineer decides from the actual loads and span rather than the width alone, and we fit whichever is specified.

How wide can I make a doorway?

That depends on the wall, what it carries and how much solid wall is left at each side for the support to bear on, and a structural engineer sets the limit. Many people go from a single door to a double-width opening, and beyond that the job starts to become a partial wall removal.

How long does it take to widen a doorway?

The structural part usually takes one to two working days: propping, cutting the opening, fitting the lintel or beam and packing it. Plastering follows, then a few days of drying before linings are painted or a new door is hung. Building standards inspection fits in once the support is in place.

Can you work on older or listed homes in Perth?

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.
