Flat & HMO conversion steels in Bonnyrigg: how it works
Bonnyrigg has a mix of housing, and flat & HMO conversion steels need a slightly different approach in each. The wider Midlothian area is covered as well. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.
We supply and install steelwork for landlords, developers and their builders, working from the engineer's design and fitting in with the wider conversion. We arrange structural calculations, handle building standards for the structural work or feed into your existing application, and fire protect the steel to the period the scheme requires.
Things to plan for
- 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.
- Keep the structural calculations, building standards completion certificate and fire protection records together in one place. They are needed for signing off the conversion, and buyers, lenders and licensing officers may ask to see them later.
- Large Victorian and Edwardian houses are popular for conversion, but they bring timber lintels, chimney breasts, lime mortar and joists notched for old services. These are uncovered early so the engineer can account for them before any steel is ordered.
- Conversions add kitchens and bathrooms upstairs, so soil pipes, water supplies and extract ducts need routes through the structure. Steel and joist positions are coordinated with these runs, and steel should never be drilled or notched on site without the engineer's approval.
- 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.
Four stages, one team
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 warrant
A building warrant is applied for from Midlothian Council, and work starts only once the warrant has been granted.
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 Bonnyrigg
Steel beam work in Bonnyrigg needs a building warrant from Midlothian Council. The structural design is part of the application, and the council's building standards team accepts the completion certificate once the work is done as approved.
There is no party wall notice system in Scotland. Instead, check your title deeds and, for flats, the tenement management scheme, and talk to neighbours early if the beam bears into a shared wall.

Questions about flat & HMO conversion steels in Bonnyrigg
Do you also work near Bonnyrigg?
Yes. We also cover nearby towns including Musselburgh, Penicuik, Tranent and Haddington.
What happens at the survey visit in Bonnyrigg?
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.
Can you install the steel while my main contractor runs the conversion?
Yes. On many conversions the steelwork is installed as a package within a wider build, working to the main contractor's programme and the engineer's design. We coordinate propping, deliveries and building standards inspections for the steel so the other trades can follow on smoothly once it is in.
Do I need freeholder consent to put a steel beam in my flat?
Usually, yes. If you own a leasehold flat, structural alterations normally need the freeholder's or landlord's written consent under the lease. In Scotland, the title deeds and the Tenements (Scotland) Act 2004 govern work affecting shared parts of the building. We can provide the calculations and drawings needed to support a consent request.
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.
