Building in Bathgate
Edinburgh's New Town is a planned Georgian sandstone townscape within a World Heritage Site, and districts such as Marchmont and Leith have Victorian tenements. Bungalows and villas fill the suburbs, Midlothian has former mining villages, Livingston was built as a new town, and East Lothian villages often have red pantile roofs.
Listed and conservation-area homes need careful window and stone repairs. Bungalows commonly suit loft conversions and dormers, and suburban semis take extensions and garage conversions.
That mix of housing shapes how we approach a loft conversion in Bathgate: the age and construction of your home affect the materials, the method and, in the end, the price.
Do you need permission in Bathgate?
Each UK nation sets its own consent rules, and Bathgate is in Scotland. What follows is a plain summary; we check the specifics for your property with the council before pricing anything.
In Scotland, dormers are only permitted development in limited cases (for example, at least 10 m from the boundary the dormer faces, and not in conservation areas), so many loft conversions with dormers need planning permission. Rooflight-only conversions are often simpler.
A building warrant is required for a loft conversion in Scotland, covering structure, stairs, insulation and fire safety. There is no Party Wall Act.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
From survey to handover
Survey and measure
Book a visit and we'll come to you. The survey covers measurements, the state of what's there now and any obvious constraints, so the price that follows is based on your actual home, not an average.
Written quote
After the survey we send a quote for a loft conversion that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Plan and prepare
We handle the paperwork side: checking whether planning permission or building control approval is needed, submitting applications where they are, and scheduling the trades and materials around your dates.
On site to finish
The job proceeds in the order set out in the programme, with dust and debris kept under control. Finally we tidy away, inspect the work together and pass the finished project over to you with its paperwork.

Loft conversions in Bathgate: questions
Where will the new staircase go?
The new staircase usually sits above the existing stairs, rising from the landing so it uses space that is already circulation. Sometimes it needs to come from a small bedroom or box room, which reduces that room's size. Building regulations set rules on headroom, step size and handrails, with some flexibility for lofts. We look at options at the survey and show you how each affects the floor below.
What fire safety measures does a loft conversion need?
A loft conversion needs a safe way out in a fire, because the new room is high above the ground. This usually means a protected stair route down to an exit, with fire doors onto the stairway, mains-linked smoke alarms on each floor and sometimes an escape window. The exact approach depends on your house layout. Building control checks these measures before signing off the work.
Do you cover Livingston, Broxburn and Grangemouth?
Yes. As well as Bathgate, we cover Livingston, Broxburn and Grangemouth and the rest of Edinburgh and the Lothians. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
How much does a loft conversion cost?
A typical dormer loft conversion on a 3-bed semi costs £29,000–£62,000. A simple rooflight conversion costs less, while hip-to-gable and mansard conversions cost more because they change the roof structure. As a rough guide, allow around £800–£1,700 per square metre of new floor plus fixed costs for the staircase, steels and fees. Adding a shower room is the most common extra. We confirm a fixed price after surveying your loft.
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from a loft conversion, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
