A loft conversion turns unused roof space into a habitable room such as a bedroom, bathroom or office, with a proper staircase, insulation, fire protection and natural light from rooflights or a dormer.
We handle a loft conversion as a managed project across Aberdeen and Aberdeenshire: one contract, one contact, and trades working to an agreed specification. Coverage includes Aberdeen, Peterhead, Nigg and Inverurie and their surroundings. In Scotland the consent rules have their own details, which we check for you. Typical prices in Scotland fall within £29,000–£62,000, VAT included, and are fixed in writing after a survey.

How much does a loft conversion cost in Aberdeen and Aberdeenshire?
To help you plan, we show what a loft conversion typically costs in Aberdeen and Aberdeenshire instead of holding figures back for a sales call. The range is £29,000–£62,000 with VAT, using rates in Scotland that are about 4% below the national guide. A free survey then fixes your actual price.
| Type of job | What it usually involves | Guide in Aberdeen and Aberdeenshire |

| Dormer conversion | A rear dormer adding headroom and floor space, often with a bedroom and shower room. | £30,500–£58,000 |
| Hip-to-gable or mansard | Larger structural changes to the roof for the maximum usable space. | £48,000–£82,000 |

Homes in Aberdeen and Aberdeenshire
Aberdeen is built largely of grey granite, from tenements and terraces to granite villas in the West End, with post-war council housing and newer estates on the outskirts. Across Aberdeenshire, harled stone cottages, fishing-town terraces in Peterhead and Fraserburgh, and modern developments in commuter towns such as Westhill and Ellon are common.
Granite walls need repointing with a mortar matched to the stone, and slate roofs often want attention after hard winters. Harled cottages need breathable finishes, while newer estates commonly add extensions, garage conversions and driveways.
Cold North Sea winds, coastal haar and hard winter frosts are routine, so roofs, harling and exposed fixings need a robust specification.
Do you need permission in Aberdeen and Aberdeenshire?
Aberdeen and Aberdeenshire is in Scotland, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we quote.
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
It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about a loft conversion.
Price and scope agreed
We turn the survey notes into a written quote. The price is fixed for the specification we agree, and the document sets out materials, scope and payment stages in plain language.
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.
Finish and handover
Our trades complete a loft conversion while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.
How we work
Frequently asked questions
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.
Is my loft suitable for conversion?
A loft is usually suitable for conversion if there is enough head height, a roof structure that can be adapted and space for a staircase. A common rule of thumb is at least 2.2m from the top of the ceiling joists to the underside of the ridge, though dormers and mansards can create height where it is short. Modern trussed roofs need more structural work. We check all of this at the survey.
Do I need planning permission in Aberdeen and Aberdeenshire?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Aberdeen and Aberdeenshire is in Scotland, so Scotland's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
Can I put a bathroom in my loft?
A bathroom or shower room can usually be added in a loft conversion if waste pipes can reach the soil stack with enough fall, or a pumped system can be used. Dormers make this easier because they give standing height for a shower. Water pressure, extraction and the position of the boiler also matter. We plan the bathroom layout at the design stage so pipes are hidden in the structure.
