Before choosing rooflights or a dormer, we test whether the existing house can take a useful stair, the new structure and the fire-safety work. Those constraints determine how much of the apparent loft area can become a practical room.
Sweet Homes builds loft conversions in Edinburgh as contractor from the design, structural information and approvals supplied through the professionals you appoint.
Headroom in the middle of the roof can make a loft look generous. The stair arrives at an edge, passes through the floor below and needs a workable landing. Structure, escape, insulation and services reduce the area that can be used.
We use the initial conversation to establish the intended room, the property type and what professional information already exists. Your architect owns the design. Your structural engineer supplies the structural information. You appoint the building-warrant route and any planning or listed-building advice needed for the proposed roof changes.
Sweet Homes remains the construction contractor. Our written scope may include structural floor and roof work, openings and weathering, insulation, stairs, internal services, plastering, joinery and finishes. Electrical and gas work is carried out and certified through the competent trades we appoint.
An untested stair position or unfinished structural brief leaves design questions open. The quotation lists the missing information and identifies what still needs to be decided.
These ranges were already public. They are indicative 2026 homeowner totals including VAT at the current 20% standard rate; the underlying plus-VAT bands are retained in brackets, not fixed quotations.
| Typical scope | Homeowner total, including VAT (underlying band plus VAT) |
|---|---|
| Rooflight conversion where the existing roof has suitable geometry | £30,000–£45,600 including VAT (£25,000–£38,000 plus VAT) |
| Rear dormer adding useful headroom and floor area | £45,600–£69,600 including VAT (£38,000–£58,000 plus VAT) |
| Hip-to-gable with rear dormer, en-suite or larger upper-floor scope | £69,600–£108,000+ including VAT (£58,000–£90,000+ plus VAT) |
Stair design, structural work, roof condition, dormer weathering, fire-safety measures, plumbing and finish choices can move the price outside a band. The approved information and measured property are needed for the quotation.
The household may be able to stay while much of the roof work remains separated. The opening for the stair and any rewiring, extensive plumbing or heating changes can alter that quickly.
We discuss the affected rooms and essential services before site work. Sweet Homes may recommend a holiday over the disruptive stretch. Temporary arrangements and any daily service promise belong in the particular contract.
Ask about the loft and the stair
If the roof will not give the headroom or the stair will not land, the same floor area is sometimes cheaper to find elsewhere. Home extensions build outward from the existing structure, garage conversions reuse a structure that already has walls and a roof, and structural alterations rework the space inside the walls you have. Those are different projects with different approvals, not cheaper versions of this one.
How much does a loft conversion cost in Edinburgh?
The bands published above run from £30,000 including VAT (£25,000 plus VAT) for a rooflight conversion where the roof geometry already suits it, to £69,600 and beyond for a hip-to-gable with a rear dormer and larger upper-floor scope. Stair design, structural work, roof condition, dormer weathering, fire-safety measures, plumbing and finishes move a project within or outside a band.
Is my loft tall enough to convert?
Headroom in the middle of the roof can make a loft look more generous than it is. Structure, escape, insulation and services all reduce the area you can actually use, so the usable room is smaller than the floor you can see. That is measured against the property rather than estimated from a photograph.
Where does the staircase go?
That question comes before pricing the room, not after it. The stair arrives at an edge of the loft, passes through the floor below and needs a workable landing. An untested stair position leaves the design open, and the quotation lists what still needs to be decided.
Does a loft conversion need a building warrant?
A loft conversion normally does, and roof changes may raise planning or listed-building questions as well. You appoint the building-warrant route and any planning or listed-building advice the proposed roof changes need. Your architect owns the design and your structural engineer supplies the structural information; Sweet Homes builds from what they produce.
How soon can the work start?
We do not book works within four weeks of a first enquiry. That period covers the call, the survey, the written quotation, your decision and the ordering that has to happen before trades arrive. If something needs attention sooner than that, say so on the call and we will point you to the right emergency trade for the immediate problem while the planned work is scheduled properly.
What happens after we enquire?
We reply by email. If the project looks like a fit we ask for the property details, any drawings or approval information and a few photographs, then arrange a twenty-minute call to work through the brief. A site visit follows the call, and the written quotation follows the visit. Send a couple of windows that suit for the call and we will hold the time.
Tell us the property and how you would like to use the loft. Our team replies by email and arranges a short call to talk through head height, stair position and warrant requirements.
Our team reviews every enquiry. We use your details to reply and handle the service you request. Privacy notice.
