They are indicative 2026 homeowner totals including VAT at the current 20% standard rate; the underlying plus-VAT bands are retained in brackets. The construction scope may cover the floor build-up, moisture control, insulation, external openings, electrics, heating, plastering, joinery and decoration. Plumbing can be included where the approved proposal and drainage route allow it. Floor levels, moisture, structure, garage-door replacement, drainage, room use and finish specification move the price. The client-appointed team establishes the building-warrant, planning and listed-building routes that apply before the relevant construction starts. ## What a garage conversion includes A successful conversion starts with the parts that disappear behind the finish: the floor, moisture control, thermal envelope, structure and service routes. Three early checks shape the design: ### Floor and damp conditions Garage slabs can sit lower than the house and may need a different floor, insulation or moisture-control build-up. The quotation follows the measured condition and approved construction information. ### The front opening Replacing the garage door with an insulated wall and window usually makes the space perform more like the house. The external design and any planning constraint are checked before that option is fixed. ### Services and intended use A bedroom, office, utility or WC creates different heating, ventilation, fire-safety and drainage requirements. The room use is defined before the warrant drawings and quotation are settled. ## From feasibility to handover ## What happens around the build The first conversation looks at floor level, visible moisture, structure, access, services and the connection to the house. The written quotation records the construction scope, assumptions, exclusions and any condition that cannot be confirmed without opening-up. Once the necessary approved information is available, the construction can move through structure and moisture control, insulation and openings, first-fix services, boarding and plastering, then joinery, decoration and final fittings. If opening-up changes the known scope, the affected work pauses while the evidence and next construction options are recorded. The project contract identifies the completion test, snagging route and contractor or trade records Sweet Homes must provide. Approval completion remains with the client-appointed route.

Scottish building standards define that change as a conversion requiring a warrant. The approved design must address the standards relevant to the project, and work should not start before the warrant is granted. See the [Scottish Government conversion guidance](https://www.gov.scot/publications/making-quality-building-warrant-application-need-know/pages/6/). ### Do I need planning permission as well? **Do I need planning permission as well?** That is a separate check. The answer depends on the external alterations, permitted-development limits, planning history, conservation-area or listed status, and conditions affecting the property. We identify the proposed change and confirm the application responsibility before construction. ### How long does a garage conversion take? **How long does a garage conversion take?** A straightforward single garage is commonly four to six weeks on site. Plumbing, structural changes, a double garage or specialist finishes can extend the programme to six to ten weeks. Approval time sits before the relevant site work. ### Will it feel like a proper room? **Will it feel like a proper room?** It should be designed as one. Comfort depends on the surveyed floor and walls, moisture control, insulation, airtightness, heating and ventilation—not just the plaster and flooring visible at handover. ### Can the garage door remain? **Can the garage door remain?** Sometimes, but retaining vehicle access changes the thermal and airtightness strategy. Replacing the opening with an insulated wall and window is often the more practical route for an everyday room, subject to the property and approval checks. ### What happens if the slab or walls are worse than expected? **What happens if the slab or walls are worse than expected?** The project contract identifies how a changed condition, any required professional referral, variation approval and any effect on price or programme are handled for that scope. ## Related services and useful reading ### Home renovations Edinburgh ### [Home renovations Edinburgh](/home-renovations-edinburgh/) A wider multi-room or whole-home project coordinated under one scope.
