Steel Garages & Metal Garages for Sale in the UK

Steel garages from Murray Steel Buildings start at around £8,700 for a single garage, with the final price depending on size, door and window specification, insulation, and any bespoke features you need. A typical double garage starts at a higher price point reflecting the larger footprint and additional steel. Because every garage we supply is designed bespoke to your requirements and engineered for the intended location, we provide a free no-obligation written quote within 24 hours of your enquiry — just contact us with your required size and use.

From order to completion, most steel garages are installed within 6-7 weeks, depending on design complexity and our current order schedule. After you approve the quote and design, we typically process the order and manufacture within 5-6 weeks, followed by delivery and on-site erection — usually 1–2 days for a single garage. We confirm an exact installation date once your foundation is ready, and our team handles the full build on-site UK-wide.

In most cases, a single steel garage built within your property’s existing curtilage falls under Permitted Development Rights and does not require planning permission — provided it stays within the size and height limits set by your local authority. Larger garages, those visible from a road, or buildings on Listed property or in Conservation Areas often do need permission. We can provide CAD drawings, structural calculations and design certificates required for any planning and building warrant application.

We supply steel garages in a full range of sizes, from compact single garages to large double or triple-bay garages, with bespoke dimensions to match your site and use. Common single garage sizes are around 3m × 6m, with double garages typically 6m × 6m or 6m × 9m and larger. Because every garage is designed individually, we can adjust width, length, eaves height, door positions, and roof pitch to suit anything from a domestic single-car garage to a multi-vehicle commercial workshop.

Yes — every Murray Steel Buildings garage is a prefabricated steel building, manufactured at our facility from galvanised cold-rolled steel sections and supplied as a complete kit. Prefabrication means faster, more predictable on-site assembly: our installation team erects the frame, roof, walls, doors, and any specified extras in a matter of days. Despite being prefabricated, each garage is custom-designed to your dimensions and requirements — so you get the speed and cost efficiency of prefab construction with the flexibility of a bespoke building.

Yes. Murray Steel Buildings is based in Dunfermline, Scotland, and we supply and install steel garages across the entire United Kingdom and beyond — from the Highlands to the South Coast. We never add additional charges based on your location: pricing remains the same whether you’re in Aberdeen, Cardiff, or Cornwall. Our installation teams are based throughout the UK to handle the on-site erection, and we coordinate delivery directly to your address.

Most steel garages sit on a reinforced concrete slab — typically 100–150mm thick for a single garage, with deeper foundations needed for double or larger structures. The exact specification depends on building size, soil conditions, and any local building regulations. When you order from Murray Steel Buildings, we supply the foundation specifications and structural calculations you’ll need for your groundworks contractor, so the base can be prepared before our team arrives to erect the building.

Yes — steel garages are well-suited to workshop conversion thanks to their wide-span, column-free interiors and ability to take a range of insulation systems. We can supply your garage with insulated wall and roof panels (PIR boards or composite sandwich panels), insulated personnel, roller shutter doors, insulated sectional doors, and provision for electrical and lighting installation. Many of our customers use insulated steel garages as home workshops, gyms, or storage spaces with year-round temperature stability. Just specify your intended use when you request a quote.
