How Much It Costs to Build a Double Garage in the UK

Typical Cost Ranges

Building a double garage in the UK can vary significantly in cost depending on the size, materials, finishes, and location. A basic double garage with a flat roof and standard materials might cost in the region of £30,000 to £47,000. If you choose a pitched roof with tiles, higher quality doors and windows, better insulation, and more detailed finishing, the price usually falls between £36,000 and £58,000 or more. These figures include labour and materials and are based on a mid level specification rather than the cheapest or most high end finishes available. Prefabricated or modular double garages can be less expensive, although they generally offer reduced durability and insulation compared with a fully built masonry structure.

What Influences the Cost

Several key factors influence the total cost of building a double garage. Size and footprint play a big role, as the larger the structure the more materials and labour are required. Roof style is another consideration, with flat roofs being quicker and cheaper to build, while pitched tiled roofs are more expensive but provide better aesthetics and drainage. The choice of materials, from bricks and blocks to roofing tiles and insulation, also makes a difference. Higher quality doors, windows, and finishes naturally increase costs.

Ground conditions and foundation requirements can also add to the price. If excavation, levelling, or drainage work is needed, the overall cost will rise. The choice of garage door, whether a basic manual up and over or a modern insulated electric sectional door, can have a big impact. Internal finishes such as plastering, electrics, heating, or flooring all add further expense. Labour costs vary across the country, with London and the South East generally being more expensive than other regions. Finally, regulatory requirements such as Building Regulations and design fees should also be budgeted for, as these can add both time and cost to the project.

Example Budgets

To give a sense of real world figures, a modest double garage with a flat roof, standard brickwork, a single large door, and minimal extras might cost between £30,000 and £38,000 in many areas. A mid specification build with a pitched tiled roof, some insulation, a good quality electric door, and windows is more likely to fall between £40,000 and £55,000. A high end garage with bespoke features, extensive glazing, high grade roofing materials, loft storage, and premium finishes can easily exceed £60,000, especially in expensive regions.

Things to Factor Into Your Budget

When planning your budget, it is important to think about more than just the walls and roof. A proper foundation and base slab are essential, and site preparation such as levelling or drainage work can add to costs. Building control fees, structural engineering if required, and planning considerations should all be factored in. You will also need to budget for doors, windows, roofing, guttering, fascias, and finishing to match your existing property if required. Internal details such as lighting, wiring, heating, insulation, and plastering can turn a basic garage into a more useful space but will push the budget upwards.

Conclusion

The cost of building a double garage in the UK will generally fall somewhere between £30,000 and £58,000, with basic structures at the lower end and larger or more complex designs at the top. The main drivers of cost are size, roof style, materials, and finishes, along with labour rates and any site-specific challenges. Careful planning and budgeting will help you stay in control of costs and ensure your garage is built to the standard you expect.
