• Is over one storey high
• Covers more than 50% of your land

Are concrete garages any good?

Yes – modern concrete garages are durable, low-maintenance, and secure. They’re ideal for vehicle storage or workshops, lasting decades with minimal upkeep.

Benefits include:

• Excellent weather resistance
• Low maintenance compared to timber
• Quick installation (often in one to two days)
• Good value compared to brick builds
• Can be finished with uPVC, timber or composite cladding for a smart look
• Rendering and painting are also options for a modern finish

What is the cheapest type of garage to build?

A prefabricated concrete garage is typically the most affordable option. They’re factory-made and assembled on-site, saving on labour and materials.

Flat-roof designs cost less than pitched roofs, and opting for basic finishes (like unpainted concrete) keeps prices down further.

How long do concrete garages last?

A well-built concrete garage can last 30–50 years or more, especially if it’s installed on a solid foundation and maintained properly.
