Rising material costs, labour rates, and regional differences around the UK continue to affect the cost to build a garage UK. Understanding the expenses involved will help you to prevent cost overruns, whether your intended small single garage or a large double garage.
Four common garage designs will be thoroughly compared in this guide: single garage with a flat roof, single garage with a pitched roof, double garage with a flat roof, and double garage with a pitched roof. Along with building costs per square metre, this guide also features regional rate comparisons throughout the UK.
Calculating Building A Garage Costs
Our calculations followed a consistent approach over several areas. The cost comparisons presume the garage is an addition to an existing house, not a brand-new detached construction. These exclude appliance and electric vehicle charger installation.
Usually, garages in the UK have sizes
- Single: 10 x 18 feet (3 m x 5.5 m, with a 16.5 m² gross external area).
- Double: 18 x 18 feet (5.5m x 6m, with a gross external area of 33m2)
We have calculated the expenses in this article using both of these measurements.
