Factors affecting the average cost of garage conversion

A few things affect how much it costs to convert a garage into a room. We'll discuss them below:

Target room type

The costs of converting your garage differ according to the type of room you want to transform it into. Costs can quickly escalate and reach $45,000 when converting a space to a kitchen or bathroom since these rooms need additional plumbing to get clean, flowing water in.

Garage to bedroom conversion costs could also go higher based on the design, style, and finishing, especially if you hire a floor planner or designer. Bear these in mind when finalizing your budget.

Garage size

Garages can be classified based on how many cars can fit inside. Single garages can fit one car, while double garages can fit multiple vehicles. Of course, single garages are often smaller and cheaper to convert.

Single garage conversion costs range from $5,700 to $25,000. On the other hand, double garage conversion costs around $20,000 to $30,000. Despite the higher price, converting a double garage can be incredibly useful if you need more space in your home.

Reasons to convert your garage

Now that you’re familiar with the factors that affect costs, here are some of the advantages of garage conversion: 

  • It creates a more liveable space in your home while reducing house extension costs.
  • It frees up space inside your home to avoid overcrowding while making more use of a ’junk room.’ 
  • It increases property value and helps add more practical areas to your home (e.g., entertainment room or mini office).

It’s wise to work with a residential architect before you find a builder or coordinate with them at the same time for a solid design plan.
