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: 

  1. It creates a more liveable space in your home while reducing house extension costs.
  2. It frees up space inside your home to avoid overcrowding while making more use of a ’junk room.’ 
  3. 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.

Garage conversion to a granny flat costs around $50,000 to $80,000 but can go higher or lower depending on the size of the space, location, and complexity of the project. Garage-to-studio conversion costs are similar to those of granny flats since these are both under garage-to-loft remodeling.

An architect knows how to make the most of your space, which can increase its monetary value if you plan to put the house up on the market. They can also help you navigate building permits and planning permissions if needed. 

A building permit is needed in conversion projects since you will be changing the usage of your home space. Securing a permit ensures that the new space complies with building regulations and that the safety of inhabitants and the surrounding area is preserved. 

The application starts with submitting plans to your city’s housing and urban development department. It’s best to consult your local authority regarding practices, codes, regulations, and fees to make sure you know the rules governing your area.
