What is a Garage Conversion?
A garage conversion is the process of converting a garage into a habitable room. Garage conversions can be used to create a variety of different spaces, such as bedrooms, bathrooms, home offices, or even granny flats.
Why Consider a Garage Conversion?
There are many reasons why you might consider a garage conversion. Some of the most common reasons include:
- Need more space: A garage conversion is a great way to add extra square footage to your home without the need for a major addition.
- Increase your home’s value: A garage conversion can add significant value to your home.
- Create a more functional space: If you’re not using your garage for its intended purpose, a conversion can help you create a more functional space for your needs.
Factors Affecting the Cost of a Garage Conversion
The cost of a garage conversion can vary depending on a number of factors, such as:
- The size of your garage: Larger garages will obviously cost more to convert than smaller garages.
- The type of conversion you’re planning: A simple conversion, such as a bedroom, will typically cost less than a more complex conversion, such as a bathroom or kitchen.
- The materials you choose: The materials you use for your conversion will also affect the cost. For example, using high-end finishes will cost more than using more basic materials.
- The complexity of the project: Some garage conversions will be more complex than others. For example, if your garage has a slab foundation, you will need to add a new foundation for your conversion. This will add to the cost of the project.

Checklist for garage conversion eligibility
Before you start planning your garage conversion, it’s important to check if your garage is eligible for conversion. Here’s a checklist to help you get started:
- The garage must be structurally sound. This means that the walls, roof, and foundation must be in good condition and able to support the weight of a habitable room.
- The garage must have a ceiling height of at least 2.4 meters. This is the minimum ceiling height required for habitable rooms in New Zealand.
- The garage must have adequate natural light and ventilation. This can be achieved by installing windows and/or an air ventilation system.
- The garage must be weatherproof. This means that the roof, walls, and doors must be in good condition and able to keep out the elements.
- You may need to obtain building consent from your local council. This will depend on the complexity of the conversion.
It’s important to consult with a qualified builder or building surveyor to determine if your garage is eligible for conversion and to get advice on the best way to proceed.
