Good buildings come from good people, and all problems are solved by good design.


Garage conversions remain a popular choice among homeowners. They are one of the most effective ways to increase the livable space and value of your home.

While trading in your garage for living space means foregoing a covered parking space, in cases where extra rooms are required, this sacrifice is often completely worth it.

When a garage is constructed, it does not have to meet the same requirements as a home under the Building Code and are therefore not suitable for habitable purposes i.e. non-habitable.

The conversion of a non-habitable space to a habitable space is considered an ‘alteration to an existing building’ rather than a ‘change of use’. The council requires that converted non-habitable spaces comply with the Building Code wherever possible to ensure that the homeowners live in a safe and healthy building.

Garage Conversions


Garage Conversions are a good option if you want to add more living space to your home without extending the footprint of the house. However, there are a few council requirements for the conversion, for example;

  • Council requirements – conversion of non-habitable space to habitable space.
  • Insulation, building wraps and internal linings are installed. This may require the removal removing of the external cladding so that insulation and building wrap can be installed.
  • Damp proof membranes are in place. This relates to the concrete slab. Typically membranes are placed between the ground and concrete to prevent moisture migrating into the building. Where a membrane has not been placed a topping or surface coating maybe required to protect the internal environment.
  • Providing adequate light and ventilation.
  • If a bathroom is to be built there must be adequate provision for the disposal of internal moisture i.e. steam from showers.
  • Floor, wall and ceiling surfaces are to be sealed, painted or covered.
  • Converting a non-habitable to habitable space usually needs a building consent under the Building Act.


If you have a suitable property that lends itself to a garage conversion, a set of existing floor plans, or just want to be involved in each step of your renovation design, then you should consider using the services of a renovation company such as Style Plus Renovations.

After you have gathered your thoughts on what the new space will be used for, you will need to engage an experienced architect to create the plans for your renovation.
