Garage to bedroom conversion
Converting a garage into a bedroom or sleeping accommodation typically requires building consent and must meet building code requirements for habitable use. We assess your garage and handle all compliance, building, and project management so the space is legal and suitable for sleeping.
What a compliant bedroom conversion actually means
Converting a garage into a bedroom is classified as habitable use, which means the space must meet building code requirements for structure, insulation, fire safety, moisture, ventilation, and access. We assess your garage and advise on what's typically required so the conversion is compliant and suitable for sleeping.
Who this is for
Homeowners in Canterbury and Christchurch who want to create a compliant bedroom or guest room from their garage, and who prefer clarity over speed. We typically work with people who care about council compliance, resale value, and rental readiness.
Who this is not for
If you're looking for the cheapest or fastest option, or want to avoid consent requirements, we may not be the right fit. Bedroom conversions require full building consent and must meet habitable standards. We design for compliant, sleep-ready spaces, not shortcuts.
Consent and compliance for bedroom conversions
Converting a garage to a bedroom typically requires:
- Building consent, the space must meet building code requirements for habitable use
- Fire safety, appropriate fire separation and means of escape
- Insulation, walls, ceiling, and floor to meet code requirements
- Moisture and ventilation, appropriate cladding, underfloor ventilation, roof space ventilation
- Access and egress, safe entry and exit
We assess your situation and handle all compliance and building work. See our guides: garage conversion consent, building code, and insulation and fire safety.
Typical requirements for bedroom use
Bedroom conversions typically need:
- Habitable standards, proper insulation, ventilation, moisture management
- Fire safety, fire-rated construction where required, means of escape
- Separate access (if separate dwelling), independent entry where applicable
- Services, appropriate electrical, heating, lighting
- Privacy, separation from main dwelling where required
We design and specify what's typically needed for your situation. Every property is different; we assess on-site.

Timeline expectations
A typical garage to bedroom conversion may take:
- Assessment and design: 2–4 weeks
- Building consent: 4–8 weeks

These are ranges, not guarantees. Every property is different; we assess on-site and provide realistic timelines based on your situation.
Our process
We start with a feasibility assessment to clarify consent risk, key cost drivers, and whether conversion is the right option for your property. If it makes sense, we handle all compliance, do all building ourselves, and manage the job from start to finish. For details, see our our process page.
