- Have an underutilised garage sitting on your Auckland property that could become a bedroom, studio, or minor dwelling?
- Want to add liveable space without the cost and consenting complexity of a brand-new build?
- Need a builder who understands the structural, drainage, and compliance challenges of converting an existing garage?
Your garage is already consented, already built, and already sitting on a concrete slab. Converting it into liveable space is often the fastest and most affordable way to add a bedroom, studio, home office, or self-contained minor dwelling on an Auckland site, especially when your section is too tight to build anything new. The question most homeowners start with is the right one: can council actually let me do this, and what will it cost?
Garage conversions are deceptively complex. District plan rules on site coverage, habitable room setbacks, ventilation, insulation, fire ratings, and emergency egress all come into play. If you’re converting to a self-contained dwelling, you may need resource consent on top of building consent. We flag every one of these issues in an upfront feasibility check so you know exactly what you’re dealing with before you commit a dollar to design.
Our motto is “spend the least amount possible in the right order to quantify the biggest uncertain costs,” and it especially applies to conversions where surprises hide inside existing structures. We check floor condition, moisture levels, structural capacity, drainage connections, and council rules before anything else. Want a quick indication of what your conversion might cost? Try our 60-second estimator.
If your conversion needs tie into additions, like building a new bathroom, extending the footprint slightly, or updating the exterior to match the main house, we handle that too. One team, one contract, one set of numbers from feasibility to code compliance certificate.

HOW WE WORK
Our Proven Process for Garage and Basement Conversions
Conversions are technically complex because you’re working within existing structures. Here’s how we de-risk the process:
Site Assessment and Feasibility
We inspect your existing garage, evaluate its structural condition, and check district plan rules for converting to habitable space. We assess floor levels, moisture, insulation potential, fire egress, and whether your conversion triggers building consent alone or resource consent too. You'll get a clear feasibility verdict and preliminary cost range with no commitment.
Design and Consent
We collaborate with your designer or recommend one experienced in garage conversions. Then we prepare and manage all council submissions, including building consent and resource consent where required, to ensure full compliance.
Pricing and Contract
An independent Quantity Surveyor reviews the full scope and provides a transparent, line-by-line cost breakdown. Once you're comfortable with the numbers, we proceed with a clear, fixed-price contract. No surprises.
Construction Management
Our team carries out the conversion: structural upgrades, insulation, lining, plumbing, electrical, and fitout. You'll get regular progress updates throughout, and we finish with a full walkthrough, code compliance certificate, and all documentation handed over.
Loft Conversions: Adding Living Space Above Your Existing Structure
A loft conversion turns dead space above your garage, workshop, or home into a fully liveable room without touching your footprint. On Auckland’s tight sites, where building outward isn’t an option, going up is often the smartest (and most cost-effective) way to add a bedroom, office, or self-contained studio. The question most homeowners start with is the right one: can my existing structure actually support it, and what will council need from me? We answer both before you spend a cent on design.
Every loft conversion is different because every existing structure is different. Roof pitch, floor-joist capacity, head height, fire egress, and district plan recession planes all dictate what’s feasible. We run a free desktop review of your site and structure so you know upfront whether a conversion is viable, what consenting path it falls under (building consent alone, or resource consent too), and what the realistic cost range looks like. No surprises three months in.
If it stacks up, we handle the full scope: structural engineering, architectural design, council applications, and the build itself. Most Auckland loft conversions we deliver sit between $150K and $350K depending on size and complexity, and we’ll give you a detailed estimate at feasibility stage so you can decide with real numbers, not guesswork.

Key Cost Drivers for a Conversion Project
- Size and Extent of Conversion: Converting a single garage into a basic bedroom or office will cost less than turning a double garage into a fully self-contained minor dwelling with kitchen and bathroom. The more square metres and the more services you're adding, the higher the cost.
- Existing Condition: The state of your garage matters. A damp slab may need a moisture barrier and new flooring. Old framing might need reinforcing. If the existing structure is in poor condition, additional work is needed to bring it up to liveable standard, which increases cost.
- Regulatory Compliance: Conversions must meet building code for habitable spaces: ceiling height, insulation, ventilation, fire safety, and emergency egress. If your conversion creates a self-contained dwelling, zoning rules and resource consent processes add to the scope. Compliance upgrades (fire-rated walls, upgraded wiring, new drainage connections) will add to the project cost.
- Access and Construction Logistics: If your garage is at the back of a tight property or access is limited, it may require more manual handling and smaller equipment, which can increase labour costs. If you're living on-site, we segment work areas and schedule carefully.
- Specialist Reports/Modifications: Some garage conversions need specialist input: a structural engineer to confirm load capacity for a mezzanine or upper level, a drainage specialist if you're adding a bathroom, or a geotechnical report if ground conditions are uncertain. These ensure safety and compliance but add to costs.
Frequently Asked Questions
Yes. Converting a garage to habitable space requires building consent at minimum. If you’re creating a self-contained dwelling (with its own kitchen and bathroom), you may also need resource consent depending on your district plan zone. We assess your specific situation in our feasibility check and handle the full application process for you.
In many cases, yes. Whether your garage can become a self-contained unit depends on site coverage rules, setbacks, parking requirements, and your zone’s rules on minor dwellings. We check all of this upfront and tell you plainly what’s possible before you spend on design.
Most garage conversions take 10–14 weeks to build once consent is granted, depending on complexity. Add 4–8 weeks for design and consenting beforehand. We’ll give you a realistic timeline at feasibility stage.
Yes. Since the work is in a separate structure, disruption to your main house is minimal. We manage site access and scheduling to keep your household running smoothly.
Most garage conversions we deliver range from $80K to $200K depending on the size of the garage, condition of the existing structure, and whether you’re adding plumbing for a kitchenette or bathroom. We provide a preliminary cost range at feasibility stage and a detailed, fixed-price quote once plans are finalised. No surprises.
