What Drives Cost Up (and Down)
Adds to Cost
- +Floor area — every extra m² adds cost
- +Design complexity: curves, cantilevers, raked ceilings
- +Difficult site: steep, poor soil, remote access
- +Premium selections: stone, European appliances, engineered timber
- +Passivhaus certification: triple glazing, HRV, continuous insulation
- +Pool, spa, or major external works
Keeps Cost Down
- —Compact, efficient floor plan
- —Simple rectangular form
- —Flat or gently sloping site
- —Standard selections from our preferred suppliers
- —Early brief lock-in — changes mid-build are expensive
- —Integrated design+build: no architect/builder gap
Cost Questions Answered
How much does it cost to build a custom home in Tasmania in 2026?+
Custom home builds in Tasmania range from $3,500 to $12,000+ per square metre depending on size, design complexity, site conditions, and sustainability features. A mid-range 240m² home typically costs $1M–$1.5M all-in including site works and landscaping.
What is included in the build cost?+
A Davies fixed-price contract includes all structural work, fit-out, fixtures, and finishes specified in the contract documents. It excludes: land purchase, council fees, soil tests, architectural fees (unless using Align Architecture), landscaping, and furnishings. We provide a full transparent cost breakdown before you commit.
How does Tasmania compare to mainland building costs?+
Tasmania typically runs 10–20% less than comparable builds in Melbourne or Sydney outer suburbs, and 30–50% less than premium mainland markets like Mornington Peninsula or Byron Bay. Combined with significantly lower land prices, your total investment buys considerably more.
What drives cost up in a custom build?+
The biggest cost drivers are: floor area (more m² = more cost), design complexity (curved walls, cantilevers, raked ceilings), site conditions (steep blocks, poor soil, remote access), premium selections (European appliances, stone benchtops, engineered timber floors), and sustainability specifications (triple glazing, HRV systems, solar).
Does Passivhaus cost more?+
A Passivhaus-certified home typically costs 10–15% more upfront than a standard build of equivalent quality. However, it reduces energy bills by 70–90% and dramatically improves thermal comfort and indoor air quality. On a 25-year view, it's almost always the better financial decision.
How accurate is the cost estimator?+
Our free Cost Estimator gives you an indicative range based on your inputs — useful for early planning but not a quote. An accurate cost requires a site assessment, your design brief, and a detailed quantity survey. We provide this as part of our Pre-Construction service.
