Indicative construction cost only, and it excludes design fees, consultants, council contributions and landscaping — see what else sits in a budget. The base rate is our 2026 starting point for architectural work; the real number comes from a drawn design on a surveyed site.
The way to a real number
Sketch design. Fixed fee. Two options, one feasibility.
A calculator gives you a direction. A drawing gives you a number. Our sketch design stage is a fixed-fee piece of work: we read the site, build the brief around what you need versus what you want, and draw two opposed options — each with its own cost range.
It closes with a pre-build feasibility: total project investment, not just the build. Design fees, consultants, authority contributions, site works and construction, in one document.
The builder is in the room from the first sketch. That is the whole point of how this practice is put together — the person who will price it is the person watching it get drawn.
Fixed fee. Defined deliverable. No obligation to continue past it.
What moves the number
Four things decide the price, and floor area is the weakest of them.
Detail, not floor area
Two homes of identical size can differ by a factor of two. Concealed fixings, shadow lines, flush thresholds, minimal reveals — dark architecture removes the trims and beads that hide tolerance, and the labour to build without them is where the money goes.
The Tasmanian site
Slope, dolerite, access, bushfire attack level, coastal exposure and how far the services have to travel are all priced before a single frame goes up. Tasmanian blocks swing hard — a tight Hobart hillside and a flat Launceston lot are different projects before you draw anything.
Glass, structure and span
The moments that make a dark home — a corner that disappears, a roof that cantilevers, a wall of glazing facing weather — are structural decisions. They are worth paying for deliberately. They are ruinous when discovered late.
Performance in a cold climate
Tasmania has the heating load to make performance pay in a way it does not on the mainland. Building to a high-performance or certified Passive House standard typically adds around 15% up front and returns it in running cost, comfort and durability — decided at sketch stage, because it changes the wall build-up, not just the equipment.
Beyond the build figure
The costs people find out about last.
Almost everyone is given a construction number and discovers the rest in stages. Our pre-build feasibility puts all of it on one page at the end of sketch design, which is early enough to still change your mind.
- Design and documentation
- Architecture and interiors, typically referenced at 5–10% of construction cost depending on complexity.
- Consultants and reports
- Structural and civil engineering, soil classification, energy assessment, bushfire, surveying, wastewater.
- Council and authority
- Planning and building application fees, headworks and infrastructure contributions, any required bonds.
- Site works and services
- Excavation, rock, retaining, driveway, power, water, sewer or on-site wastewater, telecommunications.
- Landscape and external
- Terraces, decks, fencing, planting — the work that decides whether the building sits in the site or on it.
- Contingency
- A genuine allowance, held by you, not quietly absorbed into the build figure.
Where these numbers come from
A builder's data, not an architect's estimate.
Most design practices cost a project by rule of thumb, because they have no back-costed history to work from. Ours does. Kyle Zanetto's construction company, Zanetto Builders, has back-costed more than $20 million of completed Tasmanian homes and prices every project open-book — and that estimating discipline is what sits behind every figure on this page.
It is the same company that will build your house. That is the arrangement: the team costing your design at sketch stage is the team on site two years later, which is why our feasibility narrows rather than drifts. The estimate is tightened at the Silhouette when the design is modelled, and closed at the Blackprint when the documentation is complete enough to contract against.
Region by region, the construction team publishes its own detail: building costs in Hobart and the South, Launceston and the North, and the East Coast.

Frequently asked
Build costs, answered without hedging.
How much does it cost to build an architectural home in Tasmania in 2026?+
As a starting point, a considered architectural home in Tasmania begins at around $5,000 per square metre in 2026, and a dark, highly resolved home typically sits nearer $5,600–$6,200 per square metre before site and regional adjustment. Most of the projects we work on land between $850,000 and $4 million all up. A rate alone is a starting point, not an answer — the only reliable figure comes from pricing an actual design on an actual site.
Does it cost more to build a black or dark house?+
The colour costs nothing. The detailing does. Dark architecture is usually specified with concealed fixings, minimal reveals, flush junctions and continuous surfaces, because black shows every deviation. That level of resolution asks more of the documentation and more of the trades, and it is the reason we price the design while it can still change rather than after it is drawn.
Does it cost more to build in one part of Tasmania than another?+
Yes, and the gap is wider than most people expect. Hobart’s hillside blocks carry rock, retaining and access costs a flat Launceston lot does not. The East Coast and the far North-West add travel, accommodation and trade availability. Island and peninsula sites add freight and weather contingency on top of that. The regional adjustment on this page is indicative; the real figure comes out of a site visit.
Why is building in Tasmania more expensive than the mainland averages suggest?+
Freight across Bass Strait, a smaller trade pool bidding on a growing pipeline, and a cold-climate performance standard that a Queensland build simply does not have to meet. Set against that, land is generally cheaper and the quality of what you can build on it is exceptional. It is a different equation, not a worse one.
What is a realistic cost per square metre for a custom home in Tasmania?+
Custom builders across Australia commonly range from about $2,500 to $5,500-plus per square metre, and architectural, high-performance work in Tasmania sits at the top of that band and above it. Treat any rate as a direction, not a quote — floor area ignores site works, structure, glazing and finish level, which are precisely the things that decide the total.
What sits in a project budget besides the build cost?+
Design fees, consultants and reports, council and authority contributions, site works, service connections, landscaping and a genuine contingency. On a steep, coastal or remote Tasmanian site these can be a substantial share of the total, and they are the items most often discovered late. Our sketch design stage closes with a pre-build feasibility covering all of them, not just construction.
How much more does a certified Passive House cost in Tasmania?+
Around 15% more up front is a fair planning figure. Tasmania is where that investment repays fastest in Australia, because the heating load is real — energy demand for heating and cooling can fall by up to 80–90% against a standard home, alongside better comfort, air quality and building durability. Kyle’s construction team holds certified Passive House tradesperson credentials and has delivered a certified Passive House here.
Who actually builds the house?+
Zanetto Builders — Kyle’s construction company, whose builds have won six state awards across this portfolio. That is the point of the arrangement: the team costing your design at sketch stage is the team that will build it, using back-costed data from their own completed Tasmanian homes rather than a rate card.
When do I get a number I can actually rely on?+
At the end of sketch design, in the pre-build feasibility. That document sets out total project investment, not just construction, against a design you have chosen. The fixed-price contract number comes later, at the Blackprint, once documentation is complete enough to price without guessing.
Why won’t you publish a simple table of prices per square metre?+
Because a tidy table promises a precision it cannot deliver, and it is the fastest way to set an expectation that a real Tasmanian site will break. We would rather give you a range with the levers visible, tell you which levers move it most, and then price your actual design.
The next step
Get the real number.
A range is useful. A drawn, priced option is decisive. Sketch design is a fixed fee, ends in a pre-build feasibility covering your whole project, and carries no obligation to continue.
