How Long Does It Take to Design and Build a House in Tasmania?
"When can you start?"
It's usually one of the first questions I'm asked. And I get it. Once you've decided to build, you want to get going.
But most people are surprised by how much happens before a builder sets foot on site.
THE SHORT ANSWER
Allow around 18 months to 2 years, from first enquiry to moving in.
Here's a look at what's involved in designing and building a home in Tasmania, whether it's a new build or a major renovation, and why it takes the time it does.
At a glance
Getting started: a few weeks to a month
Waitlist + site information: 3 to 6 months
Concept design
Planning approval: if required
Documentation + permits: often a year or more all up
The build: your builder's program
STAGE 1
Getting started
We meet to understand your site, brief and budget. I write a fee proposal so you know what's included and what it costs.
Time so far: usually a few weeks to a month.
STAGE 2
Waitlist + site information
Most building designers can't start your project tomorrow. Expect to wait at least three months, often longer.
We can often order some of the earlier consultant reports while you wait.
Time so far: 3 to 6 months.
There's a lot that goes on behind the scenes
Here are some of the most common consultants that may need to be involved before your home can be approved.
Land Surveyor: 4 to 8 weeks
Geotechnical Engineer: 4 to 6 weeks
Bushfire Assessor: 3 to 6 weeks
Wastewater Consultant: 6 to 8 weeks
Structural Engineer: 3 to 8 weeks
Energy Assessor: 2 to 3 weeks
Building Surveyor: 2 to 3 weeks
THE GOOD NEWS
You don't have to chase any of them. That's my job.
STAGE 3
Concept design
This is where your home takes shape: layout, form, how it sits on the site and how you'll live in it. It includes: design reviews, preliminary engineering and early builder pricing so we know the design is within your budget before we go any further.
Your feedback and decisions matter here too, and can have a real effect on how long this stage takes.
STAGE 4
Planning approval
If you need a planning permit, council has 28 days for permitted and 42 days for discretionary applications.
STAGE 5
Documentation + permits
Interiors, selections and the full drawing set your builder prices and builds from.
A building surveyor then reviews it all before the permit authority issues the building and plumbing permits.
Time so far: often a year or more.
THEN
The build
Your builder starts when their schedule allows, then works to their own program. That's why I encourage builder and trade input early in the design process.
All up: an estimated 18 months to 2 years, from first enquiry to moving in.
A comprehensive, thoughtful approach takes longer at the start, but it's worth it.
Time spent before construction gives you a resolved design, better documentation, a more accurate building contract and fewer variations on site.
I design the building and interiors together, coordinate the consultants and approvals and keep each stage clear, so you always know what comes next.
Not every building designer handles the whole process. If yours doesn't, that time doesn't disappear. It just lands on you.
If you're thinking about building in the next 12 to 18 months, now's the time to get in touch.
Frequently asked questions
-
Good building designers are usually booked months ahead, because each project needs focused design time and they're working on several at once. A wait of three months or more is normal. Reports like a site survey or soil test can often be ordered during that time.
-
Most new homes need a site survey, soil test, structural engineering and an energy assessment. Depending on your block, you may also need bushfire, landslip, wastewater and stormwater, or natural values reports. Your building designer should tell you which apply and coordinate them.
-
Once your concept design is finished. Builders have waitlists too, so getting into their pipeline early, and getting early pricing, keeps your design on budget and avoids a long wait at the end.
-
Sometimes. A volume builder can often deliver a standard design sooner, and for some people that's the right fit. A home designed around your site, your budget and the way you live takes longer to resolve, and that time is where the value is.
-
Every client is different and every brief is different. Things take longer when:
the site needs extra reports (bushfire, engineering, wastewater, heritage)
the scope of work changes partway through
feedback or approvals are slow
It all adds up.
