A home extension is about more than just adding space. It’s about creating a home that works for your lifestyle today and in the future.
Benefits of a Home Extension Hobart include:
Most Hobart home extension projects take several weeks to a few months to complete, depending on the scope and complexity.
At Nomac Built, we keep things clear and predictable with straightforward scheduling and regular updates.
Here’s how we manage the timeline:

Layouts, specification sheets and full breakdowns, so you see exactly what you are getting before anything starts.
From plumbing and waterproofing through to tiling and fit-off, every stage is run by our licensed team.
Zak and Tom are on every job. No account managers, just the people who quoted your renovation delivering it.
A fixed schedule before we lift a tool, and the discipline to hold to it. No creeping scope, no surprise invoices.
Look for extension builders who'll be on site themselves, not just quoting the job and handing it to a project manager. Extensions involve matching new structure to an existing home, so experience with older Hobart housing stock matters too - things like tie-ins to existing rooflines, matching floor levels, and working around load-bearing walls.
At Nomac Built, Zak and Tom manage every home extension personally, from the first site visit through to final handover. We also recommend checking that any home extension builders you're considering provide a clear, visual quote so you know exactly what's included before work starts.
Yes. One of our strengths is transparency. If you've received a quote elsewhere and you're unsure about what's included (or missing), we're happy to help you review it. We've seen too many clients caught off guard by vague or incomplete quotes, and we'd rather help you make a confident decision than watch you get stung by something that should have been spelled out from the start. This applies whether you're comparing quotes for a bathroom renovation, a home extension, or a custom new build. Scope and inclusions vary a lot between builders, and the detail matters.
No plans yet is a very normal starting point, particularly for new builds and extensions. We can recommend designers and drafts people we've worked with and trust, or collaborate with whoever you've already engaged. The earlier we're involved, the more useful we can be - we often pick up practical issues at the planning stage that would have cost time and money to fix once building started. Whether you're working up ideas for a custom home build or a home extension, we're happy to have that early conversation.
Yes, we handle all the subcontractors for your project. We coordinate a trusted group of local trades who share our focus on quality and reliability - plumbers, electricians, tilers, and everyone in between. You won't need to chase anyone or manage sequencing. That's our job, and keeping trades moving efficiently is one of the biggest factors in keeping your project on time and on budget.
It depends on the scope and complexity of your project. A bathroom renovation typically takes 3 to 5 weeks on site. A home extension will generally run between 8 and 20 weeks depending on size and structural requirements. A custom new build is a longer commitment - most run between 6 and 18 months from breaking ground, depending on design complexity, approvals, and site conditions. Whatever the project, we provide a realistic schedule before work starts so you always know what's happening and when.
