Add a Second Storey and Grow Without Leaving Home
When you love your location but need more room, building up is often the smartest way to grow. At Blythe & Watchorn Builders, we design and construct second storey additions that give Hobart families the extra bedrooms, bathrooms and living space they need, all without sacrificing the garden or moving to a new suburb.
Going up is one of the more complex builds we take on, and it's exactly the kind of work our team thrives on. From assessing whether your existing home can carry the load to weatherproofing while you live below, we manage every structural and logistical detail so the process feels considered and calm from start to finish.
A Careful, Considered Approach to Building Up
Every second storey addition begins with the structure. Before any design is locked in, we coordinate a structural engineer to assess your existing foundations and frame, so we know early what your home can support and what strengthening, if any, is required. It's a step that protects your budget and your timeline, and it means no unwelcome surprises once work is underway.
From there, we handle the full scope: council and planning approvals, temporary weatherproofing, framing, the new staircase that connects your two levels, services and the internal fit-off. Backed by more than 36 years of experience and multiple HIA Awards, we keep you informed at every stage and work to minimise disruption to your household throughout the build.
Why Build Up
The Benefits of Going Up in Hobart
With land in Hobart at a premium, a second storey lets you add significant space without extending your footprint, keeping your yard, garden and outdoor living intact.
An upper level is also the perfect opportunity to capture Hobart's views and light, whether that's the river, the mountain or the city, from a vantage point your single-storey home simply can't offer.
Done well, a second storey addition adds real value to your property and reshapes how your whole home works, creating a natural separation between living and sleeping zones that suits growing families beautifully.

FAQs
Frequently Asked Questions
How much does a second storey addition cost in Hobart?
As a guide, budget from around $250,000–$400,000+ depending on size, roof design and whether your existing foundations need strengthening. We provide a detailed quote up front so you know exactly what you're paying for.
Can my house support a second storey?
Not every home can. It depends on your existing foundations and frame, so a structural engineer needs to assess this before design starts. We coordinate that assessment as part of the process so you know early, not halfway through.
How long does a second storey addition take?
Most second storey additions run four to seven months on site, depending on design complexity and staircase placement. We build a detailed schedule and keep you updated the whole way through.
Can I live in my house during a second storey addition?
Often yes, especially in the earlier stages when work is mostly external: scaffolding, roof removal and framing. The disruptive part is usually the staircase install and connecting the two levels. We plan around this to keep the impact as low as possible.
Is a second storey addition worth it over extending outward?
If you're short on yard space or want to keep your garden, going up makes sense. It's generally more expensive per square metre than a ground-floor extension, but you gain space without giving up your block. We'll walk you through the real numbers for your property.
