What You Need to Know About Home Renovations
Renovations carry more unknowns than new builds. Working with an existing home means uncovering hidden conditions, ageing materials, and structural limitations during construction. Early planning, transparent pricing, and clear communication are critical to managing these complexities properly.
The best renovations feel integrated. A well-resolved renovation should feel cohesive rather than added on. The transitions between old and new construction — floor levels, materials, proportions, and detailing — are what determine whether the home feels seamless as a whole.
Renovations can significantly improve performance. A well-planned renovation can dramatically improve comfort, functionality, energy efficiency, and long-term liveability. Upgrading insulation, glazing, ventilation, and layout often delivers the biggest long-term gains.

Frequently asked questions
Home Renovations and Extensions in Tasmania — your questions answered
How much do home renovations cost in Tasmania?+
Home renovation costs vary depending on the scope of work, site constraints, level of finish, and complexity of the existing home. We assess every renovation through a structured estimating process that reviews the existing home, identifies likely complexities early, and develops transparent pricing aligned to the actual scope of work.
Do I need an architect for a home renovation?+
For anything beyond a straightforward refurbishment, a good architect or designer is critical to achieving a cohesive renovation outcome. If you already have a designer engaged, we work alongside them early through our ABC Success Relationship approach.
How long do house renovations take?+
Timeframes vary depending on the scale and complexity of the renovation. Smaller internal renovations may take several months, while larger renovations and home extensions can take 12 months or longer once design, approvals, and construction are included.
Can I live in my home during renovations?+
Sometimes. It depends on the scope of work and which parts of the home are affected. For major structural renovations, moving out is often safer and allows construction to progress more efficiently.
What's the difference between a renovation and a home extension?+
A renovation improves or reconfigures the existing home, while an extension adds new floor area. Many projects involve both, which is why integration between old and new construction is so important.
Are home renovations more expensive than new builds?+
Per square metre, renovations can often cost more due to the complexity of working around existing structures, matching materials, and managing hidden conditions.
Can you renovate heritage or older homes?+
Yes. Older and heritage homes require careful planning, structural assessment, and sensitivity to the original architecture. We work closely with designers and consultants to preserve what makes the home valuable while improving performance and functionality.
How are home renovation costs estimated?+
Through a structured, open-book estimating process that reviews the existing home, project scope, and likely complexities early before detailed pricing is developed.
What approvals are needed for home renovations?+
Approval requirements depend on the scope of work and local council requirements. Renovations may require building approval, planning approval, or heritage considerations depending on the project.
Can home renovations improve energy efficiency?+
Yes. Renovations provide an opportunity to improve insulation, glazing, airtightness, ventilation, and overall thermal performance within the constraints of the existing home.
What should I prioritise during a house renovation?+
Structure, layout, services, and building envelope performance should generally be prioritised first, as these are the hardest elements to change later.
How do renovation builders manage unexpected issues during construction?+
Unexpected conditions are common in renovations. Our process focuses on identifying risks early, documenting issues clearly, and managing variations transparently through open-book communication and written approvals.
