For Home Extensions Hobart

What to expect

Increase the size of your current home with a seamless extension

Extending your current home or adding another level can be a great way to increase your lifestyle options, without having to move house.

Especially as your family grows and older school leavers plan to stay at home longer.

Plus building an extension onto your existing home can be an affordable and effective way to upsize, when compared to the other options.

And in many cases, you’re able to continue to live in your home as we extend it.

Whether you have some plans ready to go, or you’d like to discuss your vision and tap into our experience, please don’t hesitate to get in touch.

FAQS

Frequently asked questions

Do I need a building permit for a small extension?

In Tasmania, almost all structural extensions require council approval, especially when adding to the back of your house or building upwards. Even if you’re just getting started, we’re happy to join the initial conversations with your Architect or Building Designer to help you move in a practical direction.

Yes, absolutely. We have extensive experience sourcing local materials and seamlessly blending in old features with the new extension.

Every home extension is different. Some might require a new ground slab, whereas others can involve reinforcing the structure of your current home to build upwards. As a guide, a home extension can take anywhere from 6 – 18 months, depending on the complexity and scale.

Generally speaking, we project manage and build the entire extension once you have an approved set of plans. And we welcome earlier conversations to help add practical value to the design process.

In most cases you’ll be able to stay in your home while we extend it. However, there might be times when certain features or rooms are out of action, but we’ll always coordinate this with you and help minimise disruption to your daily routine.
