You don’t have to move to have more space at home

The team at Habitat Additions understand that moving home can be a costly and stressful experience, especially when you are moving home to allow more space for your family. You may not have wanted to move in the first place, and find yourself exceeding the budget to create the necessary extra space.

Alternatively, you may want to make the most of some exceptional views that your property has the potential to provide but previously couldn’t with just the one existing storey.

These are just a few of the reasons for adding a second storey to a pre-existing home as opposed to moving all together.

Our second storey extensions come with a six-year guarantee, giving you the peace of mind you need with your extension. We know that adding a storey extension to a home is just as exciting as when you first moved in, so you can expect only the best service from us. Simply put, we will make your extension dreams come true.

We consult with you and listen to your requirements before coming up with a concept for the extension that you are happy with. We sort out all of the administration work with the council and then get to work on constructing your dream extension, completing the construction in a timely yet highly efficient and detailed manner.

We work with and use only the Best!


Moving home is less attractive when you have to calculate what you stand to lose, so building up has become the go-to solution for families who want more room to move, without actually having to make a move.
You may also be able to take advantage of great views that previously couldn’t be seen.

All of our work comes with our 6 year guarantee giving you the peace of mind you need. So, dream big and count on us to make it come true — it’s about your lifestyle.

We take your needs and initial ideas and then create a concept with your budget in mind. We look after all council applications and approvals and all the stages of planning.

We then build your dream home extension or renovation. You get to stay in the neighbourhood you’ve grown to love!
Habitat Additions offer a free, no obligation consultation. When we meet with you we will develop a brief that will include your budget and what you expect to get for the money you spend.

Because Habitat Additions are a full-service, concept-to-completion home extension specialist, we are confident the guide price we give you will be close to the real cost to design and build your new extension.

Once we have the necessary information from you and the building contact has been signed, all known costs are included in the price.
