Extensions and Home Addition Plans in Sydney

Two storey extension and attic conversion


Have you run out of space and storage?

Do you wonder how an extra room or two could improve the flow and practicality of your home?

With our home design expertise and detailed know-how of the Development Application process, we can help with attic conversions, home extensions, and additions.

Should I Build Up or Build Out?

When you want to create additional areas in your home, you typically have two options: build out or build up.

Adding extra rooms to the ground floor or building a second storey addition can give your property’s value a great boost, not to mention all the extra space for a growing family.

Extending by converting an attic or adding a new level might create more room and privacy for growing children. It may also provide better views to the surrounding landscape, all without reducing the outdoor space that Australian families love.

If you want to expand your living space without increasing the footprint of your home, building up is the option for you.

Building out typically involves adding a room at ground level, which is one of the most popular types of additions. These options increase the footprint of your home by extending the house’s perimeter, which offers minimal disruption to the rest of the home.

The Design Plus Drafting team can create a design that suits your needs, whether it’s going out or up.

The Extension and Addition Design Process

First of all, we need to listen to what you are wanting to achieve. What is the problem you face? What is your ideal scenario? What are your ideas, if you have them?

Together we can create a plan that will achieve your goals with the least expense. If you have a set budget, we will work guided by that figure in our design concepts.

Our house extension design will be sympathetic to your existing home, ensuring a cohesive look, which will help enhance the resale value.

Design Concepts, Plans Drafted, Documents Submitted

When you are entirely happy with your design concept, we can draft the plans for your local Sydney council and submit them for approval.

We have experience working with every council. Our team is efficient and makes sure the council has what they need to approve your Development Application or get you a Complying Development Certificate CDC.

Did we mention we have fixed fees? No budget blowouts with us.
