The cost of stamp duty in Sydney on the purchase of a property valued at $2M as of July 2023 is $95,818.50 – this could buy you a new Kitchen and Bathroom.

Should I build up or build out?

If you need some more space in your home there are generally two options; either extend or build a first floor addition.

Ground floor extensions are ideal if you have the space to extend outwards and are generally cheaper to build. They are also a better option for older people because there are no stairs to negotiate.

You can also create a balance between outdoor and indoor entertaining spaces. Extensions also allow you to open up your home and are great for adding bedrooms, a master bedroom suite, bathroom, and working from home areas.

There are two paths you can take when extending your home. Either choosing contrasting and complimentary style, or design the new rooms to match the existing style. Making it look like it’s always been part of the original home.

 First floor additions are a great option if you have limited space and are a common renovation for people looking to add large new living spaces to their home.

These generally are a better option for smaller residential blocks and great to capture the breeze or gains views that an extension won’t achieve. They are the most effective way to give your home a lot more space. 



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.


Clients often come to us with a set of sketches that they have drawn or located on the web – which is great because it shows they have considered how they feel the space will work for them. We take these sketches and review for both compliance and functionality. We offer feedback and then move forward once the client has provided direction.

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