Ground Floor Extensions

Ground floor extensions are not the most cost effective way of creating extra space in your home, however they can be perfect if you have the extra land to build on.

An extension of the ground floor is a great way to create additional living space, especially when you would like to open up your living areas to join the outside entertaining area.

First Floor Additions

Thinking about adding a first floor addition to your home? This is the perfect way to create extra space in your home when you don't have the land to build on, or would like to take advantage of the most cost effective solution to gaining extra space.

We have several design packages to suit the needs of a growing family: Teenage Retreat, Parents Retreat and Family Retreat. These designs are a great starting point when thinking about first floor designs and can be altered to adjust your family's needs.

Need more space but don't know where to start?

We offer an initial obligation free consultation with our in-house building designer who will discuss design ideas and the feasibility of the project within your budget.

Our services including stepping you through the whole building process from the initial concept designs, tender proposal, council submissions and issue of the Final Occupation Certificate on final completion. However, if you already have plans finalised, we are more than happy to help with your build.

We are passionate about working with you to achieve your desired outcome.
