New Building Designs

We have the experience, building knowledge and expert consultants required to make your ultimate dream home a reality.

Alterations & Additions

From a kitchen renovation to major alterations & additions, we have the expert building knowledge required to make your project a success.

Sustainable Design

Through thoughtful and efficient building construction, we build sustainable homes with reduced negative impacts on the environment.



A new home design will usually be one of the largest financial investments you will ever make, so you need to get it right.

Some of the core considerations in designing a new home are client requirements, planning codes, the orientation of the site, the slope of the site and suitable construction techniques.

We can guide you through the entire process to achieve a design that suits you, gets planning approvals and is ready to build.


From a kitchen renovation to major alterations & additions, these need to be planned meticulously to achieve outstanding results.

Starting with the existing layout of the house, we can design your renovation or alterations & additions to make the best use of all the available space, create a better connection between spaces and achieve results you could only dream of.



All projects are designed with passive solar design principles integrated from the design concept stage to create a comfortable, efficient, livable home.

In NSW, a Basix certificate is required for both alterations & additions and new homes.

Introduced by the NSW Government, Basix, the Building Sustainability Index, ensures homes are designed to use less potable water and be responsible for fewer greenhouse gas emissions by setting energy and water reduction targets for houses and units.
