Extensions
Single Storey Extensions
If your current house is becoming too small for the growing family or you are looking to add more value into your home it makes sense to go up or out rather than sell up and move. Rooms can be added on or roofs can be extended up. We will sit down to understand your needs and the direction you want to take.
The extension needs to match in with the existing building. We can make sure that the proper materials and finishes fit seamlessly in with the existing building.
We can work in with a builder of your choice or we can put you in contact with reliable builders to ensure that we work to your budget.
We are also able to draw plans for garages, carports, verandas, decks and internal remodelling for kitchens and bathrooms.

Second Storey Extensions
When comparing pricing on a second storey addition, it is important not to go by price per square metre. There are three main reasons for this: ‘Save money by adding a second storey additon’.
- Quality can vary immensely — It is important to remember that not every second storey extension builder delivers a project to the same standard. Materials, finishes and execution vary in quality, and therefore in price too.
- Every project is different — Depending on the scale and complexity, and the areas involved in the new double story addition, price per square metre will vary. Designs featuring unusual shapes and angles will, naturally, be more expensive than designs with simple square shapes. This is due to the extra building materials required, rather than any added difficulty in the execution. kitchens and bathrooms will also increase the cost of the two storey extension significantly. The average cost of a kitchen ranges from $30,000 to $50,000, and a bathroom from $20,000 to $30,000. The overall costs of a second storey addition, without rooms such as these, will be considerably less than one with.
- Every property is different — Often, the existing home will need upgrading to suit the new second storey addition. The design of the 2nd storey extension, and the way it integrates into the existing structure will ultimately dictate the extent to which the ground floor will need to be upgraded. Other factors such as council overlays, energy efficiency, bushfire zones and soil classification have the potential to impact the overall cost of the project and affect the cost per square metre.
On average, the cost of a second storey addition begins at approximately $220,000.

Our process
A process with you in mind
A good designer who produces a space-efficient and climate-responsive home can save you at least as much as the cost of their fees, by helping you reduce upfront construction costs (through efficient use of space and materials) and ongoing energy costs (through climate-appropriate design). Good design is a smart investment.
