What moves the price

- Services: distance to the sewer and water connection points, stormwater, and whether your electrical supply needs upgrading.
- Access: tight side access can mean extra labour or a crane.
- Approval pathway: CDC compared with a council DA, plus BASIX, bushfire (BAL) or flood requirements.
- Design and finishes: a second bathroom, the size of the outdoor living area, flooring, kitchen and façade upgrades.
- Extras: driveway, fencing, landscaping, demolition or relocating sheds.
