What to Consider Before Building a Small Second Dwelling in Castlemaine

Castlemaine properties often include planning overlays and site-specific constraints that influence both design and approvals.

While every site is different, common factors include:

• Heritage overlays in parts of town
• Bushfire Management Overlay (BMO) requirements
• Site access and slope
• Services connections and capacity
• Orientation for passive performance

Understanding these early allows the design to respond appropriately, avoiding unnecessary revisions and delays.

Good outcomes come from getting the fundamentals right at the beginning.
