How building another storey can add priceless value

Adding a second storey, or "popping the top," can create valuable space and views. Before starting, consult an architect or structural engineer to check structural feasibility and council rules like height-to-boundary restrictions.

Bungalows and state houses are often ideal candidates for this type of renovation. Key considerations include matching the new style to the existing home and sacrificing ground-floor space for a staircase. Expect costs around $4,000 to $6,000 per square metre.
