How building another storey can add priceless value

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

Bungalows and state houses are often ideal candidates for this type of renovation. Be prepared for costs around $4,000 to $6,000 per square metre and remember to account for the ground-floor space you will lose to a new staircase.
