Cost, rent, and value — what actually moves the number
Indicative build bands only. Your quote depends on site, structure, bushfire rating, services, and finishes — use this page to understand drivers, not to budget to the dollar.

Named house-type imagery and a typical floor plan sit on the main SSD overview— this page stays focused on cost drivers and tiers below.
Indicative cost tiers
Same 60 sqm cap — different structural and fit-out choices change the total.
Tier 1
Compact compliant
Simple footprint, modest finishes, easier site. Rough band $70k–$135k.
Tier 2
Rental-ready
Better thermal performance, harder-wearing materials. Rough band $90k–$169k.
Tier 3
Higher spec / harder site
Steeper slope, retaining, or higher-end architecture. Rough band $122k–$168k.
Rent and longer-term value
Rental demand on the Peninsula and in greater Victoria has been tight in recent years — but vacancy and rent move with the cycle. Treat rent as a possible benefit, not a promise.
For many owners the value is mixed: family flexibility, a separate workspace, and sometimes income — plus how a documented, compliant second dwelling affects resale compared with an unapproved structure.
