What are the best Gold Coast suburbs for duplex development?

Gold Coast duplex / dual-occupancy development concentrates in three corridors:

MD1 mid-density corridor — most consistent pathway - Miami (4220) — proven dual-occupancy precedent, lots typically 600-800m², MD1 zoning supports the standard duplex pair. - Labrador (4215) — affordable RD2/RD3 entry, dual-occupancy pencils on 700m²+ lots clear of storm-tide overlay. - Ashmore (4214) — middle-ring LDR/MD1 mix; consistent council appetite for duplex in MD1 sub-precincts. - Mermaid Waters (4218) — canal-frontage RD/MD1 commands premium end-product values.

MD2 premium corridor — highest end-values, highest entry - Burleigh Heads (4220) — MD2 zoning supports dual-occupancy AND townhouses; end-values $1.4M-$1.9M per dwelling. - Palm Beach (4221) — MD2 corridor with gentrification tailwind; storm-tide overlay binds many lots. - Mermaid Beach (4218) — premium beachside MD2; smallest pool of compliant sites.

Hinterland edge — emerging plays - Mudgeeraba (4213) — larger LDR/MD1 lots, hinterland character, strong rental demand. - Pacific Pines (4211) — affordable LDR with secondary-dwelling permission and consistent yield.

What to filter for: - Frontage ≥18m for code-assessable side-by-side duplex. - Storm-tide overlay clearance (lifts every slab if binding). - Character precinct status (Mermaid Beach, parts of Burleigh — can constrain bulk). - Slope <1:8 (above adds expensive retaining).
