The owner-builders have opted for a timeless design at 8 Petersen Ave, Southport.“They’re all very different, we don’t like the cookie-cutter approach,” Mrs Gillespie said. “All three pairs have a different design as I think that adds value to the area.” The duplexes are located within The Southport School precinct and offer easy access to nearby parks, cafes, childcare and Ferry Road Markets.

The kitchen features Smegg appliances and soft close cupboards.The couple has now shifted their attention to a new house build nearby in Southport, but would love to remain on Deauville Dr.“It’s so quiet here and suits us perfectly,” Mrs Gillespie said. “The next move is always an unknown when you marry a builder.”The duplex is being marketed by Glen Williams, Ray White Prestige – Surfers Paradise.
