A buyer walked into the sales office at One Redcliffe, Gardner Vaughan’s apartment project, looking for an apartment that wasn’t on the plan.

Six months later he had it. The contract was signed on 20 August for $10 million, which Century 21 Project Partners says is a record for the Redcliffe peninsula. Principal Danelle Wiseman says the highest sale she could find before it was $6 million in Scarborough, though there may be off-the-plan sales she hasn’t been able to track down.

The agency is based in Caloundra on the Sunshine Coast, with an office in Milton and a sales display office beside One in Redcliffe.

Jonathan Pattinson, head of projects at Century 21 Project Partners and lead agent on One, drew on his background in construction and sales to solve the problem, working with the buyer and Gardner Vaughan’s design team.

“He joined them together and made one large apartment and one smaller apartment, met with the client, understood the client’s needs, filled the brief,” Danelle says.

The change was significant enough that a new development application had to be lodged. Danelle says it only worked because the developer, Gardner Vaughan, is a Queensland family-run owner-builder with the flexibility to adapt.

“If they were not a developer-builder, we probably wouldn’t have been able to give this option because it would have just been too difficult to do,” she says.

Draft plans needed continual tweaking before everyone was satisfied, and Danelle credits Jonathan’s patience and construction knowledge with keeping the process on track.

“Jonathan is a model of patience, and he listens really well,” she says.

“I think the collaboration was really important, and it was that patience from all people involved that was able to see the success.”

She also credits three people from Gardner Vaughan: head designer Jordan Price, sales manager Claire O’Hara, who coordinated the collaboration, and Annika Lochiel from the design team.

The buyer is a local man from the Redcliffe peninsula who plans to move into the combined apartment as his long-term home.

Danelle says it’s the agency’s largest off-the-plan sale to date and reflects a changing Redcliffe, where average sale prices have lifted since marketing on One began in March 2025. She counts One among the projects leading what she calls a gentrification of the suburb.

“I reckon it just means your place is a leading project,” she says.
