Concept design for a fictional businessReal estate

Harbourline Property

Real estate agency, Mosman NSW

The concept

“The Harbour Folio”

Homes presented the way a private press presents a limited edition: numbered plates in sandstone mounts, printer's marginalia, and addresses withheld until you ask. Nothing is stickered or shouted. The confidence is in what is left out.
