After 25 years of high-end fashion Collette Dinnigan has finally turned her creativity to her love for interior design and hotels.

Working with Bannisters by the Sea, a coastal boutique hotel a five-minute drive from Dinnigan's NSW South Coast country retreat, penthouse suites 29 and 30 have been completely renovated and reimagined.

Collette's inspiration was to capture the seaside coastal elegance of the suites in a relaxed and comfortable environment, while retaining her strong feminine aesthetic complete with luxury finishes.

The first one hundred guests will receive a limited edition Collette Dinnigan candle made in France.

Penthouse Suite 29 is instantly relaxing with the sound of waves crashing. Walking into the living room, past the kitchenette and large trestle style table, you have uninterrupted ocean views with comfortable linen sofas, handprinted cushions by textile designers such as Kathryn Ireland, Penny Morrison and Carolina Irving, a wool rug by Vaughan, a gas fire place with marble mantle, oak wooden floorboards, wooden shutters and doors.

The bedroom features Schumacher fabrics, brass Aerin Lauder wall fittings and a chair Collette bought in the South of France hand covered in velvet.

The bathroom is real luxury featuring hand made vanities with Carrara marble tops, Perrin & Rowe tapware, a sizeable bathtub and shower, and heated floors. There is also a separate powder room.

Australian photographers and artists who have an emotional connection to the water are featured throughout — such as Murray Hilton and John Witizg's 1970s surf nostalgia.

Both suites have a collection of botanical and coral sea life sourced from the French markets, as well as charts from Collette's family's sailing journeys across the Indian Ocean.

The balcony offers customised cane furniture in a relaxed setting for two.

Penthouse Suite 30 is now accessed through a private hallway adorned with John Witizg's nostalgic Australian surf photography from the 1970s.

Walking past a kitchenette and large dining table into the living room you have stunning ocean views towards the east, and north towards Jervis Bay. Comfortable linen sofas, handprinted cushions by textile designers such as Kathryn Ireland, Penny Morrison and Carolina Irving, wool rugs by Madeline Weinrib and Robyn Cosgrove, a gas fire place with marble mantle, wooden oak floorboards, then past wooden shutters and doors onto an extended balcony with antique Indian day bed filled with cushions, two sun lounges and customised cane furniture.

The bedroom features Schumacher fabrics, custom lamps and a chair Collette bought in the South of France hand covered in Belgium linen.
