Back in 1990/1991 Amanda realised her vision, moving into this three-storey townhouse that she describes as "a circular form that winds up through a cube".
It won her a 1991 New Zealand Institute of Architects' Award and earned her design magazine kudos, too, for the form, shapes and punches of colour that defined her style.
Her curved stairwell reflects her love of the fluid beauty of Parisian apartment staircases.
"I love the stairs and the way they move up through the house with a real sense of ease. They kept me fit, too."
Kevin Ross, a customs broker, remembers his first trip up these stairs 10 years ago. "I could hardly contain myself when I saw the views of the sea from the living area and it just got better and better the further up I went."
The house is still original, although Kevin has painted out much of Amanda's vibrant tones in the stairwell, cooling it down alongside the white walls in the first-floor living areas, the mid-level bedroom and the upper second living area/office.
The kitchen/living area has the original polished concrete floor and the low-slung wood burner with a flue that heats the upper levels during winter. Other eye-catching features include Amanda's folded stainless steel wall-mounted kitchen shelves and her two orange and yellow wall-mounted lights. Kevin's touch is his island bench on castor wheels that he moves to the edge of the deck for year-round entertaining.
On one side, the deck is framed by a shade sail that was Amanda's reference to a windmill in her concept.
On the other side, the mature trees of landscape architect Trudy Crerar's Zen entry garden behind a curved stainless steel screen complete this urban/harbour outlook.
During his happy years here, Kevin gathered a few thoughts on how to make this place even better, including turning the large bedroom into two separate bedrooms accessible via a door replacing the hall linen cupboard.
In response, Amanda suggests extending the bathroom and building a dressing room for just the one bedroom.
It's a reflective thought fresh from the eye of the architect, whose London practice, AR-Urbanism, is about designing the likes of 400-home neighbourhoods complete with traffic movement and pedestrian flow - all elements she has brought together on this pocket-sized city site.
