Sir Harold recruited former student Hamish Boyd - now a director at Jasmax Architects - to realise his vision of a quintessential bach. The silvered cedar building is as fresh as when it was built, carefully sited to capture the sun and views around the bays and across to Rangitoto.
The gently curved roof recalls an up-ended boat and deflects the prevailing winds. Sir Harold's knighthood is for architecture and acoustical engineering, so every detail in the house has been considered. Sturdy recycled timber columns, quirky stained glass and knotted rope hand-rails reflect the nautical setting.
The house was designed as a family lodge. Down a private drive with ample parking and carport, the entry is at mid-level. The macrocarpa ceiling sweeps over two levels, with carefully framed views of the sea through high windows and French doors.
The entry-level snug overlooks the open-plan dining and living areas. Deep wrap-around verandas provide year-round outdoor living, flowing on to a flat lawn with harbour views framed by pohutukawa.
The kitchen was designed as a "bach kitchen" but has delivered Christmas dinners for 30 family members. Down a curving path to the tideline is the stone boathouse. It was built after the Home Guard sliced away the point for the war-time searchlight beam.
Sir Harold remembers: "Dad saw the possibilities and we teenage boys enjoyed great summers hauling rocks, watching out for girls, and catching snapper for dinner."
As well as boat storage and launching ramp, the boathouse's flat roof is the favourite summer living spot for family and friends.
The house was designed to accommodate several generations at once, with upper and ground levels each housing two double bedrooms and bathrooms. A bunkroom with leadlight windows has delighted children, while the master bedroom captures those magnificent views with a sunny Juliet balcony. Another bathroom off the laundry at entry level is handy for rinsing off after a swim.
The house and its harbour views also appealed to tenants, including Sir Peter Blake and family, who lived there during the America's Cup Challenge. At low tide they too could have wandered along the causeway to nearby Mairangi Bay village, or pulled up a snapper at high tide.
With the original family now spread over several generations and continents, it's time to let go. Covenants on the property do allow redevelopment, but in the meantime this interpretation of the classic Kiwi bach is ready for another family to enjoy.
