A MOSMAN family home 15 years in the making has won a major Housing Industry Association award.

The striking house, near Rosherville Reserve and Chinamans Beach, won the HIA NSW Custom Built Home $1m to $2.5m award this month.

Judges said the beautifully-designed home showed great attention to detail throughout.

“The house shows brilliant workmanship and construction with a seamless design with simple and modern finishes showing the difficulty in construction,” they said.

The property is a year old and took about 18 months to build.

The builder was Lawson and Lovell Building Services. Architects Fitzpatrick and Partners did the concept design and Watershed did the development application and detailed design.

The three-level property includes four bedrooms, a rumpus room, garage, outdoor entertainment area which flows from the indoor living space and water views from the upper level.

The swimming pool even has a clear panel which doubles as a safety and design feature.

Homeowners Tina Tang and John Andrews, who have both worked as architects, had a lot of input into their dream home.

The couple bought the previous house on the site, where the family lived for about 15 years.

Ms Tang said they considered renovating but in the end decided that a demolition and rebuild would best achieve their goals.

“The house is modern, contemporary and open plan with high ceiling spaces,” she said. “It allows a lot of natural light in, particularly northern light.

“It takes on-board the principles of good design, maximising solar access. It has good shading to the west and south.

“Spaces flow well and it’s very well built. The builders put a lot of care and passion into the build; they did a really good job.

“We knew our house was special, but of course it’s always really an honour and a great surprise to win.”

Ms Tang said her son, 15, and daughter, 20, also loved their new home.

“I don’t know if it’s such a good thing having built our dream home now, because I don’t know when they will be leaving,” she laughed.

“I think the best thing they love is the fact that they have huge bedrooms and their own bathrooms.”
