"A lot of the design is really subtle and you don't really know why it works but it just really works," says David.
Although the home already had underfloor heating, Mel and David added heat pumps upstairs and even had one installed in the internal-access garage, which was handy when David was using it as his workshop.
Mel says, "We are used to living in LA where it's a dry climate and we really wanted a house that didn't have any dampness."
Thoughtfully designed by architect Peter Hill, the home was built about eight years ago by builder Craig Swney. Craig had removed the original house and had this home designed so it is tucked down on the site and follows its contours.
"It is very discreet from the street, which is what we liked about it," says Mel. "And it is quite an elegant solution to the site."
Screened from the street by a hedge, the property has terraced garden beds and a courtyard out front. Jasmine twines around this area, which features beds of vegetables.
"I like having the vegetable garden out here because I'm coming and going all the time so I see it all the time and I look after it," says Mel.
A double-height entrance way with glazing either side of the oversized front door gives a sense of light and space, a theme that is continued throughout the home courtesy of a high stud and open-plan living areas with extensive glazing covered in UV film.
At the front of the home is Mel's work room (or a fourth bedroom) and on the opposite side of the hallway is a media room with built-in bookshelves.
Past the bathroom and laundry, the house opens up into a dining area and family room/kitchen which are arranged in an L-shape around a sunken lounge. A double-sided gas fire sits between the dining area and the lounge. The U-shaped kitchen has plenty of workspace with stone benches on three sides, culminating in a large breakfast bar. The kitchen/family room and lounge open to the north-facing backyard, which has terraced gardens and a covered patio overlooking the swimming pool.
"It's a great house for entertaining because it has such an easy flow outdoors," says Mel. "Our friends are going to be very sad when we leave."
Upstairs there are three more bedrooms and two bathrooms, one an en suite to the master bedroom, which has a walk-in wardrobe and a balcony with views to the north and west across the neighbourhood.
With children living in the US and Britain, Mel and David are selling up and looking for more of a lock-up-and leave property so they can travel.
"It's a huge dilemma," says Mel. "We love our children but we love this house, too."
