This property in Longbeach sits right on the beach front and is designed to capture the breath taking 360 degree views of the ocean and the neighbouring golf course. The home has a very open plan living area on the second level which is the main living space. 

The ground floor has 3 bedrooms a family bathroom and Master bedroom with en-suite. Every square meter has been carefully considered in this home, resulting in a compact but highly functional space. These eHaus owners are one of our lifelong supporters, and we love that they are passionate about their home and building with us. 

A previous homeowner had called the property 'The Lighthouse', resembling a Lighthouse on the beachfront and although it wasn't very old, didn't meet the needs of our homeowners for a comfortable healthy place to live, so was replaced with this beautiful eHaus and given the new name of The Lighthouse II. 

"We chose eHaus because we knew that this was a way that we could have the comfort and the warmth… also having every room of the house warm…often New Zealanders say to me, well our living room’s warm, but then they go to the bedroom, it’s cold, so we chose eHaus because that was a solution to that." – Harry and Mary

At first we were skeptical. Can we really have a house that stays between 20 and 25 degrees all year round without any heating? Actually, that is what the reality is. We have no regrets. The house has lived up to its promise. When the temperature dropped to single digits in Spring, friends who built at the same time as we did – so the insulation, double-glazing and so on, were all up to spec – had to turn their heat pump on. We were still waking in the morning to 22 degrees inside. And it’s not just the warmth of the house. It’s also the evenness of the temperature throughout the house. We had a wood-burning stove in the house we first lived in and yes, it was very cozy in the living room. However, when we got up in the middle of the night to go to the toilet (which Gold Card holders like us tend to do) it was cold! But not in our eHaus. It’s the same temperature in every room!
