Mr Ruby said the timing was perfect.
''We just got in the market at the right time and we're blown away with the capital gain on it.''
It was that capital gain that has given them the financial strength to build again, once again in The Lakes.
''If it wasn't for the gain we had on the house, we wouldn't be in a financial position to be able to do it, so we might as well make the most of it. Definitely the timing was good.''
Prior to moving into their own home, the couple were renting in Merivale. Building was by far the more sensible option.
''For the same price we would have been getting a 20-year-old house that would probably have needed $50,000-$60,000 thrown at it to upgrade kitchens and bathrooms, so it just wasn't cost effective. It was actually cheaper to build rather than to buy existing stock.''
The house they are living in, with Mr Ruby's daughter Ella (12) there part of the time, has three bedrooms, two bathrooms, a single garage and a floor area of 150sq m. It is on a sloping section.
They are looking at building another three bedroom house with a double garage, a floor area of about 169sq m on a flat section.
''We weren't originally looking at selling to be fair - this house was what we wanted to keep - but it was just too good an opportunity to miss.''
