"The home is in an ideal situation for us, between the Mount and the shops at Fashion Island and Bayfair. It is quite close to Papamoa Beach."
Mr Middleton said knowing their home was high-quality was important.
"All the Coast houses are architect-designed and approved. The builders are first class and the area in my view is just magic. For the amount of work they have done, we found the price very reasonable."
Coast Papamoa Beach developer Steve Short said he had been watching the market for a few years and it had now reached the development's price point.
"It's a master plan development of seven neighbourhoods and all of the houses designed there will have architectual flavour."
The development has strict design standards and a select group of approved builders. Prices start at $570,000, with the most expensive house sold so far at $1.4m.
"[Our market] is people who want something a little bit different, a place where their children can come and stay and go to the beach and have guests over but the homes are usually just for a husband and wife," said Mr Short.
