A home belonging to the family of rich-lister and Lockwood Homes co-founder Jo La Grouw Snr is for sale.
The late Mr La Grouw built the family home, a Lockwood, in Rotorua in the early 1950s as a prototype for the company that built using a method of interlocking timber.
The design has since sold around the world, including to Russia and the Middle East.
Mr La Grouw and his late wife, Gonda, made the property their home for more than 60 years after emigrating from Holland with their five children.
He and his business partner, Johannes Van Loghem, pioneered the building system.
