They’re 24 years old, count their mothers as their only employees, and claim to have finished more homes in inner Christchurch than the Government-backed rebuild effort.

Meet Matthew Horncastle and Blair Chappell, co-directors of upstart property development company Williams Corporation, named so because of their shared middle name.

Last year, the company built 40 homes in the inner city and surrounding suburbs and sold 80, with an overall sales value of about $35 million.
