"We had a meeting of neighbours in June and only two houses were not really damaged - ours and a light, timber-framed house."
Brick cladding peeled off adjacent properties and tile roofs were lifted by the big quakes and had not returned to their proper place.
The Christisons are in the process of selling this home to build a new place on a lifestyle block and he said an independent structural engineer had described the house as excellent and in a very good condition.
Mr Christison is the engineer in charge of Christchurch City Council's water and waste water reticulation, so he has witnessed first-hand the damage caused to other buildings.
"Our family has always felt very safe in the house - even the kids. We would not build anything else but a Lockwood in New Zealand."
Lockwood general manager Bryce Heard said none of the Lockwood homes inspected post-quakes had anything more than minor damage and the local franchisee was being inundated with inquiries now insurance claims were starting to come through and Christchurch residents were starting to rebuild.
