The wall, which stands a metre high and is a half metre wide, was the first Mr Dunn had built in Masterton after constructing a similar wall in Martinborough and in Greytown and building the greater part of a Wairarapa residential home from stone.
Mr Dunn emigrated to New Zealand from Britain in 1974 to work with Canterbury Stone on the Beehive and the BNZ Bank in Wellington. He moved to Masterton about 14 years ago from Stokes Valley.
Mr Dunn learned his trade, in which his Masterton-based son Peter is also working, at a stonemasonry company called Thorntons in his home city of Liverpool.
He had completed 50 years in the trade before he retired and earlier said there are few genuine stonemasons still at work in the region.
Mr Dunn was to this week start on another stone wall, also to be fashioned from graywacke boulders, that will grace the Gateway Motor Inn a couple of doors down from the Wilkinson property on High St, he said.
The wall would be smaller and he also would build at the site a stone fountain surround and matching seating.
