"Steve is a wonderful man, superb to deal with and he has used all local tradesmen. They have done a magnificent job ... the work is top class, there have been no shortcuts. It is absolutely beautiful."
The two apartments, one upstairs and one down, are quite different, he said.
"One is in period design and the other is contemporary style."
Mr Watson said the council was seeking specialist advice on the building to help Mr Quinn.
"For instance, we'll be talking to the fire service and ensuring there is nothing in this building that will put people at risk.
Mr Quinn said, as far as he was concerned, the building was now a perfectly serviceable heritage build.
"It will contribute to the function of the Marton CBD for at least the next 100 years," he said.
Mr Watson said council was helping with discretion of some consenting costs and a possible rate reduction as the building work continued.
Mr Quinn has also written to the council for help.
"We are hoping that central government assistance also may be available," he said.
Mr Watson said council would be pulling out all the stops to help Mr Quinn.
"I will also be talking to Heritage Minister Maggie Barry and will try to persuade her to come to Marton and see this beautiful heritage building first-hand," he said.
