Ian Webster says he was careful to ensure his new house in the heritage suburb of St Marys Bay would not be a concrete and glass bunker.
Responding to the criticism about the house at 38 Hackett St, Mr Webster said it was inspired by a 1945 Barcelona building and was sympathetic to other houses in the neighbourhood.
"We certainly don't think it detracts from the area any more than some of the bungalows around there that are in a sad state of disrepair," he said.
Hackett St resident John Field has called the house a "design monstrosity". Adrian Duff, who lives across the road, said the two large rectangles stuck out "like pimples on an otherwise lovely landscape".
The house is one of four new houses in inner-city heritage suburbs highlighted in the Herald - all approved by council architect Garry Glasgow - which have provoked strong feelings on both sides of a heritage debate.
