Mr Scott was known for his woolshed and whare concepts, combining cathedral ceilings and matai woodwork.
Mr Scott's own involvement in the building was very hands on, she said.
"He did a lot of work for us, very late at night. He'd phone and ring about 10.30pm and say are you home and then just turn up in his 1800. He loved coffee, so we had to get jars of coffee in case he came.
"It was very special, we believe this is a 'true' John Scott.
"Our children grew up here, they had a lovely time with their friends. It was just such a lovely house to come home to.
"It has a lovely ambiance - it's something you can't describe, it's very special. "It is with a huge lot of sadness that we will be leaving."
However, a hip injury to Mr Arrowsmith meant the John Scott-signature circular staircase in the house was too much to handle.
Listing agent Amy Waterworth from Harcourts said it was "very exciting" to be able to list the property, which contained all John Scott's signatures.
"It's got the pivot doors, the matai panelling and the block work. This one they started building in 1979 and it was built in 1980 and it is in incredibly original condition - nothing has been altered.
"It's all very functional as well."
The house also featured an open fireplace handcrafted by Mr Scott.
The property would be sold by auction at Harcourt's Hastings office at 12.30pm on March 7.
