David and Kim Williams felt a strong sense of historical responsibility when they bought their Mount Kembla cottage 15 years ago.
Their home at 307 Cordeaux Road, next to the Mt Kembla Soldiers & Miners Memorial Church, was a quaint little cottage yet they decided to pull it down due to its poor condition.
The Williams' rebuilt the house using reclaimed materials, retaining one important feature: an original sandstone fireplace which was operational around the turn of the century, and possibly before that.
Kim Williams said she was unable to put an exact date on the construction of the original house but photos of the town in 1902 - shortly after the mine disaster - show the house in its first incarnation as a one-room cottage. The pair began rebuilding the house in 2000.
"We used the same footprint, the same facade, really the same everything we could do and then extended at the back which was also in keeping with the main house," she said.
"Basically it was an original four-room cottage when we bought in 1999 but when we were dismantling it we found that one room had planks not floorboards and that was the room attached to the fireplace.
"We've gone back and looked at photos and found evidence of when it was a one-room cottage and when it was expanded they just built around that and made it more like a four-room cottage."
Mrs Williams fell in love with Mount Kembla after her family bought another property in the village 25 years ago.
"This house was always going to be a bit of a project," she said.
"It was that responsibility of wanting to make sure it was retained as an old house and appearing as an old house in the village," she said.
"To me Mount Kembla has always been a miner's cottage place and we didn't want that to be lost. We felt we had a historical responsibility."
The pair stripped an old house in Helensburgh, taking out its lining boards and floor boards, to be re-used in the Mount Kembla house.
The Williams have put their three-bedroom home on the market with Bevans Real Estate.
Listed with agent Andrew Hedley, the house will go to auction on site on Saturday, May 24, at 11am.
