'Treehaus', located at 39 Morrison Avenue, Coledale sold for $2.5 million

Sitting on 10,000sqm, 'Treehaus', is located at 39 Morrison Avenue.

The house sits within an Illawarra Escarpment Blackbutt Forest, with land to the south available to clear.

It sold prior to auction, after just a couple of weeks on the market.

Selling agent, Trever Molenaar from Molenaar + McNeice said it sold to expat Australians who are living in France.

"We had a few people negotiating - there was a number of people interested," Mr Molenaar said.

"There was a handful of really interested parties, which is why it sold so quickly."

This also included inquiries from Singapore and Sydney.

Owner Kieran Jones purchased the land in mid-2016.

He soon set about building "an environmentally-friendly dwelling that blended into the Illawarra landscape".

"I think that was achieved, as it's really low impact," he told the Mercury recently.

Construction of the five-bedroom, two-bathroom house was completed in March 2018.

Mr Jones said there were a series of features of the home he enjoyed.

"The facade is an aluminium cladding called Stryum, which is a non-combustible, recyclable, stylish (material)," he said.

"I also like how the home sits into the landscape; the elevated positioning of the house within the Illawarra Blackbutt Forest."

Mr Jones said the 'Treehaus' name was derived from the home being suspended "quite a few metres" into the forest.

"The name is because it's effectively a tree house when you're inside, as you're amongst the trees there... And it's a luxurious tree house at that."

Mr Jones said a second dwelling was permissible under the Wollongong LEP.

Also, 'tiny homes' and moveable dwellings can be utilised on the land.

Mr Jones said with this project completed, he wanted to sell 'Treehaus' to "someone that can make good use of it".

He also said he planned to stay in the area.
