The expansion plans also provide a creative learning centre for school students, public cafe and accommodation wing for 64 people.
Bundanon Trust chief executive Deborah Ely said the trust had been trying to find the resources to install ember suppression systems for some time.
“We have just been told about the funding and are really ecstatic,” she said. “If it had been in place it would certainly have given us more if not total confidence in facing this year’s threat.”
The Boyd Homestead and Arthur Boyd Studio are on the national heritage register, Ms Ely said, and were irreplaceable. Artworks that were displayed in situ would return to Bundanon at the end of this fire season, while most items would remain in safe storage off-site.
Mr Fletcher said ember suppression equipment worth $300,000 would be installed as soon as possible to protect the property from bushfire threat. It is expected to include automatic ground and roof sprinklers and hose reels, backed up by a dedicated water tank and pumping system.
“The new system will make sure the Bundanon property, including the Arthur Boyd Homestead, studio, artists in residence and musician cottages, and the art collection store, is sufficiently equipped for future bushfire threats,” Mr Fletcher said.
Meanwhile, the new building works at Bundanon are to be completed by late 2021, allowing the Bundanon Trust to expand artistic programming, at a time when the Shoalhaven region is working to recover from a catastrophic fire season.
