The extensions at Cooma's Raglan Gallery and Cultural Centre are taking shape.
Construction began on the 144 square metre building extension in July by local building company Full On Constructions.
There has been significant progress on the extension with bricks already being laid for the walls.
It is still on track for completion by Christmas this year, despite encountering a delay early on with significant excavation required due to large amount of rock below the site.
The additional work cost an extra $29,000, which had been set aside by the Gallery for contingency.
The money was going to be used to fit out the new building.
Director of the Gallery Cherie Booker said another $30,000 would make the building complete.
She said many people had already made generous donations such as $1,000 last week and members were giving extra when paying their fees, which the board were very grateful for.
A cocktail party and art auction fundraiser held in August also earned the gallery $5,000 which will go towards the building.
She said donations were tax deductible.
The project, costing about $300,000, will see a new building constructed at the back of the heritage gallery.
It will be a modern building, with flexible hanging space for larger artworks, and storage space.
