The four old sheds at the back of the facility were demolished by a group of 20 members earlier in the week.

The plumbing for the new sheds is soon to be constructed and the foundations poured for the new facilities, Dubbo Men's Shed member Phil Knight said.

"They will be used for metal work, fixing lawn mowers and whipper-snippers, welding and other projects," he said.

"We will have a big general service area undercover for bigger projects that the men will work on."

The work sheds will come complete with a metal lathe donated by Ross Tuckey.

Mr Knight said the new facilities would allow for Dubbo Men's Shed to complete more projects.

"There is a need and we are getting active men coming in," he said

"The end result is going to be not only a better facility but it is going to benefit the community as it will allow us to expand."

"Other groups can also use our facilities."

Mr Knight added that Dubbo Men's Shed was looked to for advice by other groups starting up.

"This shed is used as an example of how to run a men's shed," he said.

The members of the shed will participate as much as they can in the construction of the extension.

"We are hands on and have done all the demolition," Mr Knight said.

Part of the funding for the sheds has come from Troy Grant while the workshop of Dubbo Men's Shed also raised funds for the extension.

"It will probably cost us $20,000 to $25,000 hopefully, Mr Knight said.

The local businesses that are going to build the extension have offered the Dubbo Men's Shed a "good deal", according to Mr Knight.

So far Custom Steel Framing will provide the framework for the extension, Metroll will provide sheeting, Hansen Concrete the concrete mix and Bruce Blackman will do some plumbing for the facility.

Mr Knight, on behalf of Dubbo Men's Shed, thanked Dubbo City Council for their help to develop the new sheds and the businesses that support the group.
