Chairman Alastair Smithies said the group's membership has increased over the past year from 45 to more than 60.
"It's providing a source of fellowship for older and mostly retired men. We try to accommodate men of all abilities," Smithies said.
"They come from all walks of life, retired farms to builders, joiners, school teachers."
Construction of a $160,000 shed on the group's site, leased from the Selwyn District Council and next to the Lincoln Event Centre on Meijer Drive, is under way.
Smithies said half of the new shed will be workshop space. It will mean the current engineering area, crammed into a corner of the existing workshop, will be able to be moved into its own area.
This would make it easier for members to balance the two activities of woodworking and welding together.
"Woodworking and welding don't mix, you don't want sparks from welding anywhere near wood shavings," he said.
One of a network of about 100 men's sheds throughout New Zealand, aligned with MENZSHED New Zealand Inc, the Lincoln Men's Shed has been going for about five years.
Members meet twice per week, on Monday and Tuesday afternoons, to undertake their own projects and projects for the community.
Members also mentor groups of Lincoln High School students. A group of four recently competed two picnic tables. The next group of four arrived last week and are planning to make bench seats for the school.
Half of the new shed will be an extension of the current shed's workshop space, while the other half will be a meeting room, toilets and kitchen facilities.
Currently members take along thermos' and coffee cups, and use the neighbouring rugby club's outdoor toilet.
"We have got enough building skills in our ranks that we can do the internal building work, and lining, ourselves."
