The 13-week project, which began in September, was part of a series of kingdom hall upgrades across the country and was one of 10 this year.
Construction manager Ben Meares said they had a core team of about 15, all of the Jehovah’s Witness faith, who were travelling around doing up the halls.
Beyond that, he said 150-200 unpaid volunteers from Mosgiel to Invercargill were donating their time to the southern builds.
It was fulfilling to give back to the community and the volunteers were enjoying being able to help he said.
"Jehovah’s Witnesses are very aware of and quite happy to be able to assist the community," he said.
The once plastered building on the corner of Railway Esplanade and Hamilton St had a "patchwork" of renovations over the years and was starting to get a bit old.
It has been re-clad, with weatherboards and bricks, has a new, lined roof and they have reconfigured the walls and layout to make it "nicer" for the locals.
In the new model there was an accessible bathroom and another multi-use room with a kitchenette and breastfeeding area.
Also being built was a separate room with a large view window to overlook the main programme and stage area, which would feature a podium and two monitors.
The plan with all these upgrades was to make them more comfortable, with fresh air-flow to create a distraction-free learning environment, Mr Meares said.
A bunch of volunteers were finishing the bricklaying on the Railway Esplanade side and one jokingly reminded The Ensign he was not getting paid.
"It’s for spiritual riches," volunteer Mosa Taliauli said.
"I just have to ring up my bank account in heaven."
There were 150 halls in the New Zealand and South Pacific region the construction team serviced.
The about 40 Gore congregation would be able to access the hall hopefully by December, once the council was done with the paperwork, Mr Meares said.
