Developer Tony Clear said work was under way at the two buildings on the old Roslyn Woollen Mill site and several future tenants had been confirmed.
A 24-hour gym, offices for an insurance firm and premises for a training organisation would all be accommodated in the renovated building at the intersection of Kaikorai Valley Rd and Stone St.
As was the case for all businesses in the industry, the construction project had been affected by supply shortages, but workarounds had been found and he was optimistic the work would be finished in October.
About $3.5 million was being spent on the project, he said.
"I’ve done a few of these before in my time, but they’re always exciting when they’re happening," Mr Clear said.
In mid-2020, the Otago Daily Times reported approval had been granted by the Dunedin City Council to a proposal to redevelop the former wool mill.
Three bays at the north end of the building would be demolished and a new structure would be built including a cafe, trade-related retail and industrial uses.
More windows would be added and repainting would occur, along with earthworks to improve car parking.
