Once building is finished at the Master Home Improvement site in January, there will then be a 10-week fit-out, according to developer Satterley Property Group.
Chief executive Nigel Satterley said the Brighton district centre looked like a busy construction site with several major projects starting.
Satterley has sold more than 17ha of commercial land, including the Masters store, a Woolworths supermarket and a Big W.
The 13,500sqm hardware store is at the corner of Marmion Avenue and Butler Boulevard, and includes specialty retail stores.
There will also be several large stores in the district centre, 40 speciality stores, a child care centre, a tavern and 900 parking bays.
