Hearts have applied for planning permission to build their new main stand at Tynecastle.
The stand will boast seating for 7000 fans, bringing the stadium’s total capacity up to more than 20,000.
Club bosses believe that the state-of-theart extension could open early in the 2017-18 season.
Hearts also said that planning permission had been granted for new facilities in the “undercroft” of the Wheatfield Stand.
Work to construct new facilities for the temporary club shop, ticket centre, admin offices and dressing rooms is now under way.
A Hearts statement read: “The club has entered into the next stage of the Tynecastle redevelopment by formally submitting the planning application for the new main stand at Tynecastle to the city council planning department.
“This follows on from the public consultation process that has been carried out in recent months.”
