ST. PAUL, Minn. (AP) -

Minnesota officials are soliciting bids for proposed upgrades at the Governor's Residence in St. Paul, including a renovation of the property's carriage house and a new pavilion for events.

Materials posted by the Department of Administration say the estimated $800,000 in work would be paid for through private donations and proceed only if that money is secured.

The plan calls for the carriage house's remodel and construction of a 4,000-square foot addition that will include a commercial kitchen, dining area, conference room and some office space.

Department spokesman Curt Yoakum says the Governor's Residence Council recommended the project after interviewing former first ladies and staffers as well as learning how other states use their governors' residences.

Minnesota Public Radio reports construction may not begin until the spring of 2018.
