Demolition continues inside the Trilogy Health Services building downtown as crews work to repurpose the former hospital building into a four-floor senior living facility.

Demolition work on the top two floors of the old King's Daughters' Hospital building has been completed, Trilogy Health Services spokeswoman Leslie Knox said.

Crews now are removing walls and interior portions on the lower levels of the facility, she said.

As crews clear out the old, Trilogy officials and contractors begin thinking of the new. So far, officials have determined what services and the number of rooms that will be located on each floor, Knox said.

The first floor will include 15 private short-term rehabilitation suites for post-surgical therapy.

The second floor will be a skilled-nursing floor with 18 private suites and eight semi-private or companion suites. The skilled-nursing floor will provide longer-term medical care.

The third floor will feature 26 assisted-living apartments, with three semi-private apartments.

Independent-living spaces will be on the fourth floor, with nine one-bedroom apartments and six two-bedroom apartments.

Exact floor plans are still in the works, Knox said, and will be unveiled at a later date.

Initial plans for the facility - unveiled during a joint press conference with KDH officials in January 2013 - included the possibility for future healthcare-related retail spaces in the facility.

Trilogy President and CEO Randy Bufford said at the time the new facility would bring about 120 new full-time jobs to Madison.

Trilogy Health Services took control of the former King's Daughters' Health property on April 1, 2013, after purchasing several pieces of the downtown hospital campus for $1.

Trilogy hopes to open the facility by the end of this year.
