The new owner of the Manchester Grand Hyatt, San Diego’s largest hotel, is planning an extensive renovation of the 1,625-room property.

A Sept. 9 statement from Maryland-based Host Hotels & Resorts Inc., which acquired the property in March through a subsidiary for $570 million, did not disclose a financial figure for the renovation but said it would involve guest rooms, meeting facilities, lounges, restaurants and public space.

A designer is currently being selected, with work tentatively scheduled to begin in spring 2012, the statement said. A hotel spokesman said no additional details were being released at this time.

The downtown waterfront hotel was built by a local group led by developer Douglas Manchester. The original tower opened in 1992, and a second tower opened in 2003.
