A 37-year-old office building in the Golden Triangle is coming down.
Crews began demolishing the five-story structure at 990 Bannock St. in recent days.
The property is owned by apartment developer Lennar Multifamily Communities, which paid $18.5 million last year for it and much of the parking lot to the east — 2.1 acres in all.
Lennar submitted a site-development plan to the city last year, proposing a 17-story, 389-unit complex on the existing parking lot, at 921 and 951 Acoma St.
Lennar has yet to submit a site-development plan for the 990 Bannock parcel, where the demolition is occurring, but an early-stage proposal submitted to the city indicates it wants to build a second large apartment complex on that site.
The 110,000-square-foot 990 Bannock building was constructed in 1982, according to city records. The building was owned by Denver Health from 2002 to 2015.
