Sports and entertainment giant Anschutz Entertainment Group has offered new details on a $500-million expansion of the J.W. Marriott hotel complex at L.A. Live to the Downtown Los Angeles Neighborhood Council’s Planning and Land Use Committee, just one month after filing plans with the city.

Urbanize L.A. reported Tuesday that the proposed development, being designed by downtown L.A. architecture firm Gensler, calls for the construction of a 38-story hotel tower at Olympic Boulevard and Georgia Street.

The proposal arrives as the city pursues adding new hotel stock within walking distance of the Los Angeles Convention Center, which has struggled for years to compete with regional rivals due to a shortage of exhibition space and guest rooms.

With the expansion, scheduled to break ground in early 2017, the J.W. Marriott hotel would feature a total of 1,756 guest rooms and 270,000 square feet of conference space when completed. The new 755-room tower will also feature approximately 17,800 square feet of street-fronting retail space, as well as a fitness center, rooftop pool, amenity deck and several food-and-beverage venues.

The second component of the project calls for the construction of two floors atop the nearby Olympic West Parking Garage, adding 170,000 square feet of meeting, exhibition and event space for the hotel.
