BOULDER — An official groundbreaking was held Tuesday morning for a pair of hotels that will have 375 rooms between them and an office building that is being constructed at the northwest corner of 28th Street and Canyon Boulevard in Boulder.

Denver-based NAI Shames Makovsky is partnering with Boulder developer Lou DellaCava’s LJD Enterprises on redevelopment of the site of the former Golden Buff hotel and the former Eads Newsstand.

In addition to Shames Makovsky building a 203-room Embassy Suites and a 172-room Hilton Garden Inn, DellaCava is building a 42,000-square-foot office building there.

The property has already been cleared by Milender White Construction Co., and the hotels are expected to open in 2017.

“This project has been uniquely designed and programmed to both meet the extensive requirements of the city of Boulder, while incorporating locally infused interior design elements that celebrate the unique aspects of the community,” said Walter Isenberg, president and chief executive of Sage Hospitality, a partner in the project.

The two-block site will feature the two five-story hotel buildings along with Della Cava’s four-story office building. The hotels will share a pool and back-of-the-house space. Underground parking will also be shared with two stories of valet and self-parking for the hotels and dedicated spaces for the office complex.
