Here’s a follow-up blog with additional details about Shea Properties’ big plans for Block 109. Please keep in mind that all of this information is preliminary and that the building’s program and design are still being finalized.

The project’s mixed-use development program is best explained by this massing diagram:

Underground, are two basement levels containing approximately 80 parking spaces plus various mechanical and other building functions. The ground floor includes a mix of retail and office/hotel/residential lobby uses. Levels 2 – 7 (gray) are above-grade parking totaling approximately 620 spaces. On the 17th Street side, the next two levels (yellow) represent a 2-floor fitness center and, above that, are 15 floors (green) of offices totalling over 300,000 SF of space.

On the 18th Street side, above the parking are 11 floors (gold) that feature approximately 220 hotel rooms. Above the hotel uses are 13 floors (red) of residential condominium units, topped off by a mechanical penthouse.

In total, the 17th Street tower will be 24 floors plus the crown, and the 18th Street tower will be 31 floors. Both towers top off at approximately 390 feet. Again, these numbers are preliminary and subject to change.

The project architect is Davis Partnership Architects.

That’s about it for now. More information about 999 17th Street will be posted when available!
