Washington’s largest hotel is officially under construction. The mammoth trophy hotel adjacent to the convention center will have almost 1, 200 guest rooms and is set to open in 2014.

The new hotel, at 9th and Massachusetts Avenue.

It’s hard to get a sense of the details based on the renderings available, but a few things stand out. The facade appears to be broken up into a number of sections, helping mitigate the building’s great mass. Also, preservation of the historic structure on the corner is a welcome respite from the otherwise endless walls of glass. On the other hand, there are going to be huge chunks of boring pretty much all over. For the most part, it looks like exactly what you’d expect a convention center hotel to look like: Sleek, corporate, and generic.
