This startup incubator has one of the most gorgeous offices we've ever seen

For years, Brooklyn Navy Yard sat underutilized, a massive piece of real estate on the Brooklyn waterfront filled with the relics of World War II.

But now, Washington, D.C.-based startup incubator 1776 is doing its part to revive the historic space.

1776 is setting up shop in the navy yard as the anchor tenant, opening the doors of a "beta" space as it continues work on its 32,000-square-foot campus nearby. The company is rehabbing part of a massive building that used to house munitions during World War II with plans to move into that space - called building 77 - in the first few months of 2017.

1776 is two things at once: a startup incubator with a focus on companies in highly-regulated spaces like healthcare, transportation, and education, and a seed-stage investor with 22 investments under its belt.

Business Insider got a tour of both the beta space, which officially opens Thursday evening, and building 77, which is still under construction. Check it out.
