Chelsea Brownstone with Original Features Coliving Open to Outsite Members and Guests Make yourself at home in Chelsea. This 20 room classic brownstone has a rooftop sundeck as well as a ground floor garden - ideal for summer evenings with other Outsite Members. The original features, including tiled floors and an elongated wooden banister, have been maintained to retain the charm of this 1848's build. It's now fully renovated with a designated workspace, lounge and kitchen. This home has played a unique part in Chelsea's history, being one of the first homes for the GMHC in the early eighties.
