Macro Sea is a real-estate developer based in New York City. We design, build, and operate projects for people and places that we care about.

Created in 2009, Macro Sea has executed projects in the built environment and conceptual realms, in New York City and around the world. As part of our core mission, Macro Sea conceptualizes and builds creative interim use projects that transform and energize our surroundings. Our design projects have been featured in MoMA and the Venice Biennale.

With the successful completion of the G.27 Global Institute in Berlin and the launch of New Lab in the Brooklyn Navy Yard, we seek to push the boundaries of user experience, material culture, and social environments with our Other Spaces platform, which will debut in Williamsburg, Brooklyn in 2019.




Macro Sea exists as a series of ongoing collaborations between experts in a wide variety of disciplines including artists, architects, designers, lawyers and others. The company has served as the entrepreneurial framework for most of David Belt’s development pursuits since 2009.

Collaborators include Jocko Weyland (2009-2011), Alix Feinkind (2009-2012), Elise DeChard (2011-2013), Alexandra Escamilla (2012-2014), Rebecca Birmingham (2010–2018), Nicko Elliott (2013–2018), Liz Song (2015–2018), Stephanie Hemshrot (2014–2018), and Allison Moss (2016-2018).
