Spring has arrived, and at MAG Partners, we’re all about creating spaces where people can soak up the sunshine and connect with nature.☀️🌿 Our outdoor spaces are designed to make our residents feel their best - from vibrant rooftops and lively courtyards at Ruby in Chelsea , to walking paths and wide open spaces with waterfront vistas at Baltimore Peninsula.

At MAG Partners, we know the ground floor is more than just retail—it’s the heartbeat of a building. 🏙️ We carefully curate tenants that bring value to the community, creating spaces that serve, connect, and uplift the people who live there.

Forbes recently spotlighted the growing trend of urban work campuses. With increasing numbers of people returning to the office, work campuses like Baltimore Peninsula, developed by MAG Partners LP, are taking work-life to the next level. Offering abundant green space and 1.2 million square feet of residential, hotel, and office space across five buildings, Baltimore Peninsula is a waterfront community where top restaurants and major employers like Under Armour and CFG Bank can thrive. Attracted by restaurants, amenities and year-round events like concerts, outdoor movies, and free yoga classes, many of those employed at Baltimore Peninsula have chosen to live right within the community – redefining what it means to work and live in the same space. 🏙️

MaryAnne Gilmartin’s favorite view is on the roof of 335 Eighth Avenue, where she can look back at Ruby, our company’s debut project. When 335 Eighth Avenue starts leasing this summer, MAG Partners will have brought to market nearly 600 units of mixed-income housing to the West Chelsea neighborhood. Sitting one block apart, we think of these two buildings as sisters, both designed by COOKFOX Architects and constructed by Urban Atelier Group with textured hand-laid brick facades that reflect the historic character of this corner of Manhattan.
