Sculpted by the angles of the sun, Solar Carve (40 Tenth Ave) explores how shaping architecture in response to solar access and other site-specific criteria can expand its potential to have a positive impact on its environment. Located at the edge of Manhattan between the High Line park and the Hudson River, the building takes its unique form from the geometric relationships between the allowable envelope and the sun’s path.

In addition to producing a faceted, gem-like facade, this integrated response allows the building to benefit the important public green space of the High Line—privileging light, fresh air, and river views for the public park—while also becoming a new iconic silhouette on the New York skyline.

The design advances Studio Gang’s “solar carving” strategy for enhancing connectivity in tall buildings. Developed through the Studio’s ongoing tall building research, solar carving involves using incident angles of the sun’s rays to sculpt a building’s form.

The glazing system has been geometrically optimized into a pattern of three-dimensional facets that articulate the carved sections of the tower. The curtain wall unit is composed of a central diamond-shaped panel tilting downward, surrounded by four triangular pieces that are perpendicular to the slab to achieve standard stack joints. The carved curtain wall not only blocks sun glare and heat gain but also creates dynamic corner workspaces. The facade will feature high-performance glass with low reflectivity.

Studio Gang Wins Four 2020 Architizer A+ Awards

Three projects designed by Studio Gang have won four 2020 Architizer A+ Awards, which recognize the best architecture, spaces, and products from across the globe.


Green Building & Design — "Studio Gang Protects Public Space While Delivering Flexible Offices in NYC"

“Studio Gang has been developing the strategy of solar carving for years as a way to enhance connectivity in tall buildings. . . . [Solar Carve] is sculpted at the angle of the sun in order to preserve solar exposure on the adjacent High Line Park.”


The Plan — "The Black Diamond"

“Her buildings have always been at the cutting edge of technology…allowing the architect to step outside the banal and use artistic imagination as a way of providing real answers to real problems.”


Solar Carve Wins Architecture Merit Award in 2020 AIANY Design Awards

“Revealing the architectural potential of a people-centered, analytical approach, Solar Carve offers a model for how an integrated approach to site-specific environmental conditions and updating inherited zoning codes can enable new buildings to improve dense neighborhoods and protect public space.”


The Urban Audubon — "Studio Gang Begets Bird-Friendly Beauty on Tenth Avenue"

“NYC Audubon welcomes this beautiful new ecology-minded structure. It may serve as an inspiring example for future bird-friendly design, as it includes many features now required in all new construction in the City, thanks to new legislation recently passed by the New York City Council.”


New York Times — Fall Architecture Preview "The New Architecture: Sky Parks, Tidal Pools and ‘Solar Carving'"

The New York Times describes the recently completed Solar Carve as “an act of architectural generosity” in their fall architecture preview.


Fast Company — "Tall Buildings are Leaving Cities in Darkness. These Architects Have a Radical Fix."

“Viewed straight-on from the Hudson River, 40 Tenth looks like a simple rectangle. Shift to the right or left, though, and the building cuts inward, creating a dramatic faceted facade. The new development is part of Gang’s exploration into “solar carving,” a marketable term the firm uses to describe its process of shaping buildings based on the sun’s location and its desired effect.”
