3XN Architects

Based in Copenhagen, 3XN Architects crafts dynamic civic and commercial forms marked by flaring, sculpted upper envelopes suspended above transparent ground floors, where expressive fin arrays and integrated landscape staircases draw public movement seamlessly onto accessible green roofs. This body of work serves as a precise reference when detailing continuous public pathways that climb building facades or specifying vertical fin geometries that transition into entrance canopies across large-scale cultural and arena facilities.

Rendering by 3XN Architects of a terraced timber and glass building with a stepped green roof beside a waterfront boardwalk.

201 E Pratt St.

A waterfront architectural precedent showcasing terraced green roofs and heavy timber framing that integrates public open space directly with the building envelope.

What we like about this project
The building form dips down to meet the ground plane at one corner, creating a continuous accessible walkway onto the roof.

Geometry
An asymmetrical wedge-like massing with sweeping terraced floor plates that step upward to a central peak, flanked by waterfront promenades and timber boardwalks.
Facade system
Glazed curtain wall inset within an expressed timber post-and-beam structural grid.
Structural guess
Mass timber framing with integrated post-and-beam structural grid and cantilevered floor plates.
Spatial scale
Large public-scale development with multi-story terraced elevations, framed by pedestrian figures on expansive timber and stone decking.
Lighting
Bright midday sun casting crisp shadows from figures and projecting structural elements under a clear blue sky.
Atmosphere
Open, vibrant public atmosphere blending active waterfront recreation with sustainable building form.
Environmental context
Urban waterfront setting adjacent to a harbor, framed by existing high-rise commercial towers and a historic ship moored nearby.
Spatial experience
The eye is drawn from the foreground timber deck across the water up the stepped green terraces, dissolving the boundary between urban landscape and architectural mass.
Composition rhythm
Horizontal bands of terraced planting rhythmically repeat up the sweeping incline of the building mass.
