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.

Mass timber terraced pyramid building proposal by 3XN Architects overlooking a harbor and waterfront promenade.

201 E Pratt St.

A mass timber terraced pyramid precedent by 3XN Architects, illustrating how large-scale commercial or mixed-use massing can step down to integrate public green roofs and waterfront connectivity.

What we like about this project
An expansive terraced public staircase and planted landscape cuts directly up the side of the building volume.

Geometry
A stepped triangular massing profile cascades down toward a waterfront plaza, integrating multiple habitable terraced levels and landscaped green roofs.
Facade system
Exposed mass timber post-and-beam structure with floor-to-ceiling glass and continuous balcony shading.
Structural guess
Exposed mass timber glulam post-and-beam framing with CLT floor slabs.
Spatial scale
Large multi-story urban development with human-scaled retail ground floor and accessible terrace paths.
Lighting
Bright direct daylight casting soft shadows across the deep recessed balconies and sloped green landscape.
Atmosphere
Vibrant, open, and community-oriented, blending civic landscape with architectural timber framing.
Environmental context
Dense urban waterfront setting adjacent to high-rise towers, a marina, and a historic ship berthed at the quay.
Spatial experience
The building opens outward to the water, drawing public circulation up along exterior landscaped terraces and framing views across the harbor.
Composition rhythm
Horizontal timber structural grids alternate with deep recessed terraces and vertical planters.
