Based in London, the practice’s portfolio of civic atriums and public presentation spaces is characterized by heavy structural concrete, intricate waffle-grid ceilings, and precise daylighting drawn deep into interiors through flush roof apertures. This work serves as a strong reference when detailing high-volume gathering environments, particularly when integrating industrial steel frames with softened planting edges or specifying rippled reflective surfaces to capture dynamic light and movement.

Interior concrete atrium with grand staircase and arched clerestory windows.

A monumental concrete atrium precedent featuring dramatic waffle-slab geometry, deep reveals, and high arched clerestory openings suitable for large civic or institutional buildings.

What we like about this project
Intricate waffle-like beam grid forming the intermediate frieze below the clerestory.

Geometry
Multi-level circular or polygonal atrium volume with deep waffle-like concrete waffle slabs and grand stair ascending through the center.
Structural guess
Cast-in-place concrete columns and deep waffle slabs framing a multi-story open volume.
Spatial scale
Monumental multi-story volume with a person visible for human scale on the stairway.
Lighting
Direct bright daylight through high arched clerestory windows casting sharp diagonal shadows.
Atmosphere
Solemn, cavernous, and bathed in dramatic shafts of daylight.
Environmental context
Large indoor public or civic atrium space.
Spatial experience
Monumental scale with layered vertical tiers; shafts of sunlight create strong contrast across the raw concrete surfaces.
Composition rhythm
Repetitive vertical structural piers paired with regular arched window bays above.
