Annum Architects (formerly Ann Beha Architects)

Based in Boston, Annum Architects crafts museum, cultural, and community institutions characterized by fine-grained tectonic contrasts, pairing delicate timber and steel framing with heavy masonry bases beneath sweeping, daylight-filled roof structures. The portfolio serves as a precise reference when detailing slender canopy connections against historic stone substrates or integrating overhead skylights into dense structural steel trusses for exhibition pavilions.

The State Museum of Pennsylvania

An exterior civic precedent combining a vertical stone tower with a large circular volume, useful for museum and cultural campus architecture studies.

What we like about this project
The slender high-level window band near the top of the vertical tower gives a tower-like landmark quality.

Geometry
Composition pairs a tall, slender vertical slab tower with a prominent circular drum mass set back behind mature street trees.
Facade system
Precast or stone-clad solid wall with minimal punched window openings.
Structural guess
Steel frame or concrete core construction with heavy stone cladding panels.
Spatial scale
Large civic scale; the tower rises multiple stories with small punched windows near the top.
Lighting
Bright midday daylight casting clear, crisp shadows from the tower and trees onto the building base and sidewalk.
Atmosphere
Calm, institutional solemnity under clear blue skies.
Environmental context
Urban street edge with a sloped multilane roadway, manicured lawn, and dense mature deciduous trees.
Spatial experience
From across the sloping roadway, the heavy masonry volumes establish a commanding civic presence softened by foreground landscaping.
Composition rhythm
Asymmetrical balance between the vertical rectangular tower and the sweeping curve of the circular drum.
