Treanor

Based in Kansas City, Missouri, Treanor pairs the monumental proportions and carved stone details of civic architecture with deeply recessed shadow-box glazing and highly organized, tactile healthcare and corporate interiors. This portfolio serves as a strong reference when detailing multi-story window framing, specifying acoustic and green wall accents in wellness settings, or integrating precise functional floor zoning within specialized health and office environments.

Exterior grand facade and golden dome of the Colorado State Capitol by Treanor, viewed from a sweeping lawn and central monumental staircase.

Colorado State Capitol

A classical civic precedent featuring a monumental stone facade, central colonnade, and gilded dome, useful for studying traditional institutional scale and symmetry.

What we like about this project
The distinctive rose-toned Colorado onyx (Colorado Roseate) used within the interior is echoed by the grandeur of the exterior approach steps.

Geometry
Symmetrical neoclassical composition with a central projecting pavilion, colonnade, drum, and prominent gold-leafed dome rising above a multi-tiered horizontal base.
Facade system
Load-bearing stone masonry walls featuring punched windows, classical cornices, and engaged columns/pilasters.
Structural guess
Mass masonry bearing walls with heavy stone piers and classical structural columns supporting upper floors and dome structure.
Spatial scale
Monumental civic scale, towering multiple stories with oversized classical orders and deep entry stairs.
Lighting
Direct, clear daylight with crisp shadows highlighting the deep column porticos and neoclassical relief details.
Atmosphere
Formal, dignified, and enduring under bright daylight.
Environmental context
Set within an expansive urban park lawn surrounded by mature trees under a clear blue sky.
Spatial experience
Approached axially from a lower terraced lawn via a wide monumental stair, creating an imposing and ceremonial civic presence.
Composition rhythm
Strict bilateral symmetry with repetitive window bays flanking a central monumental portico and vertical drum.
