Tillotson Design Associates

Based in New York, Tillotson Design Associates creates light-driven spatial environments across cultural lobbies and performing arts centers, defined by glowing facade apertures, concealed luminaire troughs, and high-density technical gantry systems integrated into complex ceiling geometries. The work provides a detailed reference when specifying flush structural floor glazing over subterranean historical elements, detailing concealed perimeter lighting within nested curved ceilings, or balancing dramatic architectural illumination with industrial theatrical rigging.

Night view of a stone courtyard entrance plaza with a person standing before a lit building facade featuring vertical fins and circular porthole windows.

Princeton University Art Museum — Tillotson Design Associates

An institutional courtyard entrance precedent demonstrating dramatic night lighting, rhythmically fluted stone facade elements, and contrasting geometric window openings.

What we like about this project
Circular porthole windows are set flush into a heavy stone wainscot band, creating an unexpected play of curves against orthogonal joints.

Geometry
Symmetrical low-rise courtyard framing an entry portal with vertical fluted facade elements flanking the sides and stacked window rhythms above and below.
Facade system
Precast or cut stone panel system with articulated vertical fins, recessed tall windows, and circular portholes.
Structural guess
Steel or concrete frame with heavy stone panel curtain wall and shear elements.
Spatial scale
Human scale entry plaza framed by two- to three-story institutional building wings.
Lighting
Artificially lit at night with warm uplighting along benches, internal glow from windows, and focused downlights framing the entry path.
Atmosphere
Solemn, luminous, and controlled; quiet evening mood generated by precise architectural lighting.
Environmental context
Urban university campus courtyard at night under a dark sky.
Spatial experience
A grounded, monumental approach that compresses into a warm, softly lit entry portal under a dark night sky.
Composition rhythm
Vertical fins on left balance vertical slit and circular windows on the right, converging on a central lit portal.
