Architectural Sketch: Interior Staircase

This pen sketch depicts an elegant residential interior, likely a study for the staircase design at Mossley Hall. The drawing showcases the hallmarks of Gilded Age domestic architecture: ornamental railings, coffered ceiling details, and carefully proportioned spaces. Artist Arnold William Brunner was an influential American architect known for designing substantial homes and public buildings in the late nineteenth century. This working sketch reveals the architect's design process—rapid linework establishing spatial relationships and architectural vocabulary before final execution. The composition emphasizes vertical circulation and light, with atmospheric cross-hatching suggesting depth and shadow. Such preliminary drawings served as blueprints for craftsmen and as records of the architect's vision.
