identify the Federal Building as International Style architecture. Pioneered by European architects shortly after World War I, the International Style rejected the ornate designs of previous eras, turning instead to a streamlined, modern approach for buildings. Walls were flat planes with no decorative treatment and windows were placed flush to the exterior. This style became widely accepted in the United States in the mid-1930s. The building also represents a regional construction type and style known within Federal organizations as New Deal Concrete. A number of federal buildings built under Roosevelt's New Deal plan exhibit similar characteristics. The Federal Building is located at the southwest corner of Mission and Stedman Streets in downtown Ketchikan. The site is bounded by concrete sidewalks and grassy lawns on the northwest and northeast sides, and by paved concrete parking lots on the southeast and southwest. The northwest lawn features a metal flagpole with a concrete base, one of two originals. After almost four decades of grass bounded by chain link fencing, in the mid 1970s, landscaping was added and the fencing removed at the northeast and northwest lawns at Stedman and Mission Streets. The original steps at the main entry have been altered by the addition of a functional but insensitively designed off-center ramp with painted free-standing metal handrails. The L-shaped building consists of a long and narrow six-story tower stretching along Stedman Street to the northeast, with the narrow end of the tower and a one-story wing facing Mission Street to the northwest. The inside of the "L" originally included a basement level boiler room. While the main blocks of the building have remained intact; in 1954, a one- and two-story wing was added to the southeast side, east end of the main tower, adjacent to the boiler room. This addition has metal panel and stucco exterior finishes. The original building sits on a slightly projecting concrete base. The concrete wall surfaces have a rubbed finish and are smooth except for continuous horizontal reveals at the heights of window sills and heads on each floor level. The building is terminated by a slightly recessed continuous concrete parapet cap. The exterior elevations are penetrated by grouped window openings which align vertically and horizontally, from floor-to-floor. The original horizontal-light, two-over-two, wood double-hung sash windows, some with matching transoms, have been replaced by new, single-light, one-over-one, wood units with operable awning sash below fixed upper sash(es).
