Mid-Century Modern (MCM) architecture is a further development of principles of organic architecture combined with many elements reflected in the International and Bauhaus movements – including the work of Gropius, Le Corbusier, and Mies van der Rohe. Mid-Century Modern architecture is characterized by clean simplicity and integration with nature. The MCM style at The Bay Roc emphasizes creating structures with large windows and open floor-plans with the intention of opening up interior spaces and bringing the outdoors in. Mid-century buildings, including The Bay Roc, utilized then-groundbreaking post and beam architectural design that eliminated bulky support walls in favor of walls seemingly made of glass. The Bay Roc incorporates many MCM vintage features such as stained glass curtain wall dividers, wood-formed concrete walls, large sliding windows, and large open arching beams. Even the font used for The Bay Roc original sign is a derivation of Gil Sans, a Mid-Century Modern typeface.
The Bay Roc is an outstanding and rare example of residential Mid-Century Modern architecture applied to an apartment building within the Portland Metropolitan area.
