As the head of interior design at Kevin Roche's firm
Roche-Dinkeloo, Platner created office spaces that were flexible, understated and efficient. He chose a rich, quiet colour scheme to create a warm environment and installed custom-made furniture designed to eliminate needless effort. Ergonomic desks included built-in telephones and special compartments for files and office machines. Platner was a believer that a building's design should come from within: "I try to conceive of what would be the best atmosphere, the best character [for a particular building]." After gaining experience working with several contemporary designers, Platner established his own firm, Warren Platner Associates, in Connecticut in 1965, Platner's firm was composed purely of fully qualified architects, who he believed could manage any design task, whether it was interior planning or the architecture of a skyscraper: "Architects can do any design task, if they wish to do so." One of Platner's first solo projects was the New York showroom for
Georg Jensen, the high-end seller of
Scandinavian furniture and lighting, called the
Georg Jensen Design Centre. It opened in 1968. Platner's design for
Windows on the World, a restaurant atop the original
One World Trade Center, which originally opened in 1976, is well known. Mimicking the interior of a grand ocean liner, the main dining room was elaborately terraced to provide views for every table, intimate seating and a sense of drama. Paul Goldberger, architecture critic of
The New York Times at the time, described the restaurant's lush interior, with its soft pastels, fabric-covered walls and what seemed like miles of brass railings, as an example of "sensuous modernism". Platner, who also created lighting fixtures, floor and window coverings, furniture and architectural ornaments for clients, completed many other noteworthy projects, including the interior design of
Water Tower Place, the vertical shopping mall that opened in
Chicago in 1976, and the 1986 renovation of the
Pan Am Building lobby for its new owner,
MetLife. Warren Platner was inducted into
Interior Design magazine's hall of fame in 1985. ==Personal life and death==
