Harry Allen's success as a furniture designer has translated into many other arenas. His achievements include interior design for several retail and restaurant projects both in the US and internationally. He also designed the offices for Metropolis Magazine and the Guggenheim Museum.

Allen's vision has translated into the world of product design. He has designed an extensive range of home furnishings, cosmetics, packaging and the Reality line of products produced for upstart design company Areaware. Areaware is a New York City based design collective. "We are dedicated to promoting local designers who take a novel yet honest approach to their work. Our products are decorative but go beyond ornament. Each has an underlying meaning which we believe can deepen the relationship people have with the everyday objects in their lives."
