Play Harder Designs

smart, artful interiors for real life

About PHD

Work Hard, Play Harder

A former attorney with a master's degree in Art History, including advanced coursework in architectural and design theory, Mary Rosewater established Play Harder Designs, LLC in 2017. Having spent the nearly two decades prior extensively renovating a series of older homes in Westchester and Dutchess Counties, NY, Mary - a mom of two active boys; two huge, fluffy rescue dogs; and a cat - developed, possibly by necessity, a unique approach to interior decorating.  As an art historian, she values well-composed, beautiful and artful spaces in which color, texture, shape, and composition hold sway over any orthodox design style.  At the same time, she believes that even the most beautiful spaces cannot truly be successful unless they are also highly functional, comfortable, durable, and family- and pet- friendly when desired. Simply put, Mary's goal with PHD is to imagine, plan, and then deliver smart, artful interiors for real life!
