Located in neighboring historic townhouses on Manhattan’s Upper East Side, Diller-Quaile enrolls approximately 1,200 music students ranging in age from pre-school to adult.  MBB conducted a planning study to analyze the current facility and programming needs. We generated multiple strategies for reconfiguration and strategic expansion of the narrow townhouses to address the growing Instrument and Vocal program. Our focus was on creating spaces  that would comfortably accommodate music education on a range of scales, from individual instruction to group practice to large performances encompassing the diverse Diller-Quaile community.
