The award-winning eleven-story facility provides a healing environment designed to support young patients and their families while enhancing communication and staff productivity. The addition laterally expands the functions of the Berthiaume Family Building, unifying new and existing facilities so they function with minimal separation. The addition includes two family-centered intensive care units: a cardiac ICU and medical surgical ICU.

Unique factors in the design process included building on a tight urban site in the congested Longwood Medical and Academic Area that required the relocation of underground utilities and a street.
