The house comprises two volumes that flank an interior sunken courtyard, creating a dynamic sequencing of exterior and interior spaces that is highly atypical in urban Dublin. A contemporary glass bridge is suspended across the central void. This staggering of two masses best resolves the challenge of highlighting the preserved wall. Overlooking the interstitial courtyard, the historic façade is reflected across the contemporary glazed forms that surround it. As part of the Dublin Green Building Pilot Program, the Flynn Mews House utilizes a significant amount of sustainable measures achieved through a holistic design approach: recycled and high performance materials, solar panels for domestic water heating, and radiant floors heated by an underground pump system that incorporates gray water.
