ARCHITECTS LISE DE Vito and Jim Zack played all the key roles in this urban infill project. Not only did they design the duplex, the husband and wife team also acted as contractor and client, keeping half the space for their own use.
The challenge the couple set for themselves was to design an obviously modern building that would still blend in with the Victorian character of the neighborhood. To achieve that goal, they maintained the same scale, massing, and materials as the surrounding homes but repurposed the ingredients in a more contemporary manner.
The most dramatic feature of the project is a central stair fabricated from steel plate and acrylic. A party wall, angled from front to back, creates further interest by dividing the building envelope into two trapezoidal spaces, each with one end wide and the other narrow. This configuration gives each unit equal access to the natural amenities of light, air, and views.
