The Interface House re-envisions the domestic living experience in Ohio by promoting a theme of consolidation, encouraging the average person to re-consider the use of space within their home.
The house utilizes a centralized living space that
needs. It consists of two distinct interfaces, one exterior and one interior.
The exterior interface is performative, from an architectural and an energy use standpoint.
ventilation, shading, daylighting, and the modulation of light and shadow. The facade, composed of re-claimed Ohio barn siding, acts as a rain-screen and draws subtle reference to Ohio’s agriculture heritage.
Interface House is designed in response to the oversized contemporary (American) living condition. To promote consolidation, the design demonstrates a minimal footprint, both physically and ecologically; suggesting a lifestyle in which

The INTROhouse is designed for the typical post-industrial American city where the loss of manufacturing has left a ring of vacant industrial sites surrounding the downtown. Adjacent to the central business district, these sites are ideal for re-colonization by people moving back to the city. INTROhouse is designed as a catalyst for this process.
The existing post-industrial language of the site forms the basis for the house’s architectural identity. The structure is clad in rugged materials emblematic of an aging industrial infrastructure. A
garden provide the house’s occupants with views

The south elevation of the house is comprised of a double-skin system used to harness heat in the winter and ventilate it in the summer. It consists of an outer layer of factory style glazing, a 12-inch deep airspace with operable, perforated metal screens acting as heat sinks, and an inner layer of double-glazing.
The house’s photovoltaic array uses polycrystalline, bi-facial panels to produce electricity. Mounted horizontally above the house’s roof, the panels harvest ambient light for increased electrical production, while shading the roof from direct solar gain.
A portion of the photovoltaic array uses combined photovoltaic-solar thermal panels, which preheat the house’s domestic hot water supply.

The INTROhouse’s conceptual design was part of a competitive proposal process required to gain acceptance in to the 2011 Solar Decathlon Competition.
The house’s winning design boards and physical model were featured at the National Building Museum in Washington, D.C. as part of:

a pronounced cantilever that ‘projects’ over a recessed exterior garden. This physical projection creates a theater wherein the house’s inhabitants can have a privileged view of their surroundings.

The south side (street side) of the house becomes activated by the actions of the occupants inside. The resulting visual effects are displayed on the translucent glazing facing Oakland Avenue. Silhouette, light and shadow, and subtle differentiations in color and luminosity are all displayed to the street and the neighborhood beyond.

The transformative nature of the street facade creates many cinematic effects representative of the tempo of its inhabitants’ activities. This is the most public form of projection as the street facade becomes a virtual screen for viewing.
The ‘aspect ratio’ of the glazing is 2.20:1, an

Sectional variation is a strong theme throughout the house’s interior and exterior. The front facade
is little activity inside. Although, once dusk approaches, interior depth and complexity begin to register to the exterior.
The street facade represents projection in its phenomenological form. Literal, photographical projection occurs when images are projected on to

The projected images create a glow that emanates from the recessed garden at night.

facade towards the cantilevered space projecting over the garden. This is a transitional space where the user sheds the role of the performer as he walks away from the street. Once in the projected space, he gains a private, privileged view of the garden space below.
The garden walls form a new horizon line, and contain a quiet, contemplative space that frames the main house. Here, inhabitants witness the physical projection of the house as it seemingly extends towards them.
