Located within a gritty downtown neighbourhood, this project combines the ancient Roman planning strategy of a central atrium with a tectonic strategy of subtraction and addition to transform the top floor of a nineteenth century warehouse into an urbane roof top villa. Inspired by an earlier experimental condominium prototype called Lightspace, this project employs integrated strategies to achieve effective daylighting, passive solar harvesting and natural ventilation. It similarly achieves plan adaptability by utilizing ganged storage units to define rooms and a raised floor system to contain piped services within the unit, where they can be accessible.
A central cut into the large 4,000 square foot floor introduces day light into the centre of the building and restructures the plan, section and experiential quality of the space. The southerly portion of the cut is glazed to contain a private landscaped courtyard. Like the ancient “fluvium” it contains a water feature and provides a place for outdoor use, as well as view from interior spaces. A two storey glazed “pavilion” inserted into the cut, facing south to the courtyard, has an ample roof overhang calibrated to shade the glass in summer and allow warming winter sun deep into the living areas in winter. A smaller drywall pavilion within contains the entry stair, elevator, kitchen, pantry, powder room and fireplace on the main living level and a loft area with bathroom and fireplace for guests on the floor above. It also provides access to a roof top terrace and green roof that is currently being designed for a second phase of construction. A second smaller courtyard cut in the northwest corner of the building provides a balcony to the street, as well as a smaller landscape terrace into which the dining area can be extended via a large sliding door.
