Hamilton Development is a single family residence in the Leslieville district of Toronto. The 2,035 gross square foot dwelling rises 37 feet with access to a planted roof with unobstructed views of the downtown Toronto skyline. Through the Committee of Adjustment, we secured permission to site the 13 foot 4 inch wide by 35 foot 4 inch long house at the rear of the 90 foot long lot offering an elongated landscaped entry from Hamilton Street. To the rear of the lot, access is by public lane where a carport carves out a portion of the ground floor resulting in a 12 foot cantilever of the upper stories. From the entries at the street and the lane, one enters into the ground floor home office zone. A cantilevered stair dances left and right as it ascends through all floors to an operable roof skylight. A full floor room on the second floor completes the cruciform axes of the public zone. This room contains the kitchen, dining and living room areas. The third floor accommodates two bedrooms and a shared bathroom. The fourth floor houses the master bedroom suite. Full height, full wall glazing fronts the living room and three bedrooms. West exposures feature a downtown skyline view while east exposures are obscured by the birch forest of the front yard. Glazing is fully operable for ventilation and features controllable horizontal louvres on the west exposures and vertical louvres on the east. These energy conscious devices are supplemented by side wall ventilation heat exchangers and a sealed and insulated envelope which considerably exceeds all energy code requirements. The black rendered tower is set in a landscape of crushed black granite accented by the white trucks of the small birch tree forest and a planted roof of tall grass.
