firm profile


Danita Rooyakkers, Michael Carroll and Attila Tolnai formed their design and build company in 1995 and subsequently have produced a series of urban infills for Montreal’s inner city neighbourhood. All the projects are built on the speculation that it fits an emerging market for alternative development in the North American city in which innovative design is matched with an economy of building. The projects are experiments that seek a balance to this dynamic equation.


The projects Thin House and Twin Tower House attempt to address the historical context of their neighborhoods within a contemporary sensibility. The outcome is an industrial aesthetic matched with a domestic scale of building in which the pragmatic dictates of urban planning by-laws are interpreted with an innovative eye. The projects are mutations of a loft in the industrial landscape that become a thin vertical loft of minimum width enclosed within a prescribed building envelop. The result is a series of urban infiltrations that make an argument for a leaner, more urbane architecture for city life.
