The Tandem is a 5-storey residential building located in the very animated St-Jean Faubourg nearby the Old-Quebec area. The project rises on the site of a former open air car park, considered as a scratch in the urban fabric of the area. This site has been the subject of many debates over the years.
It’s in this context that the project takes its place in the community, as the result of a long dialogue between the developer, residents, architects, urban planners and the city officials. The Tandem is intended as an example of good architectural and urban practices and participates in an aesthetic gesture that perfectly suits the spirit of the place.
The façade shows a vertical pattern with reliefs to minimize the massive effect of the construction and to perfectly integrate the style of the surrounding houses setting the rhythm of the streets. The materials are also a response to distinctive architectural elements used on the existing houses and buildings around.
Saint-Jean Faubourg is a beautiful area mixing commercial and residential functions with a typical architecture of the late 19th century: Wood or brick houses, canadian-style sheet cover roofs or flat-roof houses, oriel windows, portes cocheres, etc. The Tandem responds to those distinctive elements with the brick used at the base of the construction and in the treatment of the town houses. The highest part of the building is designed in a light-weight and flexible fashion with glass and metallic covers. The treatment of the interior of the balconies is a reminder of the oriel windows seen on several houses in the area.
With the intention to connect the new construction with the built environment, the Tandem is conceived as an « O-shaped » plot, very commun in the neighbourhood. The central outdoor space is a generous green courtyard visible from the street. On Saint-Jean Street, the height of the building is adapted to the urban frame with its 4-storey volume offering commercial spaces on the ground level.
The Tandem offers eleven 2-storey townhouses overlooking the Richelieu Street. On the upper levels, every unit benefits from a flow through effect thanks to the inner courtyard in the center of the project. An ingenious system of exterior gateways also allows each apartment to have its own private entrance. Since a wide surface on the ground is devoted to circulations, a vertical garden stands as a privacy screen and contributes to the natural cooling of the building. A community hall and a rooftop terrace provide the residents a fabulous view over the city. The project also includes an underground parking for 107 cars.
On Saint-Jean Street, the ground floor offers local shops and facilities to serve the community and to provide the necessary activity to create a great neighbourhood spirit.
Sustainable design
While developing the Tandem project, architects included a lot of elements to meet the current requirements of sustainable development and densification. By example, the vegetation on the courtyard, the choice and the positioning of the doors and windows as well as the white roof will reduce the heat island effect and the ecological footprint of the project. The Tandem also proposes a vertical garden as a privacy screen, which contributes to the natural cooling of the whole building. The East façade integrates a vegetal wall to ensure continuity with the courtyard.
The orientation of the building has been a determinant factor in the architectural choices. The interior courtyard was designed accordingly with the sun’s path to optimize the natural lightning inside the apartments. Its disposition allows to lower the energy consumption related to artificial lighting and mechanical cooling, since 85% of the units are opened on both sides, offering a well ventilated living space.
Sustainable mobility is also encouraged with a bus stop located just in front of the building.
The Tandem consolidates residential use with the commercial fabric of St-Jean Street and incorporates several elements of sustainable development while encouraging urban densification efforts. The project also meets design criteria promoting the modulation of the volume, the treatment of voids and solids, spikes and setbacks, as well as many other refined details.
