This proposal for sustainable infill housing was the
only entry from outside the host country of Canada to receive an award in this
international competition for ideas to implement the city of Vancouver's Eco-Density
CharterA Greener,
Denser City Pattern:Balancing built form and landscape, three residences
increase the allowable density of this secondary residential lot by 50%, while
maintaining 60% of the site as usable open space. Dwellings enclose a south
facing common courtyard and private terraces while maintaining the predominate
setbacks and scale of the neighborhood. With utility areas relegated to the
rear service lane a pedestrian friendly façade and garden place eyes and ears
to the street. Provisions for bicycles, recycling, water management, urban food
production and renewable energy systems foster a greener lifestyle. Repeated
along the block this forms an urban pattern of sustainable courtyard housing.
Greener,
More Affordable Housing Types:
Modestly
sized, simple dwellings, with reduced land costs greater densities provides,
require fewer resources to produce and are therefore more affordable and
greener by design. The application of shovel ready, environmentally
preferable construction technologies and materials such as vegetated roofs,
material efficient framing of composite members, renewable based insulation,
recycled fiber-cement rain screen cladding, certified/renewable hardwoods and
low VOC finishes reduce carbon and resource footprints. Energy and water
efficiencies, passive solar heating /cooling, day-lighting, an edible
landscape, access to transit and renewable energy generation in the form of
photo-voltaics contribute to sustainability and more affordable long term
operating costs.
Greener,
More Livable Open Spaces:
A
hierarchy of open spaces provides for a variety of activities while
contributing to sustainability. The entry yard within the prevailing setback
forms a transition from street to courtyard while serving as a vegetated
infiltration basin fed from side-yard bio-swales. The permeable common
courtyard contains a shared terrace with a rainwater cistern below and a
children’s play area, as well an edible landscape of individual vegetable
gardens and a miniature fruit orchard. Dooryard gardens transition courtyard to
home. Each dwelling forms its own on-grade private terrace / garden which
extends the personal space of the home to the outdoors.
