3 The Proposal: A Courtyard Building Typology Precedent Projects The proposal is for a 100% secured rental development comprising 36 units ranging from studios to one, two, and three bedroom units. ontext + Approach The siting concept is based on a courtyard and roof garden typology, where all units benefit from a strong relationship to fresh air, natural light, landscape, and usable outdoor space. The architecture character and massing will implicitly take cues from the context, yet be confident of its age through its bold simple contemporary vocabulary. Landscape is key to addressing issues of adjacency and context to the surrounding neighbourhood. The approach of the development is to integrate and weave landscape into the built form.

4 View from southwest View from northeast orm + Development Massing The density and massing responds to the transitional nature of the site which bridges between the adjacent commercial/multifamily and First Shaughnessy zones. A predominantly 2 storey massing on the west side of the site, steps up to 4 storeys along the east to match the commercial, mixed-use building across the lane. View from northwest: massing stepping down Entrance The principal entrance and address to the development is located at the south-west corner of the property along West King Edward Avenue. This is the location for visitor and parcel delivery as well as emergency services response. Four walk-up townhouse style units front directly onto West King Edward Avenue. Informal entrances along the laneway provide secondary everyday access for tenants and contributes to the principal of eyes on the street. Frontage Along West King Edward Avenue the walkup townhouse style units are pushed to the east side of the site to provide a 6.4 meter wide setback for filtered viewes into the site, layered landscape treatments and a primary pedestrian entrance to the development. The third floor of the townhouse style units steps back to reduce the massing along the sidewalk and street edge. View from the east: activated laneway Edges The massing along the western edge of the site is 2-storeys and set back from the adjacent property by 4 meters to allow area for a pedestrian walkway and mature landscape buffering. The northern edge of the building steps back on the upper floors to reduce shadow casting. The massing along the eastern edge is 4 storeys which matches the height of development across the lane. Courtyards Three interior courtyards are used to bring natural light and ventilation deep into the center of the development while providing shared spaces for communal rather than private use. Opening these courtyards to the laneway together with landscape treatments and secondary entrances regenerates the utility lane into a mews-like character.

8 FAQ s Q: What are you proposing for the site? uestions + Answers A: We are proposing 36 units of affordable rental housing with a development density of approximately 1.47 FSR. The development will be comprised of 28,000 square feet with a mix of studio, 1, 2 and 3 bedroom suites. The form of development is based on a Courtyard Housing typology where landscape plays an important role. Q: If a maximum of six storeys is allowed, why is the application for a maximum of four storeys? A: We prefer to pursue a responsible density and massing in keeping with the surrounding neighbourhood which includes the mixed use building to the east. Q: Are you designing the market rental housing with a specific tenant in mind? If so, who? A: No, we want to provide secure family rental housing to give people an opportunity to live and raise their family in close proximity to where they work. This would include people working in the healthcare industries, in the downtown core, and at UBC. It may also include empty nesters who wish to downsize but stay in the neighbourhood. The development will be designed to promote community building by allowing residents to raise their families and age in place. Q: What changes, if any, have occurred as a result of your public consultation to date? A: The team has worked to reduce the overall massing of the building on the south, west and north edges. Primary Entrance A: In order to address questions relating to landscape design, the team has worked closely with our landscape consultants to improve and develop a consistent landscape strategy along all edges of the site. Specific attention has been given to the courtyard design. A: The team has hosted several developer-led neighbourhood meetings for information sharing and feedback. Q: Will you be incorporating green building practices into the proposed design and landscaping? How? A: The proposal targets all Three Pillars of Sustainability: Socially Sustainable the mix of unit types will provide opportunities for a healthy 2-3 P lifestyle for single professionals, families and elderly members of the community which will provide a positive contribution to building a sense of community. Environmentally Sustainable residential dwellings will be constructed to match LEED Gold standards, and will meet or exceed all stringent guidelines for water conservation. Economically Sustainable both street oriented townhouses and condominium dwellings provide more affordable opportunities for young families and downsizers to move into the neighbourhood. As a rezoning project, this development will meet a minimum LEED Gold standard. 2 Parking Entrance 4 2 Secondary Entrance Secondary Entrance Q: How will the project address landscape design and character both within the site and within the context of First Shaughnessy? A: Much of what gives Shaughnessy its distinct character is incorporated in the landscape design. The mature trees along the western property line are retained. The plantings that are located to provide screening yet allowed filtered views into the property. Layered plantings along King Edward Boulevard create a sense of depth. High quality materials such as low stone walls, metal fencing and stone paving are proposed. Finally the landscape design reinforces entranceway through the use of garden walls, trellis structures and garden gates storey townhouses 4 2-storey 1-2 bed units 4-storey 1-3 bed units Q: How will you address parking on the site? A: Parking will be accommodated underground. Sufficient underground parking will be available to accommodate residents and visitors. There has been discussions about an overall parking reduction. Entrance and exit to the building will be along the side commercial lane which feeds directly to Oak Street and King Edward Avenue.

10 Three Pillars of Project Totals (pre-certification estimates) 110 Possible Points Materials & Resources 14 Points ustainability Sustainability Social, Environmental and Economic. A series of common courtyards tie interior to exterior, architecture to landscape, in support of these pillars: Socially Sustainable Positioning unit entrances off of semiprivate courtyard spaces increases the likelihood of crossing paths with one s neighbours. The mix of unit types will provide opportunities for a healthy lifestyle for single professionals, families and elderly members of the community, while at the same time making a positive contribution to the local neighbourhood through community building. Environmentally Sustainable The courtyard typology brings natural light and cross ventilation to a majority of the units, with the potential to significantly reduce artificial lighting loads and heating/cooling energy. Other passive design elements include calibration of key facade exposures, deploying shading and balcony overhangs for solar protection. 0% 25% 50% 75% 100% Internal Courtyards aid with passive natural ventilation and lighting Sefaira Analysis illustrating percentage of occupied hours where illuminance is at least 28 footcandles, measured at 2.8 feet above the floorplate Daylighting Analysis In addition, this Rezoning Application will participate fully in the LEED Program with a LEED Gold minimum target, and will meet or exceed all stringent guidelines for water conservation and energy use. High quality, durable, locally sourced materials will be utilized where possible, and the predominant wood superstructure seeks to minimize the embedded material carbon footprint. Economically Sustainable Street oriented townhouses and condominium dwellings provide opportunities for young families, single-parent families, students, young professionals and downsizers to enrich and enliven the neighbourhood. As a one hundred percent rental building, the project offers a significant increase to the rental stock in central Vancouver. This increase in rental opportunities at a key crossroads adjacent to the Women s and Children s Hospital and connecting transportation networks promotes an economically sustainable local economy.

The Sefaira plugin for SketchUp analyzes the environmental performance implications of design decisions in real-time, at the crucial early design stage. The software asseses a three-dimensional computer model to distinguish between floor, roof, exterior and interior walls, and glazing, and produces energy and daylighting metrics. In combination with other parameters such as local energy sources and tarifs, fixture type, insulation values, and heating type, a complete environmental impact assessment is created, which was utilized to inform the design.
