The overall goal is to design a building that is of its time, but timeless in its response to the context, as well as didactic in its expression of its high performance systems. The proposed building is a five-story, cross laminated timber (CLT) structure designed to the Living Building Challenge (LBC) guidelines. The ground floor uses include retail space on SW 1st Avenue and SW Pine Street, an office lobby on SW 1st Avenue, a bike hub including bike storage, showers, restrooms and lockers for tenant use, and mechanical and electrical space. The second through fifth floors will be office space. A single tenant is currently expected to lease the third, fourth, and fifth floors. The second floor can be leased to a single tenant or divided for two tenants. The building gross square footage is 58,733. The proposal engages the street environment through the creation of retail frontages along both SW 1st Avenue and SW Pine St. These retail lease spaces are connected to the street environment with storefront glazing to promote visual connection and a sense of transparency, welcomeness, and safety at the street edge. Building support services are located away from street frontages to maintain an active street front. This building includes onsite waste water treatment and storm water capture reuse required to meet Living Building performance goals. Levels two through five are planned as office space with access to natural light, views, and natural ventilation. The roof will be used for rain water collection and PV generation. Roof area for PV generation is intended to be maximized to meet energy demand. We are looking forward to the opportunity of coordinating it closely with the Design Commission and City of Portland. 01ZGF Architects PAE | Living Building 4 Project Goals 1. A mixed-use building designed to revitalize and complement the Old Town/Skidmore Historic District • Activate the historic district with infusion of jobs and people • Replace a surface lot with active ground floor uses • Restore the historic street character and enhance the public realm 2. A Living Building that is net zero energy, net zero water and red list free: a building that uses only the resources available to its site • Help city achieve 2030 Climate Action Plan • Mitigate climate change that puts historical district resources at risk • Showcase Portland as a leader in Living Buildings 3. A replicable, developer-led solution that can inspire future Living Building development • Create a financially viable building • Share approach to encourage future sustainable development ZGF Architects PAE | Living Building 5 Living Building Challenge Living Building Certification (LBC) is the world's most stringent sustainable building standard, moving beyond "less bad" and towards buildings that are truly regenerative and contributing positively to society. Currently there are only fifteen certified Living Buildings in the world, with only two in Oregon (and none in the city of Portland) After over 10 years, the scarcity of certified projects testifies to the difficultly of creating truly sustainable projects. To realize a project, it requires not only enlightened owners and investors and a talented integrated design team, but also the support of the local community and municipality to address areas where its requirements may conflict with local regulations. The system is organized in seven "petals" that encompass twenty mandatory imperatives that address: Place Health The project is designed for people, not cars, will include extensive bicycle Every occupant will have access to fresh air and daylight through a nearby commuting amenties as well as onsite urban agriculture. An acre of natural operable window.

Per the LBC exception for dense, energy intensive buildings solely for human delight and the celebration of culture, spirit, and place, on small urban lots, over 75% of the solar panels will be onsite, and the as well as educational elements designed about the operation and remainder supplied by an additional installation within the local grid. performance of the project. Materials The project will contribute to the local economy by sourcing at least 50% of materials locally or regionally, selecting the most sustainable and healthy materials possible by avoiding common toxic materials (like PVC and zinc) on the LBC's Red List.

The district is comprised of a relatively fine grain urban grid. The 200 foot square blocks are typically subdivided into smaller parcels. Multiple individual buildings typically comprise a block face, full block developments are uncommon. The proposed project utilizes two joined parcels, the first being roughly 100 feet by 100 feet square at the corner of SW Pine and SW 1st Avenue, the second abutting to the north with a 17 foot frontage on SW 1st Avenue and depth of approximately 100 feet. The building footprint occupies just over 1/4 of the block. 1/16” = 1’ - 0” 0’ 4’ 8’ 16’ ZGF Architects PAE | Living Building 9 Street Wall S/OTDG: A2, D2 CCFDG: A7, B1 A defining characteristic of The Skidmore Old Town Historic District was a development pattern that resulted in a strong and continuous street wall. The street wall is comprised of facades that are strong at the street level but also on upper stories, strong rhythmic fenestration with a balanced ratio of wall to window surface and clear visual delineation between floors. The proposed project reinforces the continuity of the historic street wall by developing a strong and rhythmic facade that meets the lot line and extends to the building's full height. Fenestration is rhythmic in nature and articulated to express floor levels and key proportional datums found in the district. ZGF Architects PAE | Living Building 10 PL PL J MECH. H EQUIP.
