Mission Hill Site

Innovativ(E+) Ideas – Engaging the topography to the utmost, SMS proposed an entirely green roof/solar farm structure.  From Parker Street the site appears to be a community garden & park, while  along Terrace street sits a three-story, mixed-use, multi-family housing structure.

Community Garden Design
Not a Building, a PARK. Our proposal integrates landscape and building into a single system by taking advantage of the dramatic change in elevation from Parker to Terrace Street. From Parker Street, residents do not encounter a building but, rather, a productive landscape that accommodates a community garden, a solar farm, and an art park. The landscape is punctured from below by a series of community courtyards that gradually step down to Terrace Street, providing a dramatic footpath from Parker and access to the residential units below.

The upper community gardens lead to a series of courtyards, both public and private, with centralized green spaces at the center of the spaces to create a favorable microclimate that invites us into the shoulder seasons. The courtyard spaces transition from more generously scaled spaces with open green areas to an intimate scaled garden spaces. The use of photovoltaic lights, porous pavements, local materials, and indigenous plants are all planned to illustrate sustainable practices to the community. 

Building Design
 Twelve different residential unit types enrich the diversity and sustain tenancy. Each spacious and flexible unit opens onto a private garden, always allowing the conditioned space to breath. This outdoor private space is valued as much as any interior space.  Furthermore this vegetated space brings us back to the intimate connection with nature. The relationship between the open & enclosed-green space and the built massing, shape the courtyards to produce a wide range of experiential conditions. This dialogue filtered by native trees and vegetation creates an active building energizing all outdoor categories, through farming, and public & private spaces.
Sustainable Design
 Our project incorporates a 15,000 sq.ft community garden on its roof. This roof garden helps insulate the building and is the first step in a water filtration process that naturally filters and stores rainwater onsite for re-use. Residential and retail units enjoy natural ventilation and are accessed from courtyards, reducing conditioned circulation space.

A 14,500 sq.ft solar farm provides electricity for the energy efficient residential units and retail space. The PV panels are freestanding from the building, so that as the efficiency of the panels increases over time, the solar farm can be converted to more productive uses. Heat is provided through a geothermal heating system and is distributed through radiant heating in the floors. The residential and commercial units feature R-46 super-insulated exterior wall construction and triple-paned efficiency windows. Through these strategies and others, the design achieves a projected energy surplus of 21% and a LEED score of +123 points.
