Townhouses are a dream urban project, combining the best aspects of single family, and urban apartment residences. The opportunity to carve out a special place for a family within the urban environment. They are also excellent candidates for sustainable building practices including green roofs, on site renewable energy, and high performance envelopes. Driven by the unique requirements of vertical living. Emphasis is placed on flow within and between floors. Opportunities to draw daylight into the building are sought out, and efficient use of space is maximized. Precious exterior spaces are created and amplified, and connections between roof decks and garden spaces are emphasized. Scale and materiality are used to knit the facades of the building into its neighborhood.
