Have you designed a house, or even just a room, to accommodate the needs of older or handicapped people?
“Aging in place is important to South Mountain,” said John Abrams, CEO and founder of the West Tisbury integrated architecture, building, and renewable energy firm. South Mountain recently completed a 715-square-foot home in West Chop Woods (bit.ly/SoMoWChop) that illustrates the provisions they incorporate for aging in place.
The company has created a three-tier checklist they present to all homeowners during the design phase (see box, next page).
Level 1 includes such features as at least one bathroom on the first floor, weather protection from elements to fully cover accessible entry door, and minimum 38-inch wide halls. Level 2 has such specifications as “Turning radius of 60 inches, or space for a T-turn in kitchen, full bathroom, bedroom, and living/dining area,” (to accommodate wheelchair users), and “ability to operate windows from a seated position.”
Level 3 advocates for using integrated rolling carts in place of base cabinets in the kitchen, to accommodate a wheelchair user; power-operated windows, and electrical outlets at a minimum of 18 inches high.
“We aim to incorporate all Level 1 provisions in every project we do. Should further accessibility be of interest, Levels 2 and 3 provisions can be incorporated at an additional cost,” said South Mountain architect and co-owner Matt Coffey.
Three-tier checklist for “Aging in Place” design. “Visitability” gauges the ease with which a person with disabilities could access a building. See the complete list on their site, here: bit.ly/SoMoAging
