Matchbox House LEED Platinum Certified – Ann Arbor
The project started out with an intent to design LEED certified which is reflected in its unconventional design. The project was modeled after a matchbox and was designed to have four inner quadrants that slip past on another withing the out sleeve of the house, all on top of
a raised foundation. The Matchbox’s compact design contributed to it’s LEED Platinum certification as there was less conditioned area to work on. The architect gathered information from other contractors experienced in green building practices in order to produce a home outside the norm. The result was distinctive, efficient, and compact home surrounded by natural, permeable turf minimizing the impact of the house on the surrounding environment.
The house has four bedrooms, 1,738 sf of conditioned space and a one car garage. It has received LEED Platinum Certification. It has a HERS rating of 47 and many notable features, including FSC wood, reclaimed trim from demolished Michigan barns in the region, no conventional turf (no irrigation) and low flow plumbing fixtures. The house has no attic or basement so upstairs rooms have dramatic ceilings that begin at 3’-0” and end at 16’-0” with an angle ceiling matching that angle of the roof.
No conventional turf or irrigation system was installed around the home, and all fixtures and fittings (toilet, faucets, and showers) are very high efficiency, reducing the site’s water demand by 78%. The wood used in the cabinets, stairs, closets, doors, and upstairs floors are all FSC certified. The house itself is much more compact than a standard house, so much that the LEED threshold dropped by 10 points. The kitchen counter tops and decking are constructed are composite from recycled materials.
The home’s unconventional design earned it 1st Place in Detroit Home Magazine Design Awards 2013 for Contemporary House under 4,000 sq ft.
