H2D’s Seattle green custom home is complete!

H2D Architecture + Design recently completed a new green custom home in the Bryant neighborhood of Seattle.  The homeowner came to H2D Architecture + Design with a book and a vision.  The design was born from a collaboration of these early ideas – the book about Japanese cabinetry design in maximizing every square inch of space for some specific use and the vision of sustainably building a new family home.

The 3000 square foot home was designed and built with environmentally friendly construction methods, efficient design to utilize the whole volume of the home, and utilizing low-toxicity sustainable materials.  Throughout design and construction, Heidi Helgeson, principal architect, worked closely with the homeowner and contractor to consider and confirm that the design decisions aligned with the goals for this home.  This home provides clean indoor air for its occupants, utilizes locally produced, low-toxic, and salvaged materials, has a low impact on the site through water collection and green roofs, and has an energy efficient building envelope.  The home was featured on the 2012 Green Home Tour in April.  Learn more about the design process and see construction photos along the way.
