Designed to be certified LEED Platinum and with energy performance as a near-net zero energy home, this duplex alongside Boulder Creek is a modern rowhouse embracing the city on one side and nature on the other.  Invited in through a wide, welcoming front porch one is led through a contemporary open living plan to a folding wall that disappears to capture the sounds of Boulder creek below.  Built of stone, wood, and concrete, this home strikes a balance between the warmth of material and the character of an urban townhouse.
