Modern Eco Dwelling Unit in Beacon Hill

J_Beacon Hill DADU_Page_10

Seattle allows backyard cottages — legally referred to as detached accessory dwelling units (DADU) — in certain single-family situations.  These structures aren't without controversy but can helpful when taking on a renter or housing extra family.  BjarkoSerra Architects designed this DADU for a family in Beacon Hill, and it will be built in the next year or so to a Built Green 5-Star rating.

As shown in the rendering above, Beacon Hill DADU will have abundant windows for natural lighting, SIPs for an airtight and energy-efficient envelope, and rainwater harvesting for garden irrigation and stormwater management. 

Clad in Western Red Cedar, the project will also have roof-mounted solar systems for hot water and electricity and will be built with recycled and otherwise green materials.  I'll try to follow up with this DADU upon the completion of construction.  It will be beautiful.

    Looks promising. I wonder what it will cost. Personally, I think projects like this need to come in under or around the $100k mark in order to make much sense given their size and limited application. In many cases, you can buy a small cottage or cabin on some land for less than $100k and give it a green retrofit and be better off. Granted, the modular aspect may make it better for siting in the backyard of an existing home.

    bjarkoserra has done some incredible work here in seattle. this looks to continue that trend.

    it looks like the DADU is on the same lot as their recently completed beacon hill house.

    Where is the innovation, and Green ethic when you employ Western Red Cedar in it’s construction.

    Editors/presenters need to give more critical information on the designs. For example, at a minimum, the square footage and volume.
