Home Plan Collection

D+A Studio has a stock Home Plan Collection, featuring plans ready for permit and construction. All of the plans can be viewed on our website, as well as pricing information.
(Our website is temporarily down, please view all plans below. Scroll to the bottom of the page for pricing information.)

Many of our homes are perfect for Accessory Dwelling Units (ADU's), backyard cottages, or alley flats. Most plans come with both modern and traditional options. Each plan is ready for permit and construction or can be customized to meet your unique needs, for a fraction of the price of designing a custom home from scratch. 

See a brief description of ADU's and guidelines for Seattle and King County here.
