Parametric DADU: The Casita

Interior Rendering of The Casita

As part of Seattle Architecture Foundation’s 23rd Annual Architecture Model Exhibit, Iterations, we submitted our latest standalone tiny house: The Casita. This Detached Accessory Dwelling Unit (DADU) was developed in 2019 as part of our ongoing research into solutions for Seattle's housing shortage while balancing different clients' needs. With the innumerable iterations this componentized house offers, clients can easily choose the number of bedrooms, solar orientation, or exterior materials with the web-based tool we're currently developing for beta-testing. The digital model automatically updates once parameters are set, and eventually this program will be able to produce construction drawings and a bill of materials.

A snapshot of the parametric beta site. Users will have the ability to design their own DADU.

A prototype of the Casita is being built, with contribution from several JA staff members, on Ray and Mary Johnston's property in the Methow Valley. The Johnston’s presence in the Methow began with their home away from home, the Twisp Cabin. From there, they expanded to other projects for numerous clients, and now they’ve returned full circle to create this practical prototype for their own use. The design consists of two areas, a studio-apartment sized living space and a sauna, and includes an outdoor shower and screened porch— a perfect space for any outdoor enthusiast to come home to!

To take a virtual tour of the model and to see firsthand how the web-based program will work, head to our project page on SAF’s website.
