WBA was commissioned to design autonomous STR’s with common site amenities on two distinctly different sites in Yucca Valley – (see ‘Process’ tab for Master Plan details). For the Joshua Tree Site we evolved two distinctly different but related concepts of a single repeatable thermally-broken concrete form wherein a roof-cum-wall becomes the primal ‘cave’ with an expansive private / protected prospect bifurcated by one insulated-structural-glass-windscreen plane. In the ‘cave’ the foundation is an elevated pool-code plinth of shotcrete upon redistributed excavation, from which springs a mono-span open-edged dome upon an inflatable reusable form. The back of the ‘cave’ is for storage, counters, lounging, sleeping and washing. The interior is outfitted with islands for additional lounging, cooking, dining, and one privacy volume for laundry / WC that privatizes the main bedroom / bathing space. Arrival is on stabilized-decomposed-granite roads / drives into a vegetal enclosure of shade utilizing repurposed Joshua Tree stalks tied to a rebar enclosure. The Mojave Desert in Yucca Valley can be very hot of course but also extremely windy and very cold at times with periods of snowfall; so, while blocking wind and summer sun is an absolute requirement, so is absorbing and harnessing the sun in winter and shoulder seasons; whilst creating a solitary Mojave Desert experience in the most competitive and saturated STR market in the U.S.
