We've been working on another compact design for a Central City Austin backyard. This casita is a two story, 2 bedroom, 2 bath compact accessory dwelling that meets the City of Austin development standards and would be an easy stick build or prefab (modular, panelized, or SIP) for most any city or countryside site.
Entering into the kitchen end of a very compact "great room" (kitchen, island/dining, and living room) one can immediately proceed past the living room and the woodclad downstairs bathroom into the small bedroom, or climb the stairs conveniently housed in the clerestory-lit stair saddlebag to enter the upstairs master suite and it's attached covered porch.
The upstairs suite is fitted with a modest walk-in closet, and a clerstory-lit master bath, with tiled tub and separate shower surround. The master bedroom has views out an 8'x8' slidng door onto the 8'x14' covered second floor porch and a countervailing view out a similarly sized composition of operable and fixed windows in the adjacent wall.
Large floor to ceiling and wall to wall sliders (a nice trick to make tight rooms seem more spacious) allow easy visual and physical access from each of the main downstairs spaces onto a sheltered shallow patio space, and further help to punctuate the composition of the contrasting vertical wood and snap-lock metal siding with Polygal clerstories. This creates an easily buildable and simply detailed exterior skin that taughtly wraps the 14'x32' minimal footprint of the building, making it an ideal self contained retreat for most any site. Shed roofed saddlebags, housing stairs, a cantilevered closet, and a shallow patio, give visual complexity to what is a very simple and carefully considered compact design.
