For many groups of faithful friends, adulthood means accepting that logistics are often the biggest obstacle to maintaining relationships. As hard as it is to get the gang together for dinner when everyone lives in the same city, it becomes a Herculean (or Sisyphean) task once the winds of change have scattered everyone to lands afar. Rather than succumb to the inevitable growing apart, four close-knit couples in Texas came up with a clever way to live together while maintaining their independence. They've built themselves four tiny houses all in a row, each within a stone’s throw of the next.

Because nothing says friends forever like signing a deed together, eight great pals living in the Austin area purchased ten acres of land outside the city limits, near the Llano River, for what they dubbed the “Llano Exit Strategy.” With a plot of earth to collectively call their own, the environmentally minded landowners enlisted the services of architect Matt Garcia to design four identical residential structures, one for each of the families. In keeping with the pragmatic minimalism of the “tiny house” movement, the homes comprise a mere 350 square feet apiece, with one bedroom, one bathroom, and one living room.

Where the friends’ extremely private community breaks from tiny house tradition is the existence of a fifth building: a big 1500-square-foot cabin with a full kitchen and additional social space for the neighbor-friends to come together as they please—think of it as a ground-level tree house, or a college residence hall lounge with nicer furniture. There are two dishwashers, presumably to avoid fighting over anyone leaving their silverware out too long, a porch, picnic tables, and even six bunk beds to accommodate lucky guests.

It’s not hard to see why the couples chose the Llano River as the site of their ideal idyll. They “had been hunting for a quiet escape from the ever-growing buzz of Austin, a place to ride their bikes, reconnect with nature and recharge,” and the riverfront location checks all those boxes. They’ve made sure to respect their natural surroundings by working with the arid local climate, rather than against it: the homes’ sloped butterfly-style roofs catch rainwater for reuse around the compound, while metal siding and good insulation both reduce heat from the glaring summer sun while preserving indoor warmth during cooler months.

The couples haven’t yet moved to their shared property full-time, escaping their busy city lives mostly on holidays and long weekends, but they do plan to retire there. What a way to grow old together.
