Madrid-based firm PKMN dreamed up this flexible concept for a client with a tiny home north of the city. Made up of three shelving units on track system, the All I Own House can be configured in countless ways, making space for a bedroom, kitchen, sitting area, changing room, and more.

The custom cedar tub, fabricated by Dovetail, elegantly fits into the master bathroom.

The walnut staircase and slide in a Chicago town house leads from the main level to the basement. To protect people on the ride down, a “crash pad” fashioned from a standard gymnastic mat covers the wall at the slide’s base.

Hexagonal tiles made by the Portland Cement Company continue the pattern in the bathroom, where the architect designed low drawers and cabinets that are easy for Luna to reach.

A corrugated metal roofing, pine walls stained a warm blonde hue, and an abundance of glass make this modern prefab feel much roomier than its 1,600-square-feet size.

An abundance of modular and multifunctional furniture, like this table with built-in sliding chairs, means the space is constantly evolving.

The fireplace that Lake|Flato designed for the deck is the compound’s focal point. “People can go tuck their small kids into bed and then creep back to the fire pit area and be gregarious late into the night,” Wallace says.

Tagliabue made sense of the soaring volume in the library by installing double-height custom bookcases that can be accessed via a catwalk.

Ryan Anderson of RAD Furniture designed the stools as well as the table and benches on the pool deck.

The Lowreys worked with architect Luis Sánchez and a team of local craftsmen to complete the build. The custom counters in the kitchen are terrazzo and granite; the oven and cooktop are from Teka.

In the living room, spare Scandinavian design takes center stage. Hans Wegner’s Wishbone chairs surround an Essay dining table by Cecilie Manz for Fritz Hansen; a mostly wood palette is enhanced by slate-gray brick around the fireplace.
