Designer: Kithaus is the latest endeavor of Los Angeles' Tom Sandonato, a veteran of retail design.
Look: Though the K4 is essentially a 187-square-foot aluminum-and-glass box, optional Ipê-wood louvers, decks, and canopies give it an equatorial vibe.
Installation: Delivery takes six to eight weeks, and depending on the terrain, this bungalow can be built on-site in as few as five days, without a foundation. Later on, connect your K4 to a second unit for more living space. From $40,000
weeHouse by Alchemy Architects
Designer: The go-to firm for the Twin Cities' creative scene (hip lofts and boutiques), Alchemy Architects has widened its fanbase with its weeHouse series.
Look: The weeHouse's oxidized-steel or pine-plank sidings were inspired by Little House on the Prairie and Donald Judd. Starting at 435 square feet, one can be customized with hanging fireplaces and oversize tubs.
Installation: Depending on size and your layout tweaks, the crash pad can be sheltering guests in six months. From $79,000
Rincon by Marmol Radziner
Designer: L.A. studio Marmol Radziner has used its celebrity cred (manses for Tom Ford and Ashton Kutcher) to upgrade the factory-built-home category.
Look: Its Rincon model is a 600-square-foot one-bedroom complete with walnut cabinetry and Kohler fixtures. Add-ons like Heath Ceramics tiles and polished concrete floors make it even more decadent.
Installation: Because of the finishes, the pied-à-terre takes six to nine months from design to assembly. From $250,000
E.D.G.E. by Revelations Architects
Designer: After 30 years as a traditional practice, Wisconsin's Revelations Architects unveiled its earth-friendly E.D.G.E. house.
Look: The roughly 500-square-foot E.D.G.E. owes its appearance and eco-mindedness to slatted-oak sliding doors and a mid-century-style fly roof—the former insulates, the latter harvests rainwater.
Installation: Your E.D.G.E. will arrive in about a month (so start pouring a foundation now), and the barn raising takes as little as a week. From $100,000
