An airtight building envelop helps naturally insulate the structure. The appliances in the house are energy-efficient, and use greywater recycling.

There are two zones in the house. One side, which the architects refer to as the "buffer zone," faces north, capturing the sunlight in the winter and pulling it into the house. In the summer, it traps the harsh sun so less gets into the living space. Edible planters adorn the wall.

Australian firm Archiblox built the world's first energy positive prefab and then displayed it in the middle of Melbourne's city square for all to see. The house has large double-glazed windows that bring sunlight and warmth into the structure during winter. The garden walls also wrap over the roof of the structure to further insulate the home and act as a living roof.

The houses uses sustainably-sourced materials with formaldehyde- and VOC-free finishes.

In-ground tubes also help with ventilation, pulling cool air through the house from the south side.

This 3,200-square-foot structure was assembled with a prefabricated foundation, concrete panel siding, and efficient built-ins, minimizing construction debris and toxins—such as concrete foundation tar—on the site.

The house's large, double-glazed windows are used to bring sunlight and warmth into the structure in the winter. Sliding walls of vertical planters act as shading devices in the summer.

When Abbie and Bill Burton hired Marmol Radziner to design their prefab weekend home, their two requests were “simple-simple, replaceable materials,” says Abbie—such as concrete floors (poured offsite in Marmol Radziner's factory) and metal panel siding—and “the ability to be indoors or outdoors with ease.” Deep overhangs provide shade and protection from rain, so the Burtons can leave their doors open year-round and hang out on their 70-foot-long deck even in inclement weather. They visit the house once a month, usually for a week at a time, with Vinnie and Stella, their rescue Bernese Mountain dogs. Their two adult children occasionally join them. The couple hopes to one day retire here.

According to Remijnse, since the only direction they could build on the small site was up, they decided to add height with a gabled roof.

Studio owner Joey Williams uses his space to work from home as an Austin-based media director.

The other unit is a conference room with bamboo floors.

In 2003, Resolution: 4 Architecture was one of 16 firms who participated in the Dwell Home Design Invitational—a competition to design a modern prefab home for $200,000. Their winning design, constructed in Pittsboro, North Carolina, is a groundbreaking case study that combines prefabricated construction with contemporary, modern design.

Heating for the unit is provided by a Spartherm fireplace, with electric heating integrated into the magnesite floor. Walls are insulated with fire-tested wool felt under plywood panels.

Subtle features incorporated into the design, including an elevated terrace and jetty, help the home float above the island.

The L-shaped secondary building perches over a craggy escarpment. It offers the best vantage point for taking in the moss-planted roof, forest, and ocean.

It takes three to five days to install a Vipp Shelter onsite.

NOEM, a Barcelona–based architecture firm, created a metal-clad house for a young client just outside Madrid. It’s raised 12 feet off the ground to offer better views of the landscape, lending it "the futuristic feeling that it just landed," says Pol Guiu, one of NOEM’s cofounders.

A skylight was added to bring in more light, and the existing ceilings painted Benjamin Moore ‘Black Tar’ for contrast. The island pendant is the Schoolhouse Ray 17” Pendant and the stools are the Artek Aalto High Chair K65.

Australian firm Archiblox designed the world's first carbon-positive prefab with interiors filled with sustainably sourced plywood with formaldehyde- and VOC-free finishes.

Even in a small space—this unit is one of the company’s smallest—there’s plenty of room for a sitting area. In addition to montoread and charred wood, this space has American Clay walls, a soft plaster-like coat that when punctured or cracked, a spritz of water will allow minor flaws to be smoothed clean.

Sett Studio also does complete interior work. This unit features monotread, which are panels made from milled recycled wood, on the floor, walls and desk. Lately, the company has been using more bamboo.

Built with a steel frame, the Frost House features panels of styrofoam between aluminum sheets for the exterior walls and styrofoam between plywood for the roof and floors. Bold, primary colors accentuate its geometric form. Shortly after Karen Valentine and Bob Coscarelli purchased the home in 2016, they began to unearth nuggets of information about its pedigree. Their realtor had provided a brochure that identified the prefab as designed by architect Emil Tessin for the now-defunct Alside Homes Corporation based out of Akron, Ohio, which had held a patent for the structure’s aluminum paneling. Their new neighbors provided a stack of Alside Homes sales materials, floor plans of various models, and even a script that had been written for salespeople during home tours. They determined that the Frost House had been a sales model for the company, and that Tessin had been the son of Emil Albert Tessin, the legal guardian of Florence Knoll.

Renowned designer and architect Jens Risom sourced parts from a catalog for his customized A-frame and had them delivered in pieces to his remote island site off Rhode Island, helped to raise the aesthetic profile of modular construction.

All of Scott Palamar’s selections and customizations brought the total to $150,000 for the 640-square-foot home and surrounding land. “I feel like I struck on such a novel solution because I was able to afford a home tailored to my lifestyle,” he says.

The Japanese "no-brand" masters of minimalism unveil the first single-story design in their line of prefab homes.

Christopher: Olalla, Washington, is a small rural community on the Kitsap Peninsula accessible to Seattle via ferry, or a long drive through Tacoma. We're about one mile from Puget Sound, one mile from a freshwater lake and a few miles from a popular sailing harbor. We're Olympic Peninsula adjacent, and, most importantly, we are less than 45 minutes from Amy's favorite oyster farm in the Hood Canal, Hama Hama. In addition to a family of deer, dozens of birds, and hundreds of frogs, our property is also home to occasional wandering coyotes and a very strange-looking creature that Amy has convinced herself is a chupacabra. There are cougars and black bears in the area as well, but thank God we haven't eyeballed them yet. Amy: For us, the primary driver for us to move from Los Angeles and abandon our urban existence was our love of the property.

This dreamy, glass bedroom by the lake was created as an early prototype for the prefabricated greenhouse/she kits known as the Kekkilä Green Sheds.

Helsinki architect Ville Hara and designer Linda Bergroth collaborated on a prefab shed-meets-sleeping cabin, which can be assembled with little else than a screwdriver. Bergroth, inspired by nomadic yurt dwellers, wanted an indoor/outdoor experience for her property in Finland.

Six-inch-square blue tiles cover the walls and floor of the girls’ upstairs bathroom. The towels and rug are also by H&M Home.

"How would a kid draw a house?" architect Per Franson asked himself when designing the Olivero-Reinius family home. The simple prefab structure’s unusual color comes from a traditional source: falu rödfärg, the historic mineral paint that gives the region’s famous barns their red color.

The inspiration for this prefabricated, modular family home on Fishers Island, New York, were the views that Tanney and Luntz saw from a 12-foot stepladder, which was balancing on the bed of a pickup truck when they first visited the site.
