Prefabulous Small Houses

Prefabricated homes used to be considered inferior to houses built on site, but not anymore. In Prefabulous Small Houses, best-selling author Sheri Koones presents 32 stunning prefabricated homes , including Greenfab from around North America. 250 beautiful photographs and floorplans show the amazing breadth of styles available to today’s homeowners.

Small is the new big.

Everyone from Millennials looking to buy their first homes to Boomers trying to downsize have turned to small houses in recent years. These homes cost less to build, less to heat, and less to maintain. All of the houses in Prefabulous Small Houses range from 325 sq. ft. to 2,000 sq. ft. and showcase construction methods perfect for any climate.

Building better, building greener. 

All of the houses featured here are highly energy efficient and are built with sustainability in mind. In eco-friendly prefab construction, local materials are used when possible, metals and wood are recycled, and houses are built with a conscious attempt to preserve the land on which they now stand. A foreword by actor and environmentalist Robert Redford speaks to the urgency with which we must act to combat climate change and how prefabricated small homes have a role to play in that challenge.

Premier Builder - Architect & Design

With the growing trend of simple living, it’s clear that Americans are re-shaping what it means to live the “American Dream.” The desire for more possessions and square footage is slowly being replaced with a craving for quality and freedom. Homeowners are finding liberty in downsizing their lives and spending money on what really matters– the fundamentals that cannot be replaced.

For most, these include health, enjoyment and the betterment of the world. We’re starting to ask questions like “what will improve my quality of life?” and “how are my buying decisions impacting the world?” There’s been a rising focus on mindful consumption; making our buying decisions based on the longevity of a product, how it was made and how it affects the planet.

Bernie Yee and Stefanie Smith couldn’t find the right modern space in Greenwood. So they had one made to order. Full artcile on Seattle Met

WHEN BERNIE YEE and his wife, Stefanie Smith, moved from New York to Seattle in 2012, after Bernie took a job with video game company Bungie, they had a few specifics in mind for their first home: a modern, energy-efficient house with enough room for their son, an attached mother-in-law apartment to rent out, and a work space for Stefanie’s massage therapy practice. All of this, ideally, in a nice, single-family neighborhood. 

Prefabricated homes—structures built off site, then placed on top of a property using a crane—have plenty of modern perks, says Johnny Hartsfield of Greenfab, which built Bernie and Stefanie’s home. Constructing in a controlled indoor environment protects building materials from the elements and allows for more precise structural engineering and cost control. “So you got the health, you got the strength, and then predictability,” says Hartsfield.

Dwell - House of the Week: "Nearly Net-Zero Prefab Installed in 29 Hours. To assemble a house in a day is a feat in itself. Constructing a near net-zero energy house in a day is a major design/build achievement. The prefab firm Greenfab rose to the challenge with a variation of their 1700 Series model - packed with energy-efficient features - that came together in just one day (though required a few more weeks to finish minor details)". Read the article

We’re about smaller homes that can adapt, not homes as throwaway commodity,” says Humble, of HyBrid Architecture/Assembly. His home was a collaborative project between Hybrid and modular homebuilder Greenfab. 

The home has windows in all the right places, making the narrow house feel bigger than its 20-by-36-feet limitation. They also provide for passive heating during Seattle’s long chilly season. The home was the 1St LEED platinum Modualr Home in the State of Washington and also has a Built Green five-star energy rating.

Those in the industry say they're cheaper and more environmentally friendly, and can be ready to move into within a day. "Would you want your car to be built in your driveway?" says Koones, of Greenwich, Conn. "Of course you wouldn't. You want your car made in a climate-controlled factory by skilled professionals on an assembly line. Wouldn't you want the same thing for your home?"

"inHabitat" Today, Greenfab was awarded LEED Platinum certification by the USGBC for achievement in green homebuilding and design. Greenfab’s prefabricated, modular home is the first to be certified LEED Platinum in the state of Washington, and it features healthy living spaces, sturdy construction, and a completion rate that is 50% faster than traditional homes built on-site. The home is part of Greenfab’s 1300 Series, which is now available nationwide.

treehugger: March the 7th

"tree hugger" People often complain about LEED, wondering what is the point of spending all of that money on a plaque. But the real deal with LEED is that it is a third party certification to a tough and evolving standard. That's why, in a week when the Ideabox IKEA prefab is getting all the media exposure, it is appropriate to get beyond home show hype and look at a real house on a real piece of land. Like this 1300 series from Greenfab, the first to be certified LEED Platinum in the State of Washington.

Jetson Green: March the 5th

"JetsonGreen" Greenfab was awarded LEED Platinum certification for this modular home, a contemporary residence located in the Jackson Place neighborhood of Seattle. It’s the first prefabricated, modular home in Washington to obtain this level of LEED certification and the design is part of Greenfab’s 1300 Series now available nationally.


Super Models

Modular homes, which have been around for a few hundred years, are adopting an ultra-green identity.

A prototype Seattle home offers an unusual gift: graywater recycling. Greenfab’s premier prefab house took three-and-a-half months to build: 14 days in the factory, one day to install, and three months to finish. But the business model was years in the making. The goal: to create a house that is healthier, stronger, and more energy efficient than its stick-built counterparts. “Ours may have a similar sales price to other new homes on the block, but it offers more value in energy efficiencies and innovation,” says Greenfab founder Johnny Hartsfield.

The 1,790-square-foot, three-bedroom house is also extremely efficient. Exterior walls (R-26) are covered in rigid insulation and spray foam. A hybrid water heater supplies hot water, and a mini-split heat pump takes care of heating and cooling. There is also pre-wiring for a 2.4-kW PV system—enough to offset a quarter of the energy use.

Prefab Redux: As housing recovers, prefab homes could set off a new, green wave.

Now, with the economic recovery gathering steam, there has been renewed interest in using prefabricated manufacturing techniques to make modern, green designs more accessible to home buyers. Several new companies are promoting the approach in Washington, among them GreenPod Intelligent Environments in Port Townsend; Seattle-based Greenfab, which installed a seriously efficient modular home in the Central Area in January (expected to achieve LEED Platinum certification).

Prefab is also more appealing in lean times. Kaufmann thinks that the intersection of the current housing market, financial market and boom in environmental awareness has helped shift the mentality of home buyers away from the two-year flip (moving up the ladder to larger and larger properties) and toward a philosophy of efficient, smaller homes that will last.

An urban lot in Seattle’s Jackson Place neighborhood was recently infilled with a super green prefab designed by HyBrid Architecture and built by new prefab maker Greenfab. Aiming for LEED Platinum certification and net zero energy use, the three story home combines solar power, rainwater collection, urban agriculture and prefab construction. The model home was completed at the end of February and is open for public tours until the end of March.

Stylish Greenfab Home Unveiled in Seattle

I recently mentioned the construction of Greenfab‘s model home in Seattle, and that home is now complete. I think you’ll agree, it’s just as warm and handsome as the renderings. The six-module abode — on target for LEED Platinum and Built Green 5-Star certification — has 1,790 square feet with three bedrooms, two and three-quarters bathrooms, a separate mother-in-law space, a planted rooftop deck, and an urban chicken coop.

Modular madness hits Seattle: mother nature network

A super-efficient, three-bedroom prefab home in Seattle installed in only 6 hours as an urban infill project is on track for LEED Platinum certification. A remarkable, super green prefab home recently installed in Seattle has been making waves throughout the Pacific Northwest and the green building community. It’s a shame that even though I was in the area at the time for the holiday, I didn’t get the chance to check it out (I was too busy shredding).


Seattle Times

Planted in the middle of narrow South Lane Street in Seattle's Central Area, a 115-foot crane lifted a kitchen module into place on a bare foundation. Five more modules followed, assembled like giant Lego pieces. Within a few hours in early December, a two-story, 1,790-square-foot home took shape. The home's builder, Seattle-based Greenfab, says it's the first modular home in the city to target the highest level of sustainability certification from the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) program. LEED raters have been working alongside Greenfab through the designing and building process, and the official certification is expected two months after the home is finished next month.

Greenfab, developer of well-designed, sustainable homes, just installed six modules in the Jackson Place neighborhood of Seattle for what’s expected to be the city’s first LEED Platinum modular home. The demonstration home is owned by Robert Humble of HyBrid, project architect and general contractor, and will target net-zero energy and Built Green 5-Star certification. When completed, there will be about 1,790 square feet of living space, including three bedrooms, two and three-quarters bathrooms, a planted rooftop deck, and an urban chicken coop. Completion is expected in February 2011 for the home located at 1827 S Lane Street in Seattle.

Seattle Times Local News

rowds gathered Tuesday to watch a house take shape as six modules were craned into place. The house, at 1827 S. Lane St., is the first project by the GreenFab development team. GreenFab is a Seattle-based developer of modular housing. The house is for Rob Humble of HyBrid Architecture, architect on the project, and will be complete in about 45 days. Hybrid Assembly is general contractor. Site excavation began last August, and the demonstration home will be open to the public for a limited time. The 1,790-square-foot, two-level house is made of six modules, three on each level. Modules were delivered by long-haul trucks to the Columbia City Light Rail Station, where they were staged before being trucked two miles to the site to be craned into place.

The Prefab Revolution: How this re-emerging industry will lead to a more sustainable future for our planet, homes and economy

Seattle Home and Lifestyle Magazine: What's the Quality?

A prefab home is equal to-some would argue better than-the quality of a traditional stick-built home. "Modules have to be shipped down the  road and then craned onto the foundation. They need to be strong, and the  quality comes in the strength of the home," explains Johnny Hartsfield, who founded GreenFab, a local development group dedicated to creating sustainable buildings. Unlike manufactured homes, which abide by less stringent Housing and Urban Development (HUD) codes, modular and panelized homes must follow the same local building codes as site-built homes. Plus, because prefab projects are built in a controlled indoor environment, wood and other building materials are never exposed to the elements and are less likely to warp or grow mold.

Frustrated with the state of sustainable, affordable housing in Seattle, designer Johnny Hartsfield quit his job, holed up in his basement, took out a home equity loan and didn’t come up for air until he’d developed a solution.
