The Christian Science Monitor took a look at modular homes last week, focusing on the green qualities:

This summer, two exhibitions of modular houses – at Chicago’s Museum of Science and Industry (MSI) and New York’s Museum of Modern Art (MoMA) – are putting a spotlight on how off-site building techniques can shrink the carbon footprint of a new house.

The article cites a number of reasons why building in the factory is a good idea:

• finish construction usually takes a few weeks, not months, saving energy by requiring fewer trips to the job site by construction workers
• by building indoors, workers can also more easily make sure that energy-saving features like insulation are carefully and properly installed for maximum effectiveness
• individual home-building companies may not have the resources to keep current on the latest "high-performance building" techniques ... but modular homes can have state-of-the-art environmental design built into them at the factory

The companies mentioned in the article:

• KieranTimberlake Associates
• Michelle Kaufmann Designs
• HOM Escape in Style
• Envision Prefab
• Cardinal Homes

We missed this item last year when we covered West Coast Green 2007: the EPA's Lifecycle Building Challenge. From a West Coast Green email:

... a design competition for students and professionals focusing solely on innovation regarding deconstruction and building material reuse.

And the Lifecycle Building Challenge was born! Submissions from architects, students, planners and builders poured in, ranging from de-nailer guns to radio-tagged, re-useable wall panels to design that considers reuse as it's primary function.

The awards were presented last year at West Coast Green.

The Challenge returns to this year's show. The ability to take apart a building and re-assemble it elsewhere seems like prefab in its purest form.

I missed last week, so here is two weeks of prefab news. Daily posts will resume this week; sorry for the gaps!

Jetson Green links to a student prefab project at Taliesin West:

The students, with Dean Victor Sidy and Jennifer Siegal of OMD, designed a simple but elegant home with sustainability in mind. At first, they were going to prefabricate the structure, but later decided to go instead with on-site, panelized construction using SIPs for the walls, roof, and floor.

Last week, Inhabitat's Prefab Friday discussed a unique idea for Olympic stadiums:

Currently there are plans in place to dismantle around 70% of the proposed London Olympic Stadium, pack up the components, and send them to the host of the 2016 Olympics!

Yesterday, Prefab Friday covered the Joshua Tree house that we've seen previously:

This steel clad prefab is a compact two bedroom “mountain refuge” with a welcoming, and surprisingly roomy, wooden interior.

Two weeks ago, Inhabitat looked at a container home in New Zealand.

LLoyd Alter, of Treehugger, wrote about green prefab at the Huffington Post:

They are everywhere in all the magazines: "Green" modern prefabs. But are they really green?

Treehugger visited the mkSolaire at Chicago's Museum of Science and Industry:

The Smart Home has been outfitted with some of the most sustainable and responsible options available for building and furnishing a house, while the landscaping illustrates many ways to sustain and replenish the surrounding environments we live in. It’s really spectacular to see the museum’s courtyard transformed in this way.

Finally, Dwell on Design started yesterday. We'll have a full review of happenings at the show this coming week.

The Denver Post reports on a modular homeowner near Denver:

Jill Warner is having a new home built in Salida that's as green as possible without "going overboard," she said.

...

Warner wanted to buy a prefab home from the beginning, but her early research revealed a stiff price tag — about $320 per square foot using an out-of-state builder.

Then she dug deeper and found companies closer to home. That cut the price by more than half.

Warner found Northstar Homes, based in Loveland, Colorado. According to Hollis Hunt of Northstar:

...people incorrectly assume going green means a sizable price tag. He says homebuyers can make choices that won't break the bank.

Their site features some helpful resources, including a list of modular home myths.

Read the full article for other tips on how to build prefab and meet your budget. The article also updates readers on the MKD development in Denver that we've reported on previously.

Coming soon to green living shows in Yorkdale, Canada (June 5-15) and Toronto (September 25-26), the Canühome is an example of cutting-edge eco-friendly home design. The Canühome website explains:

The 850 sq.ft. exhibition contains a kitchen, living room, dining room, bathroom and bedroom.

The exhibit includes interpretive panels which highlight the features of the design for the public...

Why is this exhibition so helpful? Ecolectic sums it up:

Made largely of FSC certified plywood and other wood materials, the modular home is assembled with the aid of steel brackets. Being modular you can hook up as many or as few units as you like should your need for space grow or diminish. The engineering behind the design is quite ingenious. Its shape allows for convective and radiant heating, and they proudly announce that "air is a building material"!

And Toronto's Globe and Mail newspaper goes into further detail:

...canühome's most intriguing feature is its passive solar "double envelope." Air passing between the two exterior walls on the south side is heated via the dark metal panels of the outermost skin. This heated air travels up and is vented out of the top in summer but, in winter, continues around the other side and into the radiant floor, which keeps the house about 10 degrees [50F]....

Canühome's "breakthrough" was the invention of a new fastener called a "Porcupine." These attach to the wooden structural ribs, extend outward to create the air gap and terminate where the outermost metal panels clip on. Not only is this method much cheaper, it's flexible.

Treehugger likes the idea:

...the designers have used the latest CNC technology and a lot of other ideas that make it one of the more interesting test beds we have seen.

The Marmol Radziner Prefab blog wrote about the installation of a new home in California. Check out the post for pictures, including the vibrant blue denim insulation seen above.

greenbuildingsNYC discussed Modular Homes, Inc.:

...an Edison, New Jersey-based custom modular home builder that will break ground in April on what it hopes will be a LEED-certified model home in Robbinsville, New Jersey....

Inhabitat's Prefab Friday covered the ABŌD affordable prefab we saw last week.

The Good Human's Prefab Wednesday took the week off.

Inhabitat's Prefab Friday looked at a Swiss prefab that uses straw bales:

We’re quite taken by Strohhaus in Eschenz, Switzerland. Designed by Zurich-based architect Felix Jerusalem, this home masterfully combines prefab with sustainable materials, primarily prefabricated strawboard panels that provide affordable, environmentally sound insulation.

Jetson Green covered GreenMobile, an "ultra-affordable, modular green [manufactured] home":

GreenMobile was awarded $5.8 M from FEMA to further develop the prototype and roughly 80 units are in the pipeline right after that prototype comes through.

GreenMobile is expected to cost about $50k

100khouse likes the 'Option' House, covered on Prefab Friday a couple weeks back.

The Michelle Kaufmann blog announces:

...we have been working very hard for the past few months to get to this point and are now finally ready and delighted to announce that MKD is going to be a part of the “Smart Home: Green + Wired, Powered by ComEd and Warmed by Peoples Gas” exhibit at MSI that’s opening this spring! The exhibit is going to include a full-size mkSolaire™ home to be built in on parkland on the southeast side of the Museum and will showcase the very best in sustainable living concepts and solutions.

A bit more from the museum exhibit page:

During its 75th Anniversary year, the Museum of Science and Industry will be building a functioning, three-story modular and sustainable “green” home ... to highlight unique home technologies for the 21st century.

The Greater Fort Wayne [Illinois] Business Weekly quotes Art Breitenstein of the home's builder, All American Homes:

The home’s module construction will be under way for two or three more weeks on one of the All American assembly lines in Decatur....

“This is a special house, a very high-priced house; it has the best of the best. ... there’s a lot of new technology in there that’s one-of-a-kind that if it becomes accepted by consumers, like anything else, the price comes down of course.”

Jetson Green says:

I can't wait to see more!

I wandered over to the XtremeHomes site the other day and found that they are now writing a blog:

A brief collection of thoughts on the growth of the green building industry. What's real, what's not and what people are expecting.

Definitely worth keeping an eye on.

company: XtremeHomes

Systm, a web video series from Revision3, files a long, detailed video report from the WIRED LivingHome:

This $4 million home in LA isn't exactly what we think of when wanting to integrate more green, eco-friendly aspects to our lives, but it does offer up some great options. LEED certified and designed by architect Ray Kappe, this home offers a great, simple way of constructing a house without compromising the uniqueness of a custom built home.

The m-ch (micro compact home) will also be included in the upcoming MoMA prefab exhibition.

The New York Times says:

Mr. Horden’s Micro Compact House — Mr. Bergdoll [of MoMA] described it as “a giant livable Sony radio cube” — is topped with photovoltaic panels and has wind turbines in its walls, allowing the house to generate its own electricity. An aluminum-clad perfect cube, with about 76 square feet of living space, the tiny dwelling is intended for use as athletic or student housing, or as a miniature vacation house. Mr. Bergdoll met with Mr. Horden in one of his cubes, a space so compact that the architect managed to make espresso on the kitchen counter without leaving his seat at the dining table.

The house is commercially available — it recently went on the market in Europe — and can be delivered by helicopter or crane.

From the micro compact home site:

The micro compact home [m-ch] is a lightweight compact dwelling for one or two people. Its compact dimensions of 2.6m [8.5 ft] cube adapt it to a variety of sites and circumstances, and its functioning spaces of sleeping, working / dining, cooking and hygiene make it suitable for everyday use.

Informed by aviation and automotive design and manufactured at the micro compact home production centre in Austria, the m-ch can be delivered throughout Europe with project individual graphics and interior finishes.

The team of researchers and designers based in London and at the Technical University in Munich developed the m-ch as an answer to an increasing demand for short stay living for students, business people, sports and leisure use and for weekenders. The m-ch, now in use and available throughout Europe, combines techniques for high quality compact 'living' spaces deployed in aircraft, yachts, cars, and micro apartments. Its design has been informed by the classic scale and order of a Japanese tea-house, combined with advanced concepts and technologies. Living in an m-ch means focusing on the essential - less is more. The use of progressive materials complements the sleek design. Quality of design, touch and use are the key objectives for the micro compact home team....for 'short stay smart living'.

The specifics:

The m-ch has a timber frame structure with anodised aluminium external cladding, insulated with polyurethane and fitted with aluminium frame double glazed windows and front door with security double lock; graphics can be applied for sponsors, exhibition and business use.

• two compact double beds...
• storage space for bedding and cleaning equipment
• a sliding table ... for dining for up to five people
• flat screen television in the living/dining space
• a shower and toilet cubicle
• a kitchen area, which is fitted with electrical points and features a double hob, sink and extending tap, microwave, fridge and freezer units, three compartment waste unit, storage shelves, cutlery drawers with gentle return sprung slides and double level work surfaces
• thermostat controlled ducted warm air heating, air conditioning, water heating
• fire alarm and smoke detectors

m-ch units are available to purchase for delivery to geographical Europe at a guide price of EUR 25,000 to EUR 34,000 (subject to contract).

More images of the interior:

We've mentioned the home before in our This Week series. Back in June, we also linked to a video of the m-ch.

Banks.com loves weeHouses and the new weeHouse site:

I like weeHouses for three reasons:

1. They look cool, and what’s not to love about that boxy Frank Lloyd Wright style?

2. They are eco-friendly....

3. These houses are smaller and more streamlined, yet still appear functional....

The Good Human's Prefab Wednesday covered an Australian prefab home, called The Mod House from Prebuilt. We'll look at that company in more detail soon.

Inhabitat's Prefab Friday got excited about a gingerbread version of the mkLotus:

The only thing better than beautifully designed green prefab is edible green prefab! One of our favorite green architects Michelle Kauffman, in honor of the holiday season, has designed a yummy version of her awesome zero energy mkLotus, made entirely from gingerbread cookies...

Treehugger, Curbed San Francisco, and re-nest also enjoyed the holiday version of prefab.

The Good Human's Prefab Wednesday discussed the Zenkaya prefab home from South Africa:

the home can be delivered in as little as 5 weeks.... [It comes] completely assembled, and all the owner would have to do is hook up the electric, the water and the sewer, and their home is ready to go.

Inhabitat's Prefab Friday covered the PowerHouse homes:

Our favorite, the “solar butterfly” roof design, collects rainwater, maximizes the use of daylight, and is fitted with solar photovoltaic panels to generate electricity - all for about $100,000!

Materialicio.us found a prefab kit called the casa ti, not yet in production:

The structure is framed in high-recycled-content steel, in SIP form. You can buy casa ti in kit form or buy the plans to build it from scratch. Prices for the kit start at $20,000.

Architecture.MNP showed off the BaleHouse, which uses straw bales for walls.

Treehugger looks back: Three Years Ago In TreeHugger: Prefab Crazy.

The Good Human's Prefab Wednesday discovered the zeroHouse:

Holy Moly Batman…a house that powers itself, composts its own waste, collects its own water, and is completely automatic doing all of these things. When can I get one?

Inhabitat's Prefab Friday wrote about the Linx Shipping Container Shelter, a container concept from Ireland:

Using 20-foot shipping containers, Barnwall’s idea provides functional shelter for workers on a construction site offering all the amenities needed to give workers a comfortable place for pause.

Treehugger covered the Loq•kit prefab concept which we covered last week:

It is an ingenious and very well resolved idea for revolutionizing the way we build houses, breaking it down into components that snap together much like an office system.

Materialicio.us also discussed the home, with commentary by Greg La Vardera:

I think it is tremendously clever, and has the characteristics of a truly disruptive technology. It has the potential to change radically the way we build houses.

Curbed LA released an update on the reduced price of the Resolution: 4 vacant lots in LA:

...now the lots, which come with plans to build, are listed at $295,000 and $275,000

From earlier this week:

Google...announced a new strategic initiative to develop electricity from renewable energy sources that will be cheaper than electricity produced from coal. The newly created initiative, known as RE<C, will focus initially on advanced solar thermal power, wind power technologies, enhanced geothermal systems and other potential breakthrough technologies.

Many prefab companies incorporate solar power and other environmentally friendly features into their housing solutions. eSolar (a Google partner) incorporate prefab features into their solar solutions:

By leveraging established commercial suppliers to mass manufacture thousands of small heliostats, eSolar realizes economy-of-scale benefits at much smaller power plant sizes than traditional solar generation techniques. Our heliostats are designed to fit efficiently into shipping containers to keep transportation costs low, and they are pre-assembled at the factory to minimize on-site labor....

By employing a repeating frame structure and a revolutionary calibration system, eSolar has eliminated the need for high-precision surveying, delicate installation, and individual alignment of mirrors. Minimal skilled labor is needed to build the solar field, allowing for mirror deployment efficiencies that scale with project size and deadlines.

Very interesting: prefab meet solar; solar meet prefab.

Michelle Kaufmann's mkLoft will be used in a new development in Denver. From the Rocky Mountain News:

Denver developers Susan Powers and Chuck Perry are teaming with Kaufmann to put 40 factory-built town houses on 21 acres near Regis University at West 52nd Avenue and Federal Boulevard. The 1,100- to 1,500-square-foot town houses will be built at the All American Homes factory in Milliken, in Weld County, and trucked 60 miles, in sections, to the Denver site for assembly.

That they're modular won't be apparent, as factory-built houses don't necessarily have the mass- produced, cookie-cutter look they did 30 years ago.

Read more about the plans in the full article.

The gadget blogs have taken a liking to the Zero House. From Yanko Design:

ZeroHouse is a great concept and for added enjoyment, can be customized with a variety of color and material combinations.

Gizmodo is a fan:

Not only is this Zero House by architect Scott Specht completely green, automatic and self-sufficient, but it looks so badass it could've come out of the movie Clockwork Orange.

CrunchGear also covered the home.

Jetson Green reported on La Maison de Demain, a french prefab concept:

The home is built with three prefabricated modules and is meant to show that green design can be affordable and attractive. An important aspect of the house is the open area in the middle, which could be used as a covered patio to extend the footprint of the home into the natural environment.

The Good Human's Prefab Wednesday appears to be on an extended hiatus?

Inhabitat's Prefab Friday covered OMD's Country School:

The Los Angeles middle school expansion project opens next month to some very lucky kids who will enjoy classrooms filled with light, open learning spaces, and the best and healthiest materials. We’re big fans of Jennifer and her Office of Mobile Design here at Inhabitat, and we’re thrilled that her great prefab designs are being successfully applied to educational contexts- what better way to learn and teach than in a wonderful healthy classroom?

Many blogs reported on the end of DoResearch, a blog that collected information on a couple's favorite prefabs. Materialicio.us said

If it’s any consolation, they’ve found some land and they’re planning to build a FlatPak on it in Spring ‘08.

The Prefab Dweller is enthusiastic about the ZeroHouse:

The Zerohouse sure fits both my dreams...

Michelle Kaufmann Designs is one of the hottest companies in the modernist prefab world today. Right on the heels of the mkLotus comes the announcement of the mkLoft:

This spacious 2-story, 2-bedroom + loft features a double-high ceiling in the living room, creating an open, harmonious environment for reflection and creativity.

mkLoft™ is the perfect design for urban dwelling, whether you are looking to build your primary residence or live/work solution, a duplex, or a healthy community, this home can be designed in 2- or 3-story configurations to suit your needs....

mkLoft™ is also ideal in a multifamily development layout.

The Good Human was impressed:

She has done it again - come out with another stunning example of what a modern prefab can be.

Inhabitat noted the low price of the homes:

Depending on volume and finishes, the typical mkLoft ranges from $130 to $140/sf. This does not include the cost of land nor the permit approval process.

We first announced the WIRED LivingHome back in July. The modules were installed in September.

And now: tours! From the WIRED blog:

Want to visit? The  Wired LivingHome is open to the public Thursday through Sunday until Nov. 19.

For ticket purchasing info and additional tour details, visit the WIRED LivingHome site.

The Good Human's Prefab Wednesday took a break this week.

Inhabitat wrote about the ASAP House, which we will cover in more depth soon.

Bannaga covered a boathouse with a prefab steel structure that recently won an architecture award in Texas.

The blog also previewed a prefab concept called the Zero House:

ZeroHouse is a 650-square-foot prefabricated house designed to operate autonomously, with no need for utilities or waste connections. It generates its own electrical power, collects and stores rainwater, and processes all waste. Shipped to a site on two flatbed trailers, it can be field-erected in less than a day.

The St. Louis Business Journal discusses EcoUrban:

Last week CNET released a video report from the mkLotus (3:13). This follows last month's visit to the XtremeHomes factory.

The video features some interior views of the house and an interview with Rebecca Woelke, who's in charge of PR for Michelle Kaufmann Designs.

I learn new things about the prefab business every day. Altamont Homes is a builder of modular homes throughout the West. The compa
