The world of prefab and modular homes. |

MoMA's Home Delivery show opens a week from tomorrow so it's been getting a lot of attention around the web.
The New York Times added a little article blurb to the slideshow they posted the other day:
Even by New York City standards, it’s quite a sight. On a 17,000-square-foot vacant lot just west of the Museum of Modern Art, a mini-suburb of contemporary houses is being built — practically overnight.
Lloyd Alter of Treehugger wrote a series of posts on the exhibition:
- Monday: the Digitally Fabricated House
-
Tuesday: the
BURST*008
-
Wednesday: the System3 house
-
Thursday: the micro compact home
- Friday: the Cellophane House
HAUTE*NATURE took a green perspective.
We'll let Inhabitat's Prefab Friday have the last word:
get down to the MOMA to take in this fantastic prefab extravaganza.
This last week has seen some impressive progress in the installation of homes for MoMA's Home Delivery exhibition, opening July 20.
In the video above, the System3 home hatches from its shipping containers and is craned onto its temporary foundation in midtown Manhattan. The bones of the BURST*008 model can also be seen in the video, from about 0:10 to 0:25.

I wrote about Oskar Leo Kaufmann and Albert Rüf's System3 last week. It will be included in The Museum of Modern Art's Home Delivery exhibition.
The two designers have been working in the prefab arena since 1996. Past models include:
• System 01 and System 02 based on "elements"
• Su-Si, Fred, Houses A&B based on "units"
The System3 home merges the idea of "units" with that of "elements":
Due to the separation into serving units and "naked elements", the building process is optimized.
The serving unit is a completely prefabricated box including all installations. All different trades, such as electrician, plumber, etc. do their work at the service unit factory and do not have to do any on-site work....
The solid elements such as wall, floor, and ceiling are made of solid slabs of wood. The producer uses CNC-technology to cut out all openings.
...the window producer prefabricates all windows.
...the skin producer prefabricates the building's skin that includes thermal insulation, waterproofing and vapor barrier.
To me, it seems logical: keep the production of the technical pieces, the "serving units", in the factory where quality control can be tighter; let on-site work be limited to assembly and nothing more. This approach would save both time and money, limiting the trades and expertise needed at the home site; it reminds me of KieranTimberlake's Loblolly House, which we covered last June:
The assembly process begins with off-site fabricated floor and ceiling panels, termed 'smart cartridges.' They distribute radiant heating, hot and cold water, waste water, ventilation, and electricity through the house. Fully integrated bathroom and mechanical room modules are lifted into position. Exterior wall panels containing structure, insulation, windows, interior finishes and the exterior wood rain screen complete the cladding.(KieranTimberlake's Cellophane House will also appear in the MoMA show.)
Such a mixed-method approach compares to the two major types of prefabrication that we cover on Prefabcosm: SIPs (used by companies like CleverHomes and Jensys Buildings) and complete modules (like those from OMD and weeHouse). Using just SIPs leaves the majority of the skilled work for the site, e.g. installation of utilities. Complete modules are both expensive and difficult to get to the home site. Merging the two methods allows for greater flexibility, less cost, higher quality, and shortened construction time.
With 10+ years working on prefab, Oskar Leo Kaufmann and Albert Rüf are worth watching. While they have yet to translate their experiments into a mass-market product, their work lends much understanding to how the home-construction industry might best take advantage of prefabrication.

System3, from Austrian designers Oskar Leo Kaufmann and Albert Rüf, will also be showcased in MoMA's Home Delivery: Fabricating the Modern Dwellings show:
The system is based on the separation of a building into "serving space" and "naked space".The "serving space" is a completely prefabricated serving unit that provides all staircases, kitchens, baths, installations, electricity, heating, and cooling systems for the entire building. The "naked space" (space that is only defined by the placed furniture, such as living or sleeping rooms) is formed by "naked elements": solid slabs of wood...windows, skin. All "naked" elements are also prefabricated and are delivered directly from factory to building site, where everything can be assembled in a few days.
Each unit fits in a shipping container, giving it the characteristic "long and narrow" format. Several units can be placed side by side:
Or stacked:
Overall, an intriguing approach that I can't wait to see realized at MoMA. Oskar Leo Kaufmann and Albert Rüf have been experimenting with prefab since 1996. We'll look at their past work in more depth soon!
