Post-World War II Prefabricated Aluminum and Steel Houses and Their Relevance Today

Peter Lobner

With the decline of military aircraft production after World War II (WWII), the U.S. aircraft industry sought other opportunities for employing their aluminum, steel and plastics fabrication experience in the post-war economy. In the 2 September 1946 issue of Aviation News magazine, there was an article entitled “Aircraft Industry Will Make Aluminum Houses for Veterans,” that reported the following:

“Two and a half dozen aircraft manufacturers are expected soon to participate in the government’s prefabricated housing program.”

“Aircraft companies will concentrate on FHA approved designs in aluminum and its combination with plywood and insulation, while other companies will build prefabs in steel and other materials. Designs will be furnished to the manufacturers.”

“Nearly all war-surplus aluminum sheet has been used up for roofing and siding in urgent building projects; practically none remains for the prefab program. Civilian Production Administration has received from FHA specification for aluminum sheet and other materials to be manufactured. ….Most aluminum sheet for prefabs will be 12 to 20 gauge – .019 – .051 inch.”

Under the government program, the prefab home manufacturers were protected financially with FHA guarantees to cover 90% of costs, including a promise by Reconstruction Finance Corporation (RFC) to purchase any homes not sold. In addition, these manufacturers were to be given preferred access to surplus wartime factories that could be converted for mass-production of homes.

The business case for the post-war aluminum and steel pre-fabricated homes was that they could be sold profitably at a price that was substantially less than conventional wood-constructed homes.

Not surprisingly, building contractors were against this program to mass-produce pre-fabricated homes in factories. Moreover, local building codes and zoning ordnances were not necessarily compatible with the planned large scale deployment of mass-produced, prefabricated homes.

Now consider the most common housing problem of today, which seems to me to be a shortage of available low-cost housing. In recent years, this has sparked the “tiny home movement,” which is a social and architectural movement promoting living simply in small homes. Seventy years after the end of WW II, it may be time to reconsider the use of mass-produced, prefabricated aluminum and steel homes to address the current shortage of low-cost housing.

Let’s take a look at several of these efficient, and sometimes stylish post-war prefabricated homes:

  • Beech Aircraft’s aluminum Dymaxion house
  • Consolidated Vultee’s aluminum Fleet house
  • Lustron’s steel houses
  • Lincoln Houses Corporation’s aluminum houses
  • Alcoa’s mid-century modern aluminum Care-free houses
  • UK’s AIROH aluminum houses
  • UK’s Arcon steel-framed houses
  • French architect Jean Prouvé’s “Demountable house”

Beech Aircraft Corporation planned to mass-produce R. Buckminster Fuller’s Dymaxion house

In 1927, R. Buckminster Fuller developed plans for the Dymaxion (acronym for “dynamic, maximum, tension”) house, which was intended to be a mass-produced metal house of novel circular design.

Early interest in applying aircraft aluminum manufacturing techniques to post WWII housing construction was expressed by Beech Aircraft Corp. In 1944, Beech established a joint project with Dymaxion Dwelling Machines, Inc. (later renamed Fuller Houses, Inc.) to manufacture a prototype, updated Dymaxion house in Wichita, Kansas. The strong aluminum riveted structure and skin was built from WWII surplus material, with the aluminum-domed roof hung from a stainless steel strut; providing 1,017 ft2 of floor space. The aluminum, stainless steel and plastic house weighted about 8,000 pounds and was designed to withstand severe weather, including tornados.

The 1 April 1946 issue of Aviation News magazine reported:

“Beech Aircraft Corp. expected to build 200 of these houses a day soon after the start of 1947, according to Herman Wolf, president of Fuller Homes, Inc., which will market the dwelling designed by R. Buckminster Fuller……..The houses will be subcontracted to construction firms which will combine aircraft technology and auto mass production methods. Wolf and Fuller see the new dwellings, which will sell for $6,500 erected, as the answer to the veterans housing problem. City building codes are the big imponderable in forecasting the success of this dwelling.”

Only two Dymaxion houses were built. One is now in the Henry Ford Museum in Dearborn, Michigan.

Consolidated Vultee Aircraft Corporation built the Fleet House

The California aircraft manufacturer Consolidated Vultee (later Convair) considered mass-producing a pre-fabricated homes for the post-WWII housing market. Collaboration with industrial designer Henry Dreyfuss and architect Edward Larrabee in 1947 led to the design of a small two-bedroom home. With kitchen appliances, kitchen and bathroom fixtures, and heating, the house was expected to sell for $7,000 – $8,000, including the cost of the lot.

Only two prototypes were manufactured in 1947.

An article by Jeffrey Head entitled “Snatched from Oblivion,” on the Metropolis website reported:

“Comprising 28 parts, the two-bedroom, one-bath structure appears larger than its 810 square feet because 75 percent of the exterior walls are windows. The remaining interior, roof, and garage walls are constructed of “lumicomb,” a lightweight material made of a cardboard-like honeycomb core bonded between sheets of high-strength aluminum, used at the time for airplane bulkheads. The lumicomb adds to the open feeling of the house by requiring less floor space than traditional wall and roof construction.”

“Because the resulting design was so unorthodox, Reginald Fleet, president of Southern California Homes Incorporated, opted for a novel way of marketing it. Fleet resided in the prototype with his wife and daughter, leaving it open for prospective buyers to see what life was like in a modern prefabricated home.”

“New owner Sergio Santino was about to close escrow and planned to raze the house until the South Pasadena Cultural Heritage Commission informed him of its significance.”

Here it is noted:

“Historically known as the “Consolidated Vultee House”, and commonly referred to as “the Fleet House”, today it may be the only structure still remaining that was designed, built and pre-assembled entirely in an aircraft factory.”

“The Fleet House is featured in Taschen’s PREFAB HOUSES 2010.  It is referenced in numerous publications documenting the history of pre-fab housing and has been photographed by noted post WWII architectural photographer Julius Shulman.”

Lustron Corporation offered low-maintenance steel homes

The Lustron Corporation, formed in 1947 by Carl Strandlund, received financing from RFC to mass-produce steel pre-fabricated houses in a former Curtiss-Wright aircraft factory in Columbus, OH.

Lustron homes came in 2- and 3-bedroom models ranging in size from 713 ft2 to 1,140 ft2. All homes came standard with enamel-coated steel exterior panels, enamel-coated steel shingle roof, metal ceiling tiles and metal-paneled interior walls, metal cabinets, closets with pocket doors, and service and storage areas.

Below is a 1949 photo of the prefabricated components of a Lustron house.

Original plans were to manufacture more than 10,000 homes per year. Actual production was much less, with a total of 2,498 Lustron homes manufactured between 1948 and 1950. House prices were in the $8,500 – $9,500 range, increasing to an average of about $10,500 by the end of 1949. This was approaching the price of a comparable, conventional, wood-constructed house.

The Lustron Corporation declared bankruptcy in 1950. The business failed because of several factors, including production delays, poor distribution strategy, and escalating prices that reduced the price advantage of a pre-fabricated house.

About 2,000 Lustron homes still exist today. You can read more on Lustron houses at the following link:

Lincoln Houses Corp. offered 2- and 3-bedroom aluminum homes

During WWII, Lincoln Industries developed processes for making structural material at low cost for radar housings. This process led to the design of 4’ x 8’ structural panels for buildings that were manufactured using the following process:

“Lincoln plastic panels are made by alternating sheets of heavy paper, cloth, or glass cloth with glue strips. When the desired thickness is obtained, the sheets are expanded on an automatic machine to form a honeycomb pattern. This honeycomb core is thoroughly impregnated with high-strength phenolic resin and then bonded between facing sheets of aluminum alloy, and the entire panel sealed with a vapor barrier.”

This material provides both great strength and high insulating properties. The bearing capacity of a two-inch thick wall panel compared favorably with the load carrying capacity of a brick wall one foot thick. The three-inch thick roof panels were designed to withstand an eight-foot snow load.

The basic house contained two bedrooms, a bath, living room, kitchen, dining room and general utility room. Under the Veteran’s Emergency Housing Program, the Lincoln pilot plant in Marion, Virginia manufactured and sold 2-bedroom homes for about $3,500 – $4,000 and a 3-bedroom home for about $4,500, including, “wiring, water piping and heating,” constructed on a concrete or similar slab. These prices did not include the price of the land or the price of kitchen appliances and a hot water heater. Construction took about two days.

The house was designed for severe weather and the materials of construction provided protection against dry rot, internal condensation and termites.

By 1946, numerous Lincoln aluminum homes had been built and were in use. However, it appears that Lincoln never made the transition to large scale production in former airplane factories.

Aluminum Company of America (Alcoa) offered mid-century modern aluminum Care-Free Homes

After WWII, aluminum manufacturers were faced with large stocks of aluminum ore and decreasing orders. Like the aircraft manufacturers, Alcoa sough alternate markets for their finished aluminum products.

A decade after the end of WWII, Alcoa offered the Care-Free Home, which was a mid-century modern aluminum ranch house designed by Charles M. Goodman. Originally, Alcoa planned to build one Care-Free home in each of the 48 states to showcase the versatility of aluminum in home construction. A total of 24 Care-Free homes were built. The house has a 1,900 ft2 living area, a full basement, and a 2-car carport.

The framing is aluminum and wooden columns are clad in aluminum. The exterior is aluminum siding with big, aluminum-framed windows and sliding doors, and an aluminum front door. The roof and fascia strip also are aluminum. The originally expected price was about $25,000, but actual cost was almost double. In the mid-1950s, the Care-Free house couldn’t compete with the lower cost of conventional wood construction.

Post-war prefabricated aluminum and steel homes in the UK

In 1944, the UK Ministry of Works held a public display at the Tate Gallery in London of five types of prefabricated homes.

  • One aluminum prefab, made from surplus aircraft materials, the AIROH (Aircraft Industries Research Organization on Housing)
  • One steel-framed prefab with asbestos panels, the Arcon, which was adapted from the all-steel Portal prototype
  • Two timber-framed prefab designs, the Tarran and the Uni-Seco

This popular display was held again in 1945.

In comparison to the very small number of post-war aluminum and steel prefabricated homes built in the U.S., the production in the UK was very successful.

The AIROH aluminum house

An pre-fab package for an AIROH house consisted of 2,000 components that were assembled in four sections and delivered to the intended site by truck. The fully equipped bungalow weighed about 10 tons and provided 675 ft2 of living space, including a fully equipped kitchen and bath. In 1947 an AIROH home cost £1,610 ($6,488 @ $4.03 USD/£ in 1947) each to produce, plus cost of the land and installation. A total of 54,500 AIROH homes were constructed.

The Arcon steel-framed house

The steel-framed Arcon prefabricated home had two bedrooms, fully equipped kitchen and bath and included steel built-in cabinets in the kitchen, bath and bedrooms. Exterior walls and roofing were made of corrugated asbestos panels. The house was manufactured in four 7ft-6in wide sections to enable road transportation to a pre-prepared site where the house was assembled. An Arcon house cost £1,209 ($4,872 U.S. @ $4.03 USD/£ in 1947) each to produce, plus cost of the land and installation. A total of 38,859 Arcon homes were constructed.

Post-war prefabricated metal frame homes in France

A notable French design was Jean Prouvé’s “Demountable House,” which was developed in 1946 under a commission from the Ministry of Reconstruction and Town Planning for use as temporary bungalows for post-war housing for Lorraine, France. The metal frame load-bearing structure of the Demountable House is shown in the first photo below. Panels of various types are then attached to the frame to complete the exterior of the house and any internal room partitions.

To demonstrate the ease with which Prouvé’s pre-fabricated house can be assembled on site, one model was built and then taken apart every day during Art Basel Miami 2013.

In conclusion

In the U.S., the post-war mass production of prefabricated aluminum and steel houses never materialized. Lustron was the largest manufacturer with 2,498 houses. In the UK, over 93,000 prefabricated aluminum and steel houses were built as part of the post-war building boom that delivered a total of 156,623 prefabricated houses of all types between 1945 and 1951, when the program ended.

The lack of success in the U.S. arose from several factors, including:

  • High up-front cost to establish a mass-production line for prefabricated housing, even in a big, surplus wartime factory that was available to the manufacturer on good financial terms.
  • Immature supply chain to support factory operations.
  • Ineffective distribution and delivery infrastructure.
  • Unprepared local building codes and zoning ordnances.
  • Opposition from construction workers and unions that did not want to lose work to factory-produced homes.
  • Manufacturing cost increases, which reduced or eliminated the price advantage of the prefabricated homes.

From these post-war lessons learned, and with the renewed interest in “tiny homes”, it seems that there should be a business case for a modern, scalable, smart factory for the low-cost mass-production of durable prefabricated houses manufactured from aluminum, steel, and/or other materials. These prefabricated houses should be modestly-sized, modern, attractive, and customizable to a degree while respecting a basic standard design. These houses should be designed for siting on small lots in urban or suburban areas and for rapid construction.

The UK post-WWII prefab housing boom lasted seven years and delivered low-cost housing for about a half million people. I believe that there is a large market in the U.S. for this type of low-price housing, but great obstacles must be overcome, especially in California, where nobody will want a modest prefabricated home sited next to their McMansion.
