Simple to manufacture and easy to assemble, the Quonset Hut is an easily recognizable architectural form.  In 1941, a team of engineers at Quonset Point Naval Air Station in Rhode Island designed the building, hence the name.  With America preparing for the possibility of war, the Navy had approached the George A. Fuller Company to design a prefabricated, portable structure that could be shipped in pieces to faraway military outposts.  The structure had to be able to be set up quickly by untrained personnel and had to serve a variety of purposes.  Reportedly a team of ten could build a typical twenty-foot Quonset hut in one day.

The basic Quonset Hut came with multiple pieces of curved steel ribs for the frame; a one-inch tongue-and-groove plywood floor; wood fiber insulation between an outer shell of corrugated metal and an inner lining of Masonite; plus doors, windows and a chimney.  Demand for the prefabricated structure by the various military branches was high, and the Fuller Company couldn’t build them fast enough.  As a result the Navy let out another contract to the Stran-Steel Company, who improved upon the design and soon took over a bulk of the production.  

By the end of WWII, an estimated 150,000 units had been built around the world.  Designed to serve 86 official uses, two basic sizes were offered: the 20 and the 40.  The 20 measured twenty feet by forty-eight feet, while the 40 (also called the “Elephant Hut”) stood forty feet wide by one-hundred feet long. 

By the end of 1941, other companies began developing their own versions of the Quonset Hut. Some, like the Butler and Cowin Companies, developed Quonset-type structures to sell to the Army or anyone else who wanted to buy them.  Others created hut designs in response to special needs, such as the wooden Pacific Hut (built in Seattle), and the Emkay Hut (built in Boise), which were created to save metal resources.  The heavy-steel Armco Hut was intended for ordnance storage and air raid shelters, and the Jamesway Hut was designed for even quicker assembly in cold Arctic regions.

After World War II, a number of surplus Quonset huts found their way into civilian life for us in both residential and commercial applications.  A few of the companies continued to make and sell versions of the Quonset Hut.  The Stran-Steel Company set up dealers all across the country to promote a variety of uses for the huts including use as a single family home or as an agricultural outbuilding.  However, despite the low cost, some as little as $1.50 a sq. ft., the Quonset Hut never became as popular as stick built structures. 

Immediately after the war, many were used as temporary spaces on college campuses, and a variety of federal agencies such as the Bureau of Reclamation, used the Quonset hut to meet postwar building demands.  However, the Quonset hut quickly fell out of favor. Not only did they remind veterans too much of service life, but the Quonset 20, with just 960 sq.ft. of floor space (a good part of it unusable due to the sloping sides) was too small to serve as a family home, or commercial application.   Reportedly, the Quonset hut did work well for other uses.  Stran-Steel issued a press release in late 1946 which listed 257 adaptations.  Uses included housing at Universities, hay barns for farmers, smaller models for milking sheds and storage,  repair shops, and other small businesses, as well as use as temporary churches and Sunday school space. 

Many Quonset hut’s round shoulders are hidden behind false fronts.  Their exteriors can have horizontal or vertical sheets of metal (depending on the model), and the ends can be clad in just about any material and configured with a variety of doors and windows.  Today scattered across the State you will find just a handful of Quonset huts most being used for agricultural purposes, repair shops and small business shops. Others can be found on our State’s military bases, but these are quickly disappearing.



  1. Thank you!

  2. Quonset huts as you have shown are incredibly useful buildings. To make these buildings energy efficient, foil insulation can be used with great success. The flexibility of the product is great for installation. Due to these huts lightweight design there is very little material to stop heat transfer. Adding a radiant barrier is just like covering the hut with a large shade tree!


    • My grandparents lived in Quanset huts after WWII. They qualified for cooper Park in the city. What a trade off!!!! Not much better. After how many years people are complaining? You would thin the human race, yes there is no other race because biology dictates so the people would learn!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  4. United Nations relief orgs need to be Quonset savvy!

    Question for the site: We have a pile of curved galvanized steel panels, about 28″ X 110″, 30 degrees of curve. Seems to make structure about 32′ wide when semicircle of 6 panels are together.

    The panels bolt along sides, about 3″ overlap 19 bolt holes each side. The ends overlap about 7 inches. No apparent need for bracing or framework, as the panels form stout monoqocue structure when assembled & bolted thru all holes. Cross section of individual panels is nearly a semi-circle, concave from the outside. At both side edge, the metal curls around to nearly another (about 3″ dia.) half- circle, and overlaps with adjacent panel for bolting.

    Can someone identify this design, name the manufacturer? I have not found any markings, except “4663” on a few pieces, maybe the date? I would like to find some more panels for railway museum storage shed we are working on. If new material is still available, please let us know, as well. We have about 110 panels, would like to find a couple dozen more. Partial panels OK, if half length or more.

    We would also like to obtain original style galvanized fastening bolts, 5/16 by 3/4, with rubber gasket in the head. Nuts are 9/16 square, galvanized.

    We are circa 1950’s museum, and prefer to keep one or two buildings in era if possible. Used panels would fit right in. If we can find new, they would be used in upper roof portion, not so visible to ground level. Thank you for help.

  5. In 1963 the 7th Finance Disbursing Section of Vietnam was housed in a Quonset type building as this office was fire proofed due to the contents
    We are trying to find out what the black sheets were that we painted if any one knows please advise or if you know of any person or archive that might contain this information PLEASE Advise.
