Shipping container architecture

Shipping container architecture is a form of architecture using steel intermodal containers (shipping containers) as structural element, because of their inherent strength, wide availability and relatively low expense.

Advantages

Strength and durability

Shipping containers are in many ways an ideal building material. They are designed to carry heavy loads and to be stacked in high columns. They are also designed to resist harsh environments, such as on ocean-going vessels or sprayed with road salt while transported on roads. Due to their high strength, containers are useful for secure storage.

Modular

All shipping containers are made to standard measurements and as such they provide modular elements that can be combined into larger structures. This simplifies design, planning and transport. As they are already designed to interlock for ease of mobility during transportation, structural construction is completed by simply emplacing them. Due to the containers' modular design additional construction is as easy as stacking more containers. They can be stacked up to 12 high when empty.

Labor

The welding and cutting of steel is considered to be specialized labor and can increase construction expenses, yet overall it is still lower than conventional construction. Unlike wood frame construction, attachments must be welded or drilled to the outer skin, which is more time consuming and requires different job site equipment.

Transport

Pre-fabricated modules can also be easily transported by ship, truck or rail, because they already conform to standard shipping sizes.

Availability

Used shipping containers are available across the globe.

Expense

Many used containers are available at an amount that is low compared to a finished structure built by other labor-intensive means such as bricks and mortar — which also require larger more expensive foundations. Construction involves very little labor and used shipping containers requiring only simple modification can be purchased from major transport companies for as little as US $1,200 each. Even when purchased brand new they are seldom more than US $6000.

Disadvantages

Temperature

Steel conducts heat very well; containers used for human occupancy in an environment with extreme temperature variations will normally have to be better insulated than most brick, block or wood structures.

Humidity

As noted above, single wall steel conducts heat. In temperate climates, moist interior air condenses against the steel, becoming clammy. Rust will form unless the steel is well sealed and insulated.

Construction site

The size and weight of the containers will, in most cases, require them to be placed by a crane or forklift. Traditional brick, block and lumber construction materials can often be moved by hand, even to upper stories.

Building permits

The use of steel for construction, while prevalent in industrial construction, is not widely used for residential structures. Obtaining building permits may be troublesome in some regions due to municipalities not having seen this application before.

Treatment of timber floors

To meet Australian government quarantine requirements most container floors when manufactured are treated with insecticides containing copper (23–25%), chromium (38–45%) and arsenic (30–37%). Before human habitation, floors should be removed and safely disposed. Units with steel floors would be preferable, if available.

Cargo spillages

A container can carry a wide variety of cargo during its working life. Spillages or contamination may have occurred on the inside surfaces and will have to be cleaned before habitation. Ideally all internal surfaces should be abrasive blasted to bare metal, and re-painted with a nontoxic paint system.

Solvents

Solvents released from paint and sealants used in manufacture might be harmful.

Damage

While in service, containers are damaged by friction, handling collisions, and force of heavy loads overhead during ship transits. The companies will inspect containers and condemn them if cracked welds, twisted frames or pin holes are found, among other faults.

Many structures based on shipping containers have already been constructed, and their uses, sizes, locations and appearances vary widely.

When futurist Stewart Brand needed a place to assemble all the material he needed to write How Buildings Learn, he converted a shipping container into office space, and wrote up the conversion process in the same book.

In 2006, Southern California Architect Peter DeMaria, designed the first two story shipping container home in the U.S. as an approved structural system under the strict guidelines of the nationally recognized Uniform Building Code (UBC). This home was the Redondo Beach House and it inspired the creation of Logical Homes, a cargo container based pre-fabricated home company. In 2007, Logical Homes created their flagship project - the Aegean, for the Computer Electronics Show in Las Vegas, Nevada.

Several architects, such as Adam Kalkin have built original homes, using discarded shipping containers for their parts or using them in their original form, or doing a mix of both.

In 2000, the firm Urban Space Management completed the project called Container City I in the Trinity Buoy Wharf area of London. The firm has gone on to complete additional container-based building projects, with more underway. In 2006, the Dutch company Tempohousing finished in Amsterdam the biggest container village in the world: 1,000 student homes from modified shipping containers from China.

In 2002 standard ISO shipping containers began to be modified and used as stand-alone on-site wastewater treatment plants. The use of containers creates a cost-effective, modular, and customizable solution to on-site waste water treatment and eliminates the need for construction of a separate building to house the treatment system.

Brian McCarthy, an MBA student, saw many poor neighborhoods in Ciudad Juárez, Mexico during an MBA field trip in the 2000s. Since then he developed prototypes of shipping container housing for typical maquiladora workers in Mexico.

Application for the Live Event & Entertainment Industry: in 2010 German Architect and Production Designer, Stefan Beese, utilized six 40’ long shipping containers to create a large viewing deck and a VIP lounge area for to substitute the typical grand stand scaffold structure at the Voodoo Music Experience, New Orleans. The containers also smartly do double duty as storage space for other festival components throughout the year. The two top containers are cantilevered nine feet on each side creating two balconies that are prime viewing locations. There are also two bars located on the balconies. Each container was perforated with cutouts spelling the word “VOODOO,” which not only brands the structure but creates different vantage points and service area openings. And since the openings them self act as signage for the event, no additional materials or energy were needed to create banners or posters.

In the United Kingdom, walls of containers filled with sand have been use as giant sandbags to protect against the risk of flying debris from exploding ceramic insulators in electricity substations.

Markets

Empty shipping containers are commonly used as market stalls and warehouses in the countries of the former USSR.

The biggest shopping mall or organized market in Europe is made up of alleys formed by stacked containers, on 69 hectares (170 acres) of land, between the airport and the central part of Odessa, Ukraine. Informally named "Tolchok" and officially known as the Seventh-Kilometer Market it has 16,000 vendors and employs 1,200 security guards and maintenance workers.

In Central Asia, the Dordoy Bazaar in Bishkek, Kyrgyzstan, almost entirely composed of double-stacked containers, is of comparable size. It is popular with travelers coming from Kazakhstan and Russia to take advantage of the cheap prices and plethora of knock-off designers.

In 2011 the Cashel Mall in Christchurch, New Zealand reopened in a series of shipping containers months after it had been destroyed in the February earthquake that devastated the city's central business district.

For housing and other architecture

Containers are in many ways an ideal building material because they are strong, durable, stackable, cuttable, movable, modular, plentiful and relatively cheap. Architects as well as laypeople have used them to build many types of buildings such as homes, offices, apartments, schools, dormitories, artists' studios and emergency shelters. They are also used to provide temporary secure spaces on construction sites and other venues on an "as is" basis instead of building shelters.

Phillip C. Clark filed for a United States patent on November 23, 1987 described as "Method for converting one or more steel shipping containers into a habitable building at a building site and the product thereof". This patent was granted August 8, 1989 as patent 4854094. The diagrams and information contained within the documentation of this patent appear to lay the groundwork for many current shipping container architectural ideas. Even so, this patent does not appear to have represented a novel invention at its time of filing (Paul Sawyers described extensive shipping container buildings that were used on the set of the 1985 movie Space Rage Breakout on Prison Planet).

During the 1991 Gulf War, containers saw considerable nonstandard uses not only as makeshift shelters but also for the transportation of Iraqi prisoners of war. Holes were cut in the containers to allow for ventilation. Containers continue to be used for military shelters, often additionally fortified by adding sandbags to the side walls to protect against weapons such as rocket-propelled grenades ("RPGs").

The abundance and relative cheapness of these containers during the last decade comes from the deficit in manufactured goods coming from North America in the last two decades. These manufactured goods come to North America from Asia and, to a lesser extent, Europe, in containers that often have to be shipped back empty, or "deadhead", at considerable expense. It is often cheaper to buy new containers in Asia than to ship old ones back. Therefore, new applications are sought for the used containers that have reached their North American destination.
