Daiwa House, Japan's largest homebuilder, has introduced a line of prefabricated hydroponic vegetable factories, aimed at housing complexes, hotels, and top-end restaurants. Called the Agri-Cube, these units are touted by Daiwa as the first step in the industrialization of agriculture, to be located in and amongst the places where people live, work, and play.
More and more people desire sustainable, organic produce for their own use, and are turning to urban farming in an effort to insure the highest degree of freshness. However, some municipalities, neighborhoods, and homeowners associations have rules that effectively block such endeavors in areas under their sway. Add drought and pest control to the picture, and suddenly urban farming may seem more trouble than it is worth. There is a growing need for local supplies of freshly grown produce that avoids the difficulties presented by conventional small farms and gardens.

This is where the Agri-Cube comes in. Measuring less than five meters (about 16 feet) in length and 2.5 meters (about 8 feet) wide, Daiwa's Agri-Cubes are smaller than a twenty-foot equivalent shipping container. An Agri-Cube can be brought to an installation site on the bed of a light heavy-duty truck. A concrete foundation about 10 square meters (108 square feet) in size must be prepared before delivery, along with plumbing and electrical utility hookups. Daiwa claims each Agri-Unit can grow about ten thousand servings of fruits and vegetables each year at an operations cost of about US$4,500, which corresponds to only 45 US cents per head of lettuce.
An Agri-Cube is designed to require little maintenance or attention to the hydroponic and lighting systems. It is delivered ready to use, with all the hydroponic equipment, air conditioning to maintain ideal growing temperatures, a heat-exchanging ventilation system, and special growth lights to encourage faster plant growth installed and functioning. The basic structure is a steel frame building, with anti-rust treatment and floor, wall, and ceiling insulation. Solar panels and air curtains (to better maintain the controlled environment) are available as options.
Initially, Agri-Cubes will be marketed to the food service industry. Daiwa intends to extend that focused niche market to include apartment houses and other housing complexes, neighborhood co-ops of perhaps ten households, small-scale stores, and local organic food suppliers.

Beginning at a price of $70,000, the Agri-Cube may soon be dispensing fresh fruit and vegetables in your neighborhood.
