VAC is the abbreviation of the Vietnamese words Vườn (Garden), Ao (Pond), Chuồng (Cage) – an integrated production systems in the rural areas comprising three components: horticulture, aquaculture & animal husbandry. VAC systems, therefore, effectively use all the available energy from land, air, water and solar energy resources, and also effectively recycled generating products and waste.

In present-day Hanoi, Vietnam, people tend to create small landmarks in their homes, including the placement of fish ponds, which may be small aquariums or Koi ponds with higher investment.

In addition, the situation of vegetable contaminants in the city also causes the desire to plant fresh vegetables right in resident homes became imperative. Nowadays, many families organize planting vegetable at home, however, mostly following to spontaneous methods, without a strategic planning or architectural aesthetics. These are vegetable foam boxes that are placed in a narrow space in the house, or in the garden area of the balcony and top terrace.

Farming Architects is re-designing the VAC system to be implemented in an urban area. The aim is not only to produce an effective use of natural resources but also favourite experimentation in using different types of plants and animals in urban environment.

The core feature for the design of VAC is the Aquaponics, it is a system that combines conventional aquaculture (raising aquatic animals) with hydroponics (cultivating plants in water) in a symbiotic environment.
