Agricultural marketing is an essential tool for development yet, farmers suffer from a number of difficulties that reduces their bargaining power, as they are deprived of getting the right price for their products. Data was sourced from a total of six cases, including three local and three Foreign. Architectural Data collected was analysed and used in the production of the Architectural design of a Farmer’s Market in Onitsha, Anambra State. Findings revealed that marketing involves several intermediary stages within the process. This often results in the consumer paying an exorbitant price and the producer receiving a lower price for his production. The marketing activity is obstructed by lack of sufficient fund, high cost of transportation, lacking market infrastructures, with little or no aid from government. Efficiency of marketing the crops was determined and problems identified through the movement of produce from producers, through the chain of actors in the markets.
