INTRODUCTION
Market as an institution for the exchange of goods and services, is as old as mankind. Record from the earliest civilization shows that trading in both local and foreign markets has been part of life. The earliest form of market was based on trading by barter. However, with the introduction of money as a means of exchange, commercial codes were developed, which ultimately led to modern national and international trade. Market plays a vital role in any society as an exchange mechanism and with socio-political life of the people. The market is an essential part in the chain of commodity distribution. Market serves as a mechanism of information, ranging from local, national and international levels (Arena, 1998).
The Nigerian National Commission on Agriculture defines agricultural marketing as “ A process which starts with a decision to produce a saleable farm commodity and it involves all aspects of market structure and systems both functional and institutional, based on pre-harvest and post-harvest operations, assembling, grading, storage, transportation and distribution †(Agricultural Marketing Resource Centre, 2007). In the past, agricultural marketing basically involved the buying and selling of agricultural produce, when the society’ economy was more or less self-sufficient, and farmer sold their produce to the consumer directly on a cash or barter basis. But in recent times, marketing of agricultural produce is different in modern marketing; Produce has to undergo a series of transfers or exchanges from one hand to another before it finally reaches the consumer. Hence, agricultural marketing ensures the supply and distribution of farm produce and inputs. For a market to attain a refined level of satisfaction, it should have adequate and accurate information about the supply and demand situation that is needed and necessary, if the products are to be moved to the place desired, at the proper time, in the desired form and at the appropriate price commensurate with the value of the product and or services.

But with the growing population of man, which is evidently seen in Onitsha, as at 2016 it had an estimated urban population of 7,425,000 people. Demand is on the increase, to strive in a commercial location the agriculture market will become a commercial character, as the farmer grows crops that fetch better prices. Marketing of agricultural produce is an integral part of the economy since a farmer is encouraged to make more investment and to increase production. Thus, there is an increasing awareness that it is not enough to produce a crop or animal product; it must be marketed as well. As a result, the crop production pattern is no longer based only on what the farmer needs for personal consumption but also what is in high demand and that fetches more return for them. Ultimately, prices of agricultural produce provide the signal by which farmers reduce or increase their output. This goes in line with the view of Adekeye and Dizzoh (1985) who observed that “improvement in agricultural productivity and living standards of small scale farmers are largely determined by the marketing systems in which they operate.â€Â
ÂÂ
The prices of agricultural produce is affected by characteristics and organization of the market in terms of structures, infrastructures, taxes, financing, information, rainfall variability, to mention a few. There is a need therefore to design better infrastructures for the marketing of agricultural produce.

1.2  STATEMENT OF ARCHITECTURAL PROBLEM
Everyone would love to have a healthy meal and fresh fruits, but there are discouraging thoughts that comes to mind, whenever we plan to go to the market to buy agricultural produce. These thoughts are the problem associated with majority of the Markets all over Nigeria. They include the congestion of people (human traffic), parking space (vehicular traffic), the nooks and crannies of the market (narrow footpath), thermal discomfort for the vendors, space for mass delivery of goods tends to be problematic, and the risk of fire outbreak.
1.3  AIM OF THE STUDY
To encourage the production and consumption of homegrown agricultural produce.
1.4  OBJECTIVES OF THE STUDY
The objectives that will be initiated to achieve the said aim includes:
ÂÂ
ÂÂ
1.5  SIGNIFICANCE OF THE PROJECT
This project would create a market that would have the answer to congestion, where farmers would be confident to sell their agricultural produce, hence encouraging the participation of individuals in the agriculture sector of the state and country at large. Ultimately providing more revenue for Anambra State Government.
ÂÂ
1.6  SCOPE OF WORK
The project area is heavily populated (Onitsha), to control the influx of people into the market area would be important. Therefore the scope of work would be inclined to providing spaces, and facilities that will aid in welcoming people (both sellers and buyers) and giving them a homely experience, a taste of the future market. These includes:
viii. Convenience

1.7  RESEARCH METHODOLOGY
Under research methodology there are two board types, namely Qualitative and Quantitative research methods.
Qualitative methods: Different sources were used while collecting the data used for this research purpose, though this method can be further classified into two:
Primary Sources: This is the collection of first-hand information or data. By obtaining information from a direct source which will constitute the following:
Secondary Sources: This is the collection of second-hand information or data. By the use of indirect sources which includes:
1.8  LIMITATIONS OF THE STUDY
Every project faces one challenge or the other, while discovering the truth behind the success or failures of that same facility that exists. Some limitations to this study are not having access to vital information such as the year of establishment of the market on which case studies were carried out, unwillingness of some the traders to tell information on how their business ran, effective case studies would best be carried out on markets that are of high standard, but a good number of case studies only had gave negative deductions.
ÂÂ
1.9  STUDY AREA
The location of this site is in Onitsha, Anambra state, Nigeria, Western Africa. Onitsha is divided into Onitsha North and Onitsha South, the project is prepared for Onitsha South LGA. Onitsha slowly grew into an important trading port for the “Royal Niger Company†in the mid-1850s. Trade in Palm Kernels, Palm Oil and other cash crops increased at this region in the 19th century.
From the 1900’s Onitsha has been a centre for Agriculture produce marketing. Therefore, it is no surprise that a Farmers’ market would be a fitting facility to be situated there.
