Under present market conditions, the price of land is constantly rising, and cities are being shaped accordingly. Because the allocation of land for construction is carried out with the expense of land in mind, this has led to an increasing reduction of green areas in urban planning. As a result, we are witnessing a decrease in the quality of today's urban environment and the commencement of destruction of a livable urban environment. This study evaluated environmental factors such as green spaces and social reinforcement that raise the quality of urban life but which, due to being unrepresented openly on the market, are consumed as if they are free goods, or ignored. We investigated this issue according to four environmental attributes considered by individuals when buying a house or home in the city of Canakkale; namely, outdoor furniture elements, recreational areas, transportation, and psychological influences. The relationship between garden size and housing prices in the city center was also examined. The findings revealed that, when individuals were purchasing housing in the city, they were influenced by environmental attributes and, according to the quality of the environmental attributes relating to the house, the price increased proportionally.
