Since urban redevelopment is conducted by exchange of rights in an existing urban area, it requires some time for consensus building with local residents; however, when a new towns is constructed in areas that has not been urbanized yet, it is possible to acquire large area of land, such as land used for agriculture, for a relatively low price and to carry out effectively necessary procedures including urban planning decisions.
都市再開発は既存の市街地で権利変換を行うもので、地域住民との合意形成に時間を要するが、未だ市街化されていない地域で行われるニュータウン建設などの場合は、農地などの大規模な土地を比較的低価格で得ることが可能であり、かつ効率的に都市計画決定などの手続きを進めることも可能である。
