The paper regards the relationship between a unitary process valorisation advantages and the increase in value of the properties analyzed (assets or territorial areas).The aim of a unitary project is to enable a synergical and coordinated approach among the different stakeholders (authorities, property owners, investors) involved in the process of redevelopment of the area, and the assets involved in the process. The success of a Model of territorial development is given by the minimization of risks related to the valorisation of real estate portfolio analyzed. Lower risks, reduce uncertainty of exit, easier disposal of assets leads to an increase in value.Some advantages of this approach: 1. the creation of synergies by exploiting the network structure of the Assets; 2. the activation of a process consistent with the broad urban and regional development;3. the ability to create offsets between different asset value to prevent disparities between properties with higher value and marginal; 4. the creation of real estate instruments in line with the vocation of the territory, with the strategic guidelines and with the real estate market conditions.The valuation model is based on a matrix that analyze factors, such as: the economics, the social context, asset quality, environmental and geological situation and others. The method will be implemented with the market, territory and stakeholders in order to contain any leakage of value and ensure successful initiative.
