The process of urban regeneration represents an opportunity for the sustainable reconfiguration of cities. This paper aims to present two good practice models of mixed-use real estate developments, by developing integrated concepts, with major impact on local urban and economic development, without being invasive. The two integrated urban regeneration projects are centrally located in first-tier cities in Romania and developed as a result of private initiatives, which aim at both the sustainable development of local communities and harmonization with the existing urban landscape. In order to meet the requirements of sustainable development, the projects are developed in such a way as to comply with the principles of "walkable cities", which not only facilitate pedestrian access but also encourage it by allocating large spaces to pedestrians and ensuring connectivity with the city through alleys and green spaces. The paper follows the spatio-temporal evolution of the projects, both in terms of environmental impact and economic and social.
