So far, the garden city model has been analysed and adopted by scholars, urban planners, and institutions to design garden cities, new towns, and suburban communities as new settlements from scratch around the world. In contrast, this paper explores the potentialities of such a model to provide a multi-faceted approach based on territorial, socio-economic, and urban planning strategies, thus offering a series of policies to combat a wide range of issues in existing communities. For that purpose, this paper provides a new approach about the garden city model through the case studies of Letchworth and Welwyn Garden City and latest updated models to form a new scheme with the capability to encourage the decentralisation of population and means of production across the territory, develop cooperatives to achieve a self-financing system and affordable housing in existing communities, and implement the garden cities’ design principles for the regeneration and expansion of existing settlements towards a sustainable, attractive, self-reliant and prosperous future.

迄今为止，花园城市模式已被学者、城市规划者和机构所分析和采用，以在世界范围内从零开始将花园城市、新城镇和郊区社区设计为新的居住区。相比之下，本文探讨了这种模型的潜力，以提供基于领土、社会经济和城市规划战略的多方面方法，从而提供一系列政策来解决现有社区中的广泛问题。为此，本文通过 Letchworth 和 Welwyn Garden City 的案例研究以及最新更新的模型，提供了一种关于花园城市模型的新方法，以形成一个能够鼓励人口和生产资料在全境分散的新方案,
