District Sub Centres as Foundational Elements in the Implementation of the 15 Minute City Model: Case Study of Albertfalva

The 15-minute city model aims to enable residents to reach the facilities necessary for everyday life within 15 minutes on foot or by bicycle. This study uses the example of Budapest's Albertfalva (sub)district (neighbourhood) to examine how district sub-centres could contribute to the implementation of this model. It was found that, while certain urban functions are present, community and service spaces do not form a real centre. Developing the area surrounding the former market building could fulfil this role. The results emphasise that designating central spaces is not an end in itself, but can be a vital step towards urban decentralisation and sustainability.
