Vegetative barriers, arranged as isolating and filtering structures, are introduced into the urban tissue to improve the quality of urban air. As passive methods of space organisation, they are tools for mitigating, alleviating the effects of pollution and improving the comfort of space utilisation. The shaping of such objects is a process which requires taking into consideration numerous factors including the recognition of mechanisms and processes that occur between the barriers and the stream of pollutants, as well as meteorological and geometric conditions of the location.The method of organising vegetative barriers proposed in the present article has allowed for the inclusion of many aspects of the design process. This approach has provided a design procedure regime in a clear layout of individual stages. Based on the conducted implementation, a scenario of interactions of the vegetative barriers with the stream of pollutants was modelled, supplementing the canon of parameterisation of structures and employed qualities, relevant for the effectiveness of the composed plant assemblies in the process of cleaning the urban atmosphere of dust pollution.
