Purpose
Cities are facing challenges that dramatically affect their social and physical landscapes, leading to the increase of urban segregation and polarization. One response to these challenges is adaptive reuse, yet, in heterogeneous communities, these adaptations are often a source of conflict, because local actions often lack an integrative approach, leading to further exclusion. In this paper the authors explore the potential of adaptive reuse of urban heritage as a planning tool to support inclusiveness and heterogeneity.

Design/methodology/approach
The city of Acre is used as a case study, where different scenarios for urban heritage are proposed and tested among stakeholders through interviews. These aim to explore how adaptive reuse processes can lead to the inclusion or exclusion of certain groups and how design interventions in historic urban landscapes challenge the way the current disconnected historic and urban layers interact.

Findings
The paper presents the commonalities and differences between the interviewees' perceptions on Acre's functioning, their idea of inclusiveness and other aspects related to urban design. Moreover, it highlights the existing conflicts of interest, value prioritization and the adequacy of the proposed scenarios, serving as a way to verify the accuracy of the scenario building process.

Originality/value
Testing an urban design tool related to adaptive reuse of urban heritage in a real and extreme case, based on the guidelines of the Historic Urban Landscape Recommendation; and critically analysing the sources of conflict and value systems to address inclusion in heterogenous settings.
