As urban density increases and cities expand, there is a decrease in urban livability, which is closely linked to social, economic, and environmental crises. To address these negative impacts, biophilic urbanism (BU) promotes human–nature interactions and their associated benefits. However, knowledge gaps remain regarding its effectiveness across different scales. This study explores how BU contributes to improving livability in the built environment and to renewing urban landscapes. Using Amsterdam as a case study, we first identified biophilic experiences by analyzing them through quantitative, qualitative, and spatial distribution metrics. We then investigated designs that foster biophilia by applying BU tools aimed at enhancing interspecies connections and leveraging ecosystem services. Our findings, in the form of maps, provide evidence-based insights to benefit everyday life using nature in settings at different scales, along with design solutions to renew urban planning, focus on human and environmental well-being, and involve citizens in spatial transformations and maintenance processes. Finally, we advocate for BU as a holistic model that uses natural capital as a key strategy for making cities more equitable, sustainable, and resilient.

Leftover spaces are urban interstices that are open to spontaneous socioecological appropriation, complementary to defined and managed urban open spaces. The design intervention of leftover spaces poses a paradox: while repurposing leftover spaces to make them accessible, usable and meaningful, design simultaneously runs a risk of closing off opportunities for appropriation. This paper examines the role of landscape architecture design in transforming leftover spaces. Four analytical lenses: the morphological, material, ecological and social lenses, were developed to examine the Dalston Curve Garden. Two essential design lessons for engaging the interstitial condition of leftover spaces were concluded: to design with multiple site qualities and to nurture local stewardship. The study further highlights the role of spatio-physical design as ‘founding’: to establish the beginning of a place-bound transformation without fixing the endpoint and to allow a profound connection between people and place to emerge.
