Contemporary cities display a complex picture of different urban forms typified by built-up areas with different buildings patterns and open spaces layouts.

Abstract
Contemporary cities display a complex picture of different urban forms typified by built-up areas with different buildings patterns and open spaces layouts. These morphology types are differently characterised by high level of impervious surfaces and limited amount of greenery which can expose to climate change related risks. To cope with these issues, Nature-Based Solution (NBS) have emerged as a strategy to deploy and manage urban ecosystems through providing urban Ecosystem Services (UES). In order to better understand the complex morphological features of urban fabric and recognise the actual suitability of hosting new greenery, this study proposes a four-steps methodology for exploring challenges and opportunities to integrate NBS in four different morphology types: (i) Land-use and Land cover Analyses for drawing an overall picture of the land pattern and bio-physical features; (ii) Buildings maintenance & Land quality (B&L) and Landownership Analyses in order to explore the quality and maintenance levels of buildings and open spaces while identifying the current situation in terms of property asset; (iii) a Land Transformability Scenarios Assessment to evaluate the aptitude of land to host NBS; (iv) an UES assessment to estimate the potential of NBS in different morphological types to provide UES. Accordingly, four scenarios (Minimum Public, Public heritage, Private and Transformation) are drawn alongside the morphology types of historic fabrics, terraced houses, multi-storey apartment buildings and detached houses.
