Housing shortage after urban disasters is often approached by governments and humanitarian organisations by building prefabricated houses that, during the transition between emergency and reconstruction, materialize the paradox of the permanency of a temporary situation. The events that followed the 2016-2017 seismic crisis in Central Italy do not seem to be an exception: in absence of permanent houses, the displaced people have been accommodated in S.A.E. (housing emergency solutions) within temporary villages of heterogeneous social, spatial and environmental qualities. With the aim to explore and improve way-finding in the disaster-impacted settlements as well as accessibility and sociability of the temporary sites' public open spaces, this paper proposes a human-centred design research approach in performance-based housing recovery planning and design decision-making, combining principles and methods from Space Syntax and Public Life Studies. This research demonstrates how to coordinate different digital analysis and design tools by illustrating their application in an urban regeneration project for Borgo1, a temporary housing settlement in the municipality of Arquata del Tronto. Specifically, the paper shows how a multi-scale and multidimensional study of the site allowed identifying the ideal location for a new public square and subsequently guided the design process towards the initial design goals' achievement.

Contraction, downsizing, rescaling and subtraction are all words that characterise the urban planning debate with increasing frequency. Two components can be found at the basis of their circulation and declination.On the one hand, the recognition of the vast unused and disused real estate for which regeneration, reuse and renovation are not possible; on the other hand, the will and hope to rebalance the results of the hypertrophic twentieth-century urban development. The legitimacy of these instances is the wides pread belief that demolition and contraction are low-cost operations that can be financed by the owners of the property or through the usual equalisation and negotiation mechanisms. By using a case study, this paper will clear up amis understanding; it will explain how demolition and subtraction costs, which can be put on equal footing with renovations and, in some cases, new construction are sufficiently massive making their implementation within the public and public-private policies very difficult.

Abstract. On September 30, 2013, the Giunta Regionale Toscana has approved a bill that is presumably destined to substitute the current regional law on the Governo del Territorio (L.R. 01/2005). The new law is going to prevent the new soil occupation for housing, thus radically and definitely closing the long lasting historic phase of the urban growth planning, hegemonic for over 80 years. The renovation and reuse of interstitial areas and the urban regeneration are therefore going to become the only possible intervention for supplying the housing needs of cities and local communities. The proposal has excited a strong debate among opposite sides of politicians, administrations, economic operators, professional and town planners; the law and the debate it is exciting is likely to strongly influence both the legislation of other Italian regions and, at a national scale, the bills on territorial and environmental issues to be discussed by the Italian Parliament commissions. The transition of urban regeneration from the project sphere, often limited within local and punctiform operations, towards a process-oriented and diffused approach involves the urgent needs to pinpoint new shared tools, suitable for managing and controlling complex and codified procedures, multiplicity of involved subjects and the transparent participation of local communities. The definition of such tool as planning support is certainly essential for the political intentions and law regulations to concretely determine new operational method. The purpose of this paper is to briefly sketch the state of the art of the present methods and procedures at urban and territorial scale as well as to outline new approaches and developments so as to meet the new normative needs concerning the regeneration.

L'articolo propone una metodologia di comparazione dei valori della rendita urbana utiliz-zando come marker i quartieri di edilizia residenziale pubblica costruiti in Italia nell'ambito dei Piani INA-Casa. Il confronto tra i valori fa emergere due aspetti ritenuti significativi: la forte differenziazione delle condizioni economico-immobiliari che caratterizzano il paese e il riconoscimento dell'ineliminabilità della rendita, che manifesta nei casi studio effetti economici del tutto rilevanti.
