Ville et fortifications : de l'héritage à la production du territoire urbain
2015
A large number of french cities host military historical edifices (citadels, barracks, bastions, defensive walls, etc.). Although their initial defensive functions have been lost over time, these edifices remain deeply rooted in the urban fabric of their host cities. They continue exerting an impact on these cities’ urban morphology and modern-time functions as well as the way in which the concept of city is understood. Cities nowadays face some new challenges,the increasing awareness of urban sprawl and its consequences, coupled with an urge to promote a renewed and sustainable urbanism, invites us to adopt new approaches to study urban fortifications. In addition to their symbolic aspect,…
ELEMENTARE E COMPLESSO. La Città per isole. Grammatiche insediative per la città contemporanea
2020
Studiando il lavoro sulle “composizioni alla scala della città” che Antonello Russo ci propone attraverso le elaborazioni dei suoi studenti, appare subito evidente un pensiero sulla forma urbana. Si manifesta l’idea di costruire gli isolati residenziali come singole architetture, nuclei urbani concepiti come un’unica grande casa in cui gli spazi liberi fra gli edifici diventano luoghi del progetto. È in questi spazi che la città rivela il suo intento rappresentativo, che si rende riconoscibile, che diventa teatro della vita degli uomini. Il libro di Antonello Russo è testimone di un’idea di città in cui sono contenute le aspirazioni di una moderna cultura dell’abitare, un’idea di spazio dov…
Urban form in the tourist cities of the coast of the Canary Islands. The morphologies of leisure
2017
The tourist city has been a space with few and weak reflections from the urban discipline. The developed planning, at best, has been uncritically exported from the residential city. However, in these cities, almost 12% of Spanish GDP is generated. The vast majority of Spanish coasts, especially on the Mediterranean coast and in the archipelagos, are occupied by large areas of holiday cities. Many of them were born in the first boom of Spanish tourism in the 60's. The mass tourism model, predominant in our coast, also generates a mass city. The morphology of this city does not follow the common and more consolidated patterns of the residential city. Today many of these tourist destinations b…
The Hybrid Block as Urban Form
2018
The Hybrid Block as Urban Form Javier Pérez Igualada Escuela Técnica Superior de Arquitectura, Universitat Politécnica de València. Camino de Vera, s/n. 46022 Valencia. E-mail: jperezi@urb.pv.es Keywords: Hybrid Block, Urban Form, Mixed Use Buildings, Open Planning Conference topics and scale: Urban form and social use of space In this paper we analyze the hybrid block as an urban form of synthesis, in which the open order of modern urbanism is superimposed on the closed order of traditional urbanism. In this model, proposed for the first time by Hilberseimer in his 1927 Vertical City, housing and work are not separated but overlapping on mixed-use buildings, where the dwellings are loc…
A normative planning approach for the Luxembourg : assessment based on spatial simulation
2015
In Luxembourg, daily mobility patterns of both cross-border workers and residents lead to a strong car dependance. This process encourages urban sprawl. Meanwhile the country is faced to increasing housing needs but has to reduce land consumption. Within this context, the main objective of this thesis is to throw light about the relation between residential growth patterns and daily mobility behaviors. In this way, a normative planning approach has been adopted. This approach proposes new planning norms for achieving a series of planning objectives. Quantitative rules are the tools used to apply the norms.Three steps has been done: i) conception of residential growth scenarios for 2030. By …
Conceptualisation et évaluation d'une typologie de lotissement vertical pour un aménagement urbain durable
2020
The current urban development process is the result of a paradoxical situation. On the one end, families prefer individual housing, which finds the favourable conditions to its spreading in the more or less distant from towns outskirts, while wishing to benefit from services (proximity to amenities, public transport offers, etc…) which are rather the corelate of dense urban centralization. On the other hand, in order to fight against environmental, social and economic costs of urban sprawl, and also aim towards a more sustainable city, the urban renovation and compact city projects lead to some density levels that only collective housing enables to reach. So, the equation - control of the u…
How green neighbourhoods make cities more compact?t? A 2D microeconomic perspective
2014
National audience; We analyse the emergence of scattered residential development, a key characteristic of sprawl. We analyse a 2D urban economic model with neighbourhood interactions among households (social contacts) and with farmers (who produce green amenities). Starting from a cross-shaped road network and CBD, we analytically establish the existence and characteristics of residential leapfrogging that breaks up the compact development of the city. We extend our analysis by numerical experiments based on observed or econometrically estimated parameters. We nd that the shape of built up areas in uences the decision or not to jump over undeveoped land or to stick to the contiguous urban f…
Is there a link between fractal dimensions and other indicators of the built-up environment at a regional level
2008
International audience; Fractal dimension is used to measure the spatial arrangement (morphology) of built-up areas within a Nuts1 region (Wallonia, Belgium) and, more particularly, to test to what extent fractal dimension is related to some variables commonly used in urban economics/urban geography to characterise built environment, housings and residential choice (such as land price, housing rentals, history of urbanisation, type of housing). Special attention is put on the link with the perception of the built environment by households. A multivariate analysis concludes the paper. It is shown that fractal indices differ from other indicators and are very useful for characterising and und…
Postmetropoli in contesti al 'margine'
2014
Il sud Europa, ad eccezione del nord Italia, è considerato come una porzione 'marginale', la 'meno globale' del continente e fino a poco tempo fa c'era chi lo dipingeva come appartenente al 'Terzo Mondo'. La Sicilia e considerata al limite di questa 'marginalità' e, per molte ragioni, lo è. Eppure, nuovi processi sono in corso. I territori siciliani stanno attraversando notevoli fasi di cambiamento fisico, sociale ed economico, mostrando una transizione, per molti aspetti inedita, verso forme post-metropolitane. Si tratta di aree per molti aspetti paradigmatiche in grado di restituire le diverse nature del 'post' sotto il profilo spaziale, economico, demografico e sociale. Si affronterà, d…
