O vale de Alcântara, património biofísico da cidade, contém um desmesurado aglomerado infraestrutural no seu leito, proporcionador de áreas fragmentadas que geram impedimentos de atravessamentos entre as suas margens, e a segregação socio-espacial dos bairros adjacentes, sendo neste contexto que emerge a necessidade de intervenção no âmbito deste Projeto Final de Mestrado.
A proposta desenvolvida tem por base um olhar sobre o passado do vale de Alcântara enquanto sistema de escoamento natural de Lisboa, que se foi perdendo ao longo dos anos devido à evolução infraestrutural em prol da priorização do automóvel. A intervenção consiste numa ação de renaturalização do vale, retornando ao de cima a sua ribeira, atualmente encanada, sem esquecer o seu carácter natural e de subsistência de outrora, através da criação de diferentes áreas verdes produtivas e de contemplação que albergam espaços de permanência. De forma complementar, propõe-se a redistribuição do seu tráfego ao nível do subsolo, que garanta a sua integração com a cidade consolidada, ambicionada também a nível urbano.
Nesse contexto, o intuito passou igualmente pela renovação das áreas adjacentes aos bairros existentes ao longo do vale, com enfoque na Rua Maria Pia e encosta do Casal Ventoso, em que se propõe uma solução urbana, que prioriza a coesão social e espacial através da qualificação do espaço público e permeabilidades pela encosta, bem como, arquitetónica, que preveja a evolução das necessidades dos agregados familiares e diferentes modos de habitar.
The Alcântara’s valley, city's biological heritage, contains an unmeasured agglomeration of infrastructure on its bed that creates fragmented areas that difficult the crossings between its borders and separate the adjacent neighbourhoods statical and socially, what can justify the situation’s urge of intervention within the scope of this final master's project. The developed proposal is based and takes inspiration from the Alcântara Valley's historical role as Lisbon's natural irrigation system, which was lost over time due to the infrastructural evolution in favour of the the city's prioritisation of automobile vehicles. The intervention consists in a valley’s renaturalization action, by restoring its riverside, currently channelled, without forgetting its natural features from the old days that helped in the family’s subsistence, through the creation of several green productive and contemplative areas that contain spaces fo permanence. In a complementary way, it is proposed to redistribute its traffic to the underground level, that could ensure its integration with the consolidated city, ambitioned also at the urban level. Within that sense, the purpose was also the renovation of the adjacent areas close to the existing neighbourhoods throughout the valley, focusing on Maria Pia’s Street and the Casal Ventoso’s slope, where it is proposed an urban solution that prioritises social and spatial cohesion thought public space qualification and permeabilities through the slope, as well as architectural, that predicts the evolution of the family’s needs and different ways of living.
