102 Dwellings in Carabanchel


这是 dosmasuno arquitectos 完成的一个社会住宅项目的建筑设计,位于西班牙。项目包括52个单卧室住宅,35个双卧室住宅,以及15个三卧室住宅。所有住宅都源自于一个通用的单卧室结构,双卧室与三卧室只是在该结构基础上进行了悬臂式添加。


High accuracy casts have already been used by the EMVS, who had the chance to test their results and performance. This project introduces an important innovation in the constructive process by fabricating the casts in aluminium. This implies a considerable lightening of the pieces, which enables the workers to manipulate them safely and without any additional cranes.

The Project for 102 social dwellings in Carabanchel consists of 52 single-bedroom dwellings, 35 double-bedroom dwellings and 15 triple-bedroom dwellings. A common dwelling cell was developed for the single-bedroom typology, which becomes double or triple-bedroom typology by the attachment of cantilevered additions. Thus, the project is made up of an invariant core- repeated 102 times- which justifies the implementation of this industrialized system. The aluminium casting system defines the core’s distribution (single-bedroom dwelling), including façades, dividing walls, partitions and even wardrobes. These walls contain, once cast, an isolating sheet (the external ones) and the whole services network. Extra-bedrooms, added in order to extend the dwelling surface, consist on light steel structure modules which are attached to the concrete façade, and fixed to pre-set hangers.

Once again, this system responds to the necessity of an optimized industrial process: a main concrete body, accurately cast with the single aluminium ‘mould’ plus the light skeleton additions, which enable the façade variations.

The process is similar to the one implemented in the industrial automobile production system, in which each worker is committed to a single assembling phase, increasing the efficiency of the whole chain. It starts with the layout of the dwelling walls on top of the lower slab, and continues with the setting of the vertical reinforcements, which are able to stand by themselves. Then, spacers are put in order to keep them in a straight position, as well as the isolating panels (just in the façade walls), located between the vertical reinforcements. The walls’ girth has been simplified into two types: façade walls, 24 cm (10 cm + 4 cm insulation + 10 cm) and the rest -dividing walls, partitions and wardrobe walls-, 10 cm. They are all bearing walls. Once the reinforcements and the isolation panels are set, the services are placed into the 10 cm-girth walls, with the exception of the heating system, which is distributed throughout the slab’s girth perimeter. The next step is the setting of the aluminium cast, coming entirely from the nearby dwelling, and the concrete pouring. Last but not least, window placing, paint job, floating parquet setting over the auto-levelling slab and bathroom and kitchen tiling.

The execution rate is daily, for it is possible to set/remove the casts and pour the concrete within the same day, being able to work on other tasks at the same time. Henceforward, the system performance is one dwelling per day. The advantages of this industrialized system are the quick setting-up, which speeds up the execution period and avoids rubbish production. On the other hand, it implies an increase in the material cost, due to the amount of concrete used, greater than in conventional construction.

The system implies a possible disadvantage concerning the user, and this is the scarce possibility of carrying out further renewals within the dwellings, for every single wall has a structural role. However, this possibility was dismissed for two reasons: firstly, as the dwelling surface is rather limited (between 42 and 66 sqm), other spatial possibilities would be quite similar to the established, and secondly, and most important, the dwellings are intended to be hired, and, therefore, any extension/renewal would be forbidden.

The external finish ensues as a result of the building’s different orientations, in order to achieve an adequate climatic response, as well as a sustainable climatic performance. The main rooms (living room and main bedroom) of each dwelling face South-East/South-West, whereas kitchens, bathrooms and secondary bedrooms face North-East/North-West. The insulation mass is mainly kept in the internal part of the façade, increasing the dwelling’s thermal inertia. In winter, this prevents the building from a quick loss of its temperature, whereas, in summer, it helps to avoid extra heat from the outside.

In addition to this main insulation system, a white galvanized deployé façade is placed in the southern façades (white is the most reflecting colour and, therefore, the least solar-radiation absorbing), creating a ventilated double skin, set horizontally in the South-East side and vertically in the South-Western. This allows the winter’s horizontal solar radiation inside the skin, avoiding the summer vertical one, and concealing the building from the strong western exposure in Madrid’s summertime.

The northern façades are painted white, and the cantilevered bedrooms are covered with micro-perforated, galvanized metal sheets, white as well, working, once again, as a ventilated façade and protecting the inner sprayed polyurethane foam insulation.

Services are centralized and distributed to each dwelling through the access terraces’ structure, and thus avoiding any possible interference with the main concrete body. There is a solar-energy supporting system in the rooftop, also centralized, as well as a pre-installation for an air conditioning system in each dwelling, hidden from the external views. The service centralization is organized in the basement floor, open to the outside by means of huge voids, through which trees will emerge, and around which cars will be parked.
