Primeras políticas de vivienda en España y su influencia en la evolución de la tipología residencial: el caso de Benalúa (1883-1956)

El estudio del proceso de adaptación tipológica de las arquitecturas residenciales del barrio de Benalúa, una de las áreas consolidadas más singulares de la ciudad de Alicante (España), constituye un ejemplo clave para entender el alcance que tuvieron las primeras políticas de vivienda aplicadas en ese país, con anterioridad a la redacción de los Planes Generales que, en el transcurso del siglo XX, fueron ordenando las ciudades españolas y que en el caso de Alicante coincidió con la aprobación de la primera Ley del Suelo estatal (1956). De su análisis se obtienen las conclusiones que identifican los procedimientos que, por cambios sociales, políticos, de normativa o presión del mercado inmobiliario, condicionaron la evolución de la vivienda durante siete décadas, huellas que en la actualidad vienen desapareciendo a un ritmo vertiginoso, constatando el grado de intervención del Estado y de los municipios, así como su influencia y responsabilidad en la determinación de los tipos edificatorios.

The other architecture: From natural caves to excavated housing

Excavated towns are an attractive example of underground urbanism that managed to solve, in a very interesting way, thermal problems thanks to natural ground inertia or transition spaces. The aim of this paper is to show the typological evolution of excavated dwellings worldwide, as an architectural proposal and urban solution. The proposed methodology provides an analysis of underground architectures from natural caves to excavated housing, focusing on the study of global constructive solutions to specific problems. Thus, architectures as a natural geography correction (horizontal excavation), buried underground architectures (vertical excavation), subtractive architectures (shallow excavation) and combined architectures (mixed excavation) are studied. In conclusion, there are many examples of typological combinations since troglodyte architects tried to adapt the most elementary constructive rules to get greatly enriched results. These proposals of different underground structures deal with each territory and its geographical features, and obtain urban and architectural solutions transferable to current configurations.

Excavated housing in Crevillente (Spain). Constructive and typologycal study

Underground architecture has sheltered man for many centuries, but the current need to emphasize the bioclimatic approach makes the study of excavated housing essential. This traditional construction is a part of the collective human living experience but also a reference in using the natural conditions of each region through simple proposals based on ground thermal inertia. The aim of this paper is to show the typological evolution of the excavated dwelling in Crevillente, in southeast Spain, compared to other worldwide architectural proposals or urban solutions. To show their adaptation to the regional geography and to comprehend both formal and material characteristics of these simple typologies, which do not need extra energy contribution for interior conditioning. This work is part of the doctoral thesis of the author.
