The Biddle House is possibly one of the most iconic suburban houses in the Sotogrande resort. In this scattered American style urbanization, there are many large avenues, sports complexes and, above all, the traditional Andalusian architecture of the villas and farmhouses. And there you can find, apart from this house by Javier Carvajal, some other examples of rationalist architecture such as the golf club by Luis Gutierrez Soto, or a hotel by Jose Antonio Corrales. This article seeks to address the context and architectural analysis of the Biddle Duke family house. In it one can venture a dichotomy between the pragmatic and the poetic. Its compositional strategy revolves around a simultaneously classic and modern cloister, enshrined and at the same time filtered towards the landscape. This patio that articulates the whole project reaches here a poetic and almost monumental dimension, which is combined with the repetitive rationality of the succession of groin vaults. And this double condition impregnates the entire domestic space. There, the Mediterranean essence of the patio coexists with the rationalism of the modular grid; the austerity of the materials synchronizes with the poetry of the white volumetry of the vaults; and the sobriety of the finishes concurs with the formal purity of the arch work.
