Castelar House by @solar.xyz In Madrid’s Guindalera neighborhood, Castelar House by SOLAR reinterprets a historic typology through contemporary means. Behind a perforated steel facade, the residence opens into a secluded courtyard that blurs the boundaries between inside and outside. The design emphasizes light, ventilation, and material clarity - balancing modern detailing with echoes of the past. Passive strategies and a restrained palette lend the project a calm, deliberate atmosphere that evolves with its context. Photos: Adria Goula (@adriagoulaphoto) #industrial
