BV9 is a minimalist residence located in Madrid, Spain, designed by BA-RRO. This renovation project demonstrates how spatial reorganization can transform domestic experience through strategic openings and diagonal interventions challenging inherited orthogonal layouts. The design philosophy treats renovation not as mere correction but as discovery process dismantling certainties and proposing new inhabitation ways, reflecting contemporary architectural discourse about how existing building stock can support evolved living patterns.
The house no longer defends itself from outside with view opening where blind wall once existed, unfolding in every direction connecting with city and light. The horizon once fragmented now frames itself through large open planes, demonstrating how fenestration modifications can dramatically alter spatial character and environmental relationships within existing structures. This opening strategy addresses typical Madrid apartment challenges where interior-facing units receive limited natural light and urban views.
A diagonal cutting through original structure on plan reflects existing framework diverting paths, shifting axes, breaking inherited orthogonality’s rigidity. What once were limits become transitions, demonstrating how non-orthogonal organizational strategies can create spatial dynamism within rectilinear building envelopes. This diagonal intervention challenges typical Madrid apartment plans organized around central corridors with perimeter rooms, instead creating varied circulation paths and spatial relationships.
The programmatic balance reformulation avoids opening everything without measure through planes that slide and doors functioning as thresholds rather than barriers. Spaces transform according to moment and inhabitants, demonstrating flexible planning approaches where rooms serve varied functions rather than fixed programs. This adaptability reflects contemporary understanding that domestic space must accommodate changing household compositions and daily activity patterns.
