The Pi project explores flexibility as a design principle, proposing an adaptable domestic structure capable of responding to changing patterns of living with minimal physical intervention. Located in a traditional Barcelona building, the apartment is reconfigured through a strategic redistribution that prioritizes spatial continuity, efficient infrastructure, and material coherence. The core of the project is a large central space that concentrates the collective functions of the home: living, dining, and cooking. The existing Catalan vaulted ceiling is preserved and refinished in white, enhancing the sense of depth and reflecting light throughout the longitudinal plan. Along one edge, a new linear kitchen integrates high-capacity storage and technical systems behind a continuous front of white cabinetry. The work surface is defined by a restored exposed-brick wall, cleaned and consolidated to reveal the original stratification of the building’s envelope. This material contrast provides texture while maintaining a neutral overall palette.

Radiating from this central room are three adjacent spaces and a bathroom. All technical installations—plumbing, ventilation, and electrical distribution—have been repositioned and consolidated to support multiple possible future configurations. In its current state, Pi functions as a generous one-bedroom apartment. By adding a single lightweight partition, it transforms into a two-bedroom dwelling; with a second partition, it easily becomes a three-bedroom residence. This adaptability is enabled by a non-hierarchical distribution, where doors, circulation routes, and service cores are positioned symmetrically to accept different programmatic arrangements without major construction.

Materials are selected for durability, clarity, and compatibility with the original structure. The new oak flooring in the main areas provides warmth and unifies the renovated spaces, while the preserved hydraulic tiles in the secondary rooms maintain a link to the apartment’s heritage. The bathroom is conceived as a compact, high-performance wet room lined with ceramic tiles, featuring integrated niches, black metal fixtures, and a frameless glass screen that maximizes light and usability. Throughout the intervention, the intention has been to strike a balance between architectural precision and domestic comfort. Lighting fixtures are mounted visibly on walls and ceilings, allowing for easy maintenance and clear legibility. Openings to the street have been restored to improve natural ventilation, while improving thermal performance through discreet upgrades to frames and glazing.

Pi demonstrates how a contemporary renovation can integrate technical foresight, spatial economy, and material respect. By enabling several layouts within one compact floor plan, the project offers a flexible, future-proof model for urban living, 
a home that can shift, expand, or contract as life requires.
