pihlmann architects' renovation of '50s house14a in copenhagen blends old and new

Pihlmann Architects’ adaptive reconfiguration of House14a

House14a in Copenhagen, designed by Pihlmann Architects, embodies a non-hierarchical approach that reflects an ongoing narrative of evolution. The project highlights a continuous process rather than a finished work, where each element, whether old or new, rough or refined, holds equal significance. This approach allows for ongoing adaptation and reconfiguration.

Originally built in 1951, the single-family home represented post-war residential styles with its two-story cubic design, red brick facade, and gable roof. While structurally sound, it lacked flexibility for evolving lifestyles. Traditional architectural techniques, such as exposing, covering, cutting, joining, stacking, and casting, were employed to dissolve the rigidity of the original structure.

The introduction of three interposed masonry cores, housing essential elements such as storage, stairs, and pipework, facilitated a functional transformation. These cores create residual spaces that offer fluid, inhabitable areas between them. The additions reference existing elements without replication, subtly differentiating themselves from the original materials in terms of dimensions, tone, and composition.

Merging Original Craftsmanship with Modern Techniques

Elements removed from the original structure, like crushed bricks repurposed into terrazzo flooring, merge seamlessly with the additions. Pihlmann Architects‘ interventions respect the original craftsmanship while embracing modern machinery and prefabricated components. Subtle changes, such as regrouting the exterior brickwork, and distinct interior modifications engage with the existing structure without overshadowing its character.

The transformation emphasizes an openness to unpredictability and thrives on tactile experimentation. The construction site functioned as a studio and laboratory, fostering continuous dialogue among the client, craftsmen, and architect. This on-site collaboration laid the groundwork for intentional, measured progress, allowing the house to remain an unfinished collage that evolves with time.

By embracing uncertainties and focusing on transition rather than completion, House14a acknowledges its role in a broader continuum, paving the way for future transformations and adaptations.
