In the heart of Copenhagen, Danish designer Sara Martinsen has conceived a guesthouse that redefines the concept of architectural sustainability. This urban shelter, built entirely with native plant materials from Denmark, is not only a sample of conscious design, but also an invitation to reconnect with nature through architecture.
A conscious project with vegetal architecture
The project is a response to the growing need for environmentally friendly housing solutions. Martinsen has meticulously selected each material, prioritizing those of plant and local origin, such as flax, hemp and wood from Danish species. This choice not only reduces the building’s carbon footprint, but also celebrates the country’s botanical richness.
The structure of the house is based on traditional construction techniques, adapted to contemporary requirements of energy efficiency and comfort. Thermal insulation is provided by compacted plant fiber panels, while cross ventilation and the strategic orientation of the openings ensure natural air conditioning. The color palette, dominated by earthy and organic tones, reinforces the integration of the building with its surroundings.
Integration with the environment in the details
One of the highlights of the design is the attention to detail in the interior finishes. Martinsen has worked with local craftsmen to develop solutions that combine functionality and aesthetics, such as wall coverings made from linen fabrics dyed with natural pigments and furniture made from wood treated without chemicals. These elements not only bring warmth to the space, but also tell stories of tradition and know-how.
This project is not just a place to stay; it is a sensory experience that invites visitors to reflect on their relationship with the environment. Every nook and cranny is designed to foster calm and introspection, from common areas bathed in natural light to private spaces offering framed views of the surrounding landscape.
This project by Sara Martinsen exemplifies how architecture can be a powerful tool to promote sustainable practices and strengthen the bonds between people and nature. By using exclusively local plant materials and environmentally friendly construction techniques, the guesthouse in Copenhagen positions itself as a role model in contemporary ecological design.
