Rammed Earth Structure With Natural Timber Accents Creating Community-Centric Spaces

Project in-detail

Crafted from rammed earth and accented with natural timber, this community-focused structure integrates sustainable practices and biophilic design to facilitate social interaction and shared living.
5 key facts about this project
01
Rammed earth construction enhances thermal mass and energy efficiency.
02
Natural timber accents provide visual warmth and local character.
03
Interior gardens promote biophilic design and resident well-being.
04
Compost toilets support sustainability and reduce water consumption.
05
The shell-like shape facilitates seamless indoor-outdoor connectivity.

A Concha represents a thoughtfully conceived architectural project located in Pinhão, Vila Real, Portugal. This design emphasizes sustainable living through the careful selection of materials and spatial organization that enhances connectivity with the surrounding environment. The architectural form draws inspiration from natural elements, specifically resembling a shell, which symbolizes harmony between structure and nature.

The primary function of A Concha is to serve as a communal gathering space, promoting social interaction among residents while providing essential facilities. This project integrates residential, recreational, and shared spaces that meet the needs of its community. The architecture not only accommodates daily activities but also facilitates events and gatherings, making it a focal point for communal life.

Innovative Design Strategies

A Concha employs rammed earth as a primary construction material, capitalizing on its durability and thermal properties, which contribute to natural climate control. Timber is used for structural elements, lending warmth to the interiors. The intricate use of mosaics adds aesthetic appeal and local cultural reference, enhancing the identity of the structure within its context. Anodized panels serve both functional and visual purposes, providing privacy while allowing natural light to permeate the space.

The layout of A Concha is designed to promote fluid movement between indoor and outdoor areas. Key features include interior and exterior gardens, which provide recreational opportunities and contribute to the overall well-being of residents. Communal kitchens and gathering areas are strategically placed to encourage social interaction and community engagement. Compost toilets exemplify a commitment to sustainability, minimizing environmental impact while addressing essential needs.

Sustainable Solutions

A Concha is equipped with photovoltaic panels that facilitate energy independence. The layout promotes natural ventilation, minimizing reliance on mechanical cooling systems. The landscaping harmonizes with the local ecosystem, enhancing biodiversity while offering spaces for food production and leisure.

Overall, A Concha exemplifies a modern architectural response to communal living and sustainability, with an emphasis on holistic design principles.
