House Calumbi by Amanda Neuberger: Sustainable Residential Architecture in Chapada Diamantina

Nestled in the scenic rural landscape of Lençóis, Bahia, House Calumbi by Amanda Neuberger is a compelling example of sustainable residential architecture that harmoniously engages with the Chapada Diamantina environment. Situated in a transitional zone between the cerrado and caatinga ecosystems, the house responds to the unique climatic and topographical challenges of the region—steep hills, valleys, and a hot, dry climate punctuated by intense seasonal rains.

Site Integration and Architectural Concept

House Calumbi was designed to blend seamlessly with the natural terrain rather than altering it. By splitting the program into two distinct blocks—social and private areas—positioned at different levels, the design minimizes land movement and preserves the existing topography. A central staircase, organized around a vertical void illuminated by a translucent roof, serves as a spatial and visual connector, ensuring natural light penetrates throughout the day while enhancing circulation.

The building’s orientation and careful placement allow open views of the surrounding hills, making the natural environment an integral part of the experience. This approach exemplifies a design strategy that respects both the landscape and the local ecosystem.

Materials and Construction

The house employs conventional construction methods with a reinforced concrete structure and ceramic block masonry, incorporating locally sourced materials in select areas. Stone and solid brick are used strategically, sometimes forming hollow elements reminiscent of cobogós, which allow natural ventilation and filtered light to permeate interiors.

Stone, in particular, pays homage to local craftsmanship and the region’s mining heritage, establishing a cultural and historical connection while structuring and defining the house’s volumes.

Reuse and Artisanal Materiality

Sustainability extends beyond construction methods. In collaboration with Arquivo, salvaged materials such as frames, steps, ceilings, and floors from demolished buildings in Salvador were carefully curated and integrated into House Calumbi. This approach not only reduces construction waste but also imbues the interiors with unique artisanal character, enhancing the material authenticity of the spaces.

Sustainable Systems and Environmental Strategies

House Calumbi exemplifies a low-impact, autonomous home. Key sustainable features include:

• Rainwater harvesting and storage
• Local sewage treatment via a biodigester
• Photovoltaic energy generation
• Solar water heating

Passive design strategies complement these systems, using cross ventilation and zenithal lighting to reduce reliance on artificial climate control and enhance thermal comfort naturally.

A Home Rooted in the Territory

House Calumbi represents a holistic approach to residential architecture that values territorial identity, sustainable practices, and local craftsmanship. By integrating autonomous systems, reused materials, and culturally resonant techniques, Amanda Neuberger created a home that respects, inhabits, and celebrates the Chapada Diamantina landscape.
