In the quest for sustainable building practices, architects are revisiting ancient techniques to construct homes that not only reduce carbon emissions but also provide unique aesthetic experiences. One such method is using rammed earth, a building material composed entirely of compacted earth that has been used since the Neolithic period.
The Rammed Earth House in Cranborne Chase, Wiltshire, is an exemplary project that showcases the benefits of this traditional construction method. The house's walls are made from unstabilised rammed earth, sourced from the grounds of the former brickworks where it was built. This approach not only reduces waste but also creates a circular construction process, where materials are gathered locally and reused when possible.
Architect Emaad Damda notes that climate change has made rammed earth an increasingly important material to consider. "The fact that our temperatures [in northern Europe] are rising means that rammed earth offers thermal mass, temperature regulation, and moisture control." The low-carbon nature of rammed earth is particularly appealing in light of the construction industry's significant carbon footprint.
However, there are also challenges associated with using rammed earth. The material's lack of consistency can make it difficult to build regulation-compliant structures, while concerns about weathering and erosion must be addressed. "The enemy of rammed earth is water and low temperatures," warns Antonio Moll, a tutor at the Architectural Association.
To overcome these issues, some architects are opting for prefabricated blocks made from rammed earth that can be transported to sites and assembled on-site. This approach reduces the need for local soil sourcing, which can be expensive and labor-intensive. Roger Boltshauser's studio, for example, has been involved in producing prefab blocks using traditional techniques.
The benefits of rammed earth extend beyond its environmental impact. The material provides a unique aesthetic experience, with buildings that blend seamlessly into their surroundings. "Materials such as glass and timber have been used to blend these structures in with their city surroundings while avoiding cement," notes Matthias Peterseim.
As architects continue to explore new ways to build sustainably, the use of rammed earth is gaining momentum. By revisiting traditional techniques and embracing local materials, builders can create homes that not only reduce carbon emissions but also provide exceptional aesthetic experiences. As Boltshauser remarks, "The more pure the material, the more sustainable it is."
