Building Circular by Design
A gradual yet impactful shift is underway in our approach to buildings and their materials. Spurred by increasing environmental awareness and the need for sustainable practices, the construction industry is turning to alternative materials and innovative solutions to embrace circular design principles and close the loop on waste.
The industry has long faced environmental scrutiny due to its reliance on resource-intensive materials and energy-consuming processes. These practices often lead to waste, resource depletion, high embodied energy, pollution, and non-recyclability. Additionally, materials not sourced locally add to the environmental impact, a factor often overlooked. With a commitment to environmental responsibility that is integral to our design philosophy, our practice is driven to explore and implement these groundbreaking materials and construction methods.
Looking towards the earth
The process towards sustainable hospitality on each project begins with a meticulous selection of materials, focussing on those that minimise environmental impact while enhancing the guest experience. This includes incorporating natural materials whenever possible, with bamboo and rammed earth often taking centre stage in our projects, as they not only reduce environmental impact but also create a seamless connection with nature. Bamboo, a rapidly renewable resource, is versatile in its applications ranging from decking to primary construction. This choice can embrace local availability and connect guests with their natural surroundings. The organic texture and soothing colour of bamboo also contribute to a calming atmosphere, reflecting the principles of biophilic design.
Rammed earth also offers significant environmental benefits. By using minimal Portland cement compared to conventional methods, it greatly reduces carbon footprint. Employing on-site clay or soil cuts down transportation needs and aids in local soil management. Its thermal efficiency also provides natural insulation, reducing the need for heating and cooling.
On the topic of timber
Mass timber, including Cross-Laminated Timber (CLT) and Glue-Laminated Timber (Glulam), plays a significant role in most of our projects. Sourced from sustainably managed forests, this structural material provides an effective alternative to traditional steel components. Its use not only speeds up the assembly process but also reduces on-site disruption. Thermally Modified Timber, or Thermowood, is another alternative which addresses the durability concerns associated with conventional timber. This process, which involves heat and steam treatment, greatly enhances the wood’s longevity. As a result, Thermowood requires no additional surface treatments and is both cost-effective and environmentally friendly.
Printing a greener future
The exploration of 3D-printing technology for sustainable construction is another endeavour that we’re pursuing in sustainable design. Experimenting with carbon-negative, on-site printed concrete walls in various US projects is one venture in this direction so far. This innovative method simplifies logistics by cutting down transportation needs and eliminating intermediaries. The precision of 3D printing optimises material use and minimises waste, significantly reducing the construction industry’s carbon footprint and water consumption. Additionally, this technology allows for the creation of intricate and complex architectural forms, pushing the boundaries of sustainable design.
Responsible insulation
For sustainable insulation, we’ve found that hempcrete enhances energy efficiency and provides a vapour-permeable layer that regulates humidity and ensures healthy indoor air quality. Although its use is currently confined to regions where hemp is readily available, its potential in humid climates is well worth investigation, as we anticipate broader adoption as global hemp cultivation expands.
As contextually and sustainably responsive approaches become more urgent, pushing the boundaries of eco-friendly design has no limits. It is an essential practice across sectors. By honouring the unique characteristics of each site, we create designs that are not only environmentally responsible but also culturally enriching and socially beneficial. With no lack of options, every practice can shape a future where immersive hospitality experiences are both unforgettable and environmentally responsible.
