Redefining Workplace Design: HLW’s Journey Towards Healthier Workplaces With The Healthy Materials Protocol

How does our role as workplace designers transcend merely creating visually appealing and functional offices to encompass the creation of environments that promote health, sustainability, and social responsibility? To empower our team with knowledge about healthy and sustainable building materials, at HLW we introduced our own Healthy Material Protocol last year. This protocol encourages our designers to think creatively when choosing materials, explore unconventional options, and always consider the broader implications of their choices. We are interrogating material specifications, establishing baselines for embodied carbon, and replacing standard products with innovative alternatives.

We recently had a chance to put the protocol into action with the design of home improvement company Kingfisher’s London HQ. Tasked with aligning the office with the company’s forward-thinking Environmental, Social, and Governance (ESG) objectives, our primary focus was on decarbonization. This involved meticulous attention to reducing embodied carbon emissions through the entire lifecycle of the interior fit-out—from raw material extraction to disposal and recycling. Working closely with the client and sustainability consultancy BEYOND, we scrutinized every aspect of the building’s materials, resulting in a staggering 78% reduction in embodied carbon.

Additionally, our experience with Kingfisher emphasised the importance of considering the entire lifecycle of materials. For example, we are now rethinking how we integrate joinery and finishes, as well as furniture, which use adhesive in the assembly stage. These are dangerous to our health as they contain hazardous chemicals, but also to the planet as they limit the after-life potential of materials.

It also got us thinking about how we can delve deeper into sustainable practices and consider how we introduce biophilia into our projects. For HLW, this means far more than just planting.

HLW considered the 15 patterns of biophilia and which were most relevant to the brief to include within the design and enhance the connection between employees using the space and nature. For example, we provided areas of refuge, one of the 15 patterns of biophilia, with a feeling of calm and safety mixed in with unexpected details and lively injections of colour. To balance the use of the refuge spaces, the other biophilic pattern which was deemed important to Kingfisher was Prospect, HLW achieved this by providing unimpeded views along the open plan space allowing the users to plan journeys and surveil the space.

Another principle of biophilic design, Material Connection With Nature, emphasizes the incorporation of natural elements and materials in design the use of natural materials, significantly enhancing health in our office environments. By using materials that age gracefully and have a tactile, authentic quality, designers can create a more inviting and comforting atmosphere in the spaces they design. For instance, timber surfaces and furniture can evoke a sense of stability and calm, while stone elements offer a grounding effect.

At Kingfisher, natural materials like cork, plywood and timber not only bring aesthetic warmth and texture but also contribute to improved air quality and reduced exposure to harmful chemicals commonly found in synthetic materials. Additionally, they are proven to produce biophilic reactions such as a reduction in stress and cortisol levels.

HLW’s Healthy Materials Protocol aligns with these principles by prioritizing the selection of natural materials that are free from harmful substances, ensuring a healthier indoor environment. This protocol underscores the importance of using materials that contribute to both physical health and psychological wellbeing.

With the Healthy Materials Protocol, we hope to inspire a shift in how the industry specifies materials. By thoughtfully selecting and integrating natural materials and patterns of nature, and carefully vetting all materials and furniture, we can create healthier, more inspiring workspaces that support the mental and physical wellbeing of employees.
