She has led several multi-disciplinary projects from inception to completion and now leads the practice’s dedicated team of sustainability specialists. She has structured the practice’s Whole Life Design strategy, and the development of the in-house H\B:ERT whole life carbon tool, which ensures all projects are measuring and reducing Whole Life Carbon and enhancing the architectural response to human and planetary health. She is the 2022 AJ100 Sustainability Champion, a London Mayor's Design Advocate and on the New London Architecture Net Zero Expert Panel.

Louisa is the co-author of updates to the RICS PS Whole Life Carbon Assessment for the Built Environment which is currently out for consultation.

We are on a mission to demystify sustainable design and make it effortless; collectively we can combat the climate and biodiversity crisis. Our whole life design approach reduces carbon emissions over the lifecycle of a building and creates healthier, happier environments.

We are architects, urban and interior designers and have been pioneers in sustainable design since the practice was founded 35 years ago. We constantly challenge ourselves, our clients, colleagues and competitors to do better. And we do that by investing, researching, reviewing, inventing and - most importantly - sharing the knowledge and tools we create. We have developed H\BERT (Hawkins\Brown Emissions Reduction Tool) an award-winning open-source tool for architects, designers, and clients to achieve zero carbon emissions at every stage in a building lifecycle.

We are currently working on the UK’s largest Passivhaus development and its first Passivhaus-certified hospital.
