There is no blank canvas to start from and usually, there is a list of problems that don’t necessarily weave well into the existing building. Finding creative solutions to those problems, and weaving them in so it feels right for our clients, at the same time ensuring the spaces are well-suited to the human body and function better, is a challenge I enjoy taking on.”
