Penny Lecture: Design with Nature

Cullinan Studio designs innovative buildings and masterplans that harness the power and beauty of nature for a better, more sustainable way of living. Buildings that connect people with nature are happier, healthier and more productive places. They’re better for the wellbeing of our communities and our planet.

Kristina Roszynski and Carol Costello, partners at Cullinan Studio, will discuss recent projects including Marlborough Sports Garden with a focus on the World Earth Day theme of Planet vs Plastics and our collaboration with London South Bank University on energy projects research.
