Pamela Wackett
Director, Kohn Pedersen Fox (KPF)
A director at KPF, a global architecture practice, Pamela’s experience spans multiple typologies and scales, from the iconic Zayed International Airport in Abu Dhabi, to the adaptive reuse of an outdated office complex in London. In every project, she seeks design solutions that create a dialogue between the building’s form, façade, and plan.
Pamela constantly explores opportunities for innovation in technology, construction, and sustainability. Her projects address local needs and the potential of every site to positively impact the city. This approach and her expertise in community-focused residential design have been particularly valuable in achieving planning permissions in historically sensitive parts of Central London, where developments are designed to resonate with the quality and history of the area.
Pablo Van Den Bosch
