Sandra Killeen

Head of Design


“Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.”

Antoine de Saint-Exupery (French writer)

As Head of Design Sandra guides and encourages the whole design team, keeping our vision for each project on track. With over 10 years experience, Sandra is responsible for developing design concepts that make deep connections with audiences.

Sandra’s background in print design, brand development and typography serves her well; with meticulous attention to detail and sensitivity for balance along with exceptional spacial awareness Sandra develops a graphic language that gives each project an appropriate and distinguishable identity and ensures spaces and finishes contribute towards a cohesive, enriching and memorable experience.

Beyond the studio

There is no ‘off’ button. As the boundaries of design continue to blur, Sandra enjoys exploring new spaces and collecting material that inspires her; from interior to environmental design; from editorial graphics to brand.

In recent years, since becoming a mum of two young boys, Sandra has found a new appreciation for the great outdoors and being active with the family. In her spare time she attends a woman-only bootcamp – a great alternative to the conventional gym.

Taking time to cook more ambitiously or slowly has become a luxury for the weekends! A way to unwind after a busy week. Trying new dishes, finding the ingredients, preparing and cooking (occasionally with a glass of wine).

Dream Interpretation Project

With vision, enthusiasm and the right team, Sandra believes most briefs can be ‘the dream job’. Work with people you like because teamwork is everything, and try to have fun.
