Steffan was a director at GMW Architects. Following its acquisition, he joined Scott Brownrigg in August 2015 and is based in the London office. Steffan has over 17 years of experience in the commercial interiors sector and is passionate about design that has people at its core, and about interiors that draw out human emotion and encourage playfulness. He loves the idea that if occupants feel good about their surroundings, they claim ownership and are proud of them. Steffan played a key role in major projects such as Network Rail's National Centre in Milton Keynes and he was lead designer for several refurbishments for Deutsche Bank. Other recent projects include offices across Europe for Discovery Communications and the concept design for DTZ's headquarters in London.
