Meet the Team


Mark Pellant – Director & Architect

Mark was born and grew up in conservative Surrey but, having a Swiss mother, was fortunate to be exposed to European design and ideas from an early age. By the age of twelve he knew he wanted to be an architect and studied hard to get into School of Architecture. After 7 years training and graduating with distinction from the University of Brighton he worked for a number of internationally acclaimed, design-led architecture practices including Conran & Partners and Sheppard Robson in London. Mark gained extensive project experience in the housing, commercial, education and health sectors during this time and also later worked in Australia for Group GSA architects on the Sydney International Shooting Centre for the 2000 Olympics.

In the mid-1990s Mark spent over three years travelling overland through Africa, Asia and South America on a modern-day equivalent of the 18th century ‘Grand Tour’. Not only were these travels hugely influential in terms of exposure to alternative world culture, architecture and design, but they were a sobering experience highlighting global environmental devastation and the onset of the effects of climate change. He witnessed at first-hand glaciers retreating, severe flooding, drought, polluted seas and beaches, deforestation and wide-spread poverty.

Following this experience Mark resolved to make a difference in both his personal and professional life and in March 2000 he established his own practice – Koru Architects – with the intention of designing sustainable, low-energy buildings that would reduce carbon emissions and promote the use of healthy, natural and sustainable materials. Seven years later Mark took the opportunity to design and build his own eco house and put into practice his architectural ideals and sustainable principles to create a zero carbon home / office built from natural materials with low embodied energy. The house was awarded the RIBA Downland Prize for sustainability 2011.

Koru Architects is now expanding and yet Mark remains true to his principles to deliver thoughtfully designed, sustainable solutions to his clients. His vision for the future of the practice is to expand into more diverse work sectors such as commercial, education, healthcare and leisure and to be the leading ‘eco architects’ in the South East. Mark serves on the Architects Design Review Panel for Eastbourne Borough Council and has been a fully chartered and registered architect for over 25 years.
