Our Team

WB Shiels was established in early 2015 by Chris Waugh-Bacchus and Evan Shiels. Between them, they have more than forty years experience at the cutting edge of MEP design.

The team are based at our central London studio under the watchful eye of Practice Manager, Marina Armstrong.

Our MEP designers are our engine, their design output is our product. Leading from the front, and very much aware that ‘good leaders don’t create followers, they create more leaders’, are Evan and Rob.

Evan Shiels

CEng, MSc, BEng (Hons), MCIBSE


Evan is a Chartered Engineer with fifteen years’ experience with major International consultancy practices. His broad technical knowledge and problem solving ability fuels his motivation, and his eye for detail is behind the numerous innovative schemes he has developed in conjunction with architects and designers alike.

At home, Evan is a busy father of three. All dreams of completing an Ironman have long faded, but he still enjoys the odd ride on his bike.

Rob Beales



Rob is a Chartered Professional in several disciplines and has over 20 years’ experience in the built environment industry. His attention to detail and wealth of knowledge and experience has allowed the WB Shiels company to develop its brand and work with some of the largest industry leaders on new developments within London and the home counties.

Rob is a father of three children and enjoys voluntary work in the STEM community along with charities. He also sits on several City of London Corporation taskforce groups “Skills For A Sustainable Skyline” and “Climate Action Group”.
