Marrons Announces Promotion Duo

Marrons | News

Planning, design and development consultancy Marrons has announced two promotions across its planning and socio-economics teams.

Simon Macklen, head of economics, based in London, will become an equity member in legal and professional services group Ampa, of which the consultancy is part of. Matthew Roe, based in Leicester, has been promoted to principal planner.

With more than 25 years’ experience, Simon has been member of the Royal Town Planning Institute (RTPI) for 18 years. His work supports commercial developers, landowners and housebuilders in the delivery of socio-economic evidence underpinning development proposals.

Projects include economic benefit and impact assessments, demographic modelling, and socio-economic statements, which provide a robust and credible evidence base to inform and support development proposals.

Since joining the Marrons team in 2021, Simon has developed the specialist practice area including growing the team with the appointments of economics director Dan Usher and socio-economics planner Isabelle Woodville-Hill.

Matthew – who has more than eight years’ experience – works with developers and private individuals to deliver attractive, sustainable and feasible development proposals. Brian Mullin, partner and head of Marrons, said: “Our client base is ever-expanding across the country and we are continuing to unlock sites nationwide, which is testament to the invaluable experience and expertise we have here at Marrons.

“With this in mind, rewarding high performance is part of our culture, so we’re thrilled to announce Simon and Matthew’s truly-deserved promotions, which reflect their significant contributions to the team as we continue to grow as a consultancy.”
