Our Team

Ian McKee

Ian McKee – BSc (Hons) FRICS FCABE

Managing Director

Ian was one of the founders of the practice in 1995 and is its managing director. In 2016 he was the chairman of the RICS in Scotland.

Ian is a chartered building surveyor with a first class academic background and a keen eye for design. He is therefore proud to lead a team of architects and building surveyors. His interests are wide ranging from the technical to the strategic. Ian is well versed in the full range of the profession having performed the full range of building surveying duties in the course of his career including project management, major dilapidations claims, building condition surveys, building refurbishment and property management. He has a particular interest and specialism in the hotel and leisure sectors.

Whenever he can Ian escapes to the countryside on his mountain bike or cycling the mountain passes of Mallorca.




Forming the first chartered building surveying practice in Edinburgh in 1985, 11 years later David led GLM to independence with the office reflecting David's lateral thinking, interest and enthusiasm for design and conservation.

With over 45 years of experience in property and construction, and being one of only a handful of conservation accredited Building Surveyors in Scotland, David brings a wealth of knowledge, expertise and inspiration to clients and the whole GLM team.

David always has at least one campaign on the go. Currently he is working with others in a concerted effort to improve the arrangements for the maintenance and repair of buildings in common ownership in Scotland. After 4 years of campaigning this topic is beginning to attract the attention of politicians of all parties in Scotland.




David joined GLM 22 years ago as a graduate from the University of Liverpool School of Architecture and subsequently qualified. He has matured to become one of the most experienced architects in his field in Scotland. Calm, unflappable, technically knowledgeable and having a deep understanding of the architecture of the past and present David is an accomplished designer who maintains the highest of standards. Although he has a strongly developed sense of design and an unwavering eye for what looks right, David is the opposite of a domineering architect. He will advise and lead when required but is always respectful of the client’s needs and ambitions.

He creates buildings that are open, warm and well-proportioned. Dedicated, passionate and unassuming, David gets things done and forms a strong bond of understanding and loyalty with clients.
