Thirdwave has two Directors who offer a wealth of practical experience in the field of sustainable development and business. They have well-established combined professional backgrounds in project management, business development, company creation, research, education and consultancy.


Courtney Hyde Peyton, Managing Director

BA (Eng Lit w minor in Arch History), 1989
Dipl. Architectural Conservation, 1993
MSc Architectural Conservation and Sustainable Architecture, 1996

As a founding Director of Thirdwave, Courtney shaped much of the focus of the company's work around built environment issues and progressed that work into the financial services and tourism sectors.

Courtney has always promoted the business case for sustainability.

Through her academic research and MSc, Courtney examined the relationship between conservation and sustainability as approaches to the management of the built environment. ICOMOS supported her argument and encouraged the publication of her report that the conservation of existing buildings and the manner in which conservation as a discipline uses materials and evolves its methodologies are at the heart of the argument for sustainable development.

A former principal of the Edinburgh Sustainable Architecture Unit, University of Edinburgh, she also taught part-time on a series of sustainable planning and design courses over several years. Prior to co-founding Thirdwave, Courtney advised forward looking developers on delivering a balance between conservation and sustainability on large scale regeneration and tourism developments in Italy and the Czech Republic.

Courtney is a regular presenter to Euromoney Seminars, Common Purpose, Royal Town and Planning Institute, RICS, architectural conservation courses and organisations and local authority groups addressing the qualitative, commercial and financial opportunities which can realised by imbedding sustainability thinking into investment, planning, design and procurement strategies.
