Stephen’s area of expertise and research interests are sustainable design, supporting empowerment for community projects, and placemaking. An understanding of context in the broadest sense, underpins this approach, from understanding the values, community and physical fabric of a place.

These interests are evident in recent projects that include Magdalen College Library, Oxford, the British Academy, the Enterprise Hub for Royal Academy of Engineering, Lambeth Palace Library and Pallant House Gallery.

Stephen taught a Design Studio at the University of Cambridge for five years, based on public buildings. He was a partner to the Empowering Design Practices research project with the Open University that explores our understanding of, and the transformation of, Places of Worship.

Hilary Taylor Landscape Associates specialised in research, conservation, restoration and sustainable development of major historic places, including World Heritage Sites, deer parks, public parks, allotments, and churchyards. Outcomes included planting schemes, arboricultural and ecological plans, improvement of land-use, soil structure, and drainage, renewal of waterbodies, views, vistas, and circulation patterns, new and restored landscape features, from hermitages to fountains, visitor centres to bandstands. Critical to success were management and interpretation plans.

Professor Tarek Teba

Dr Tarek Teba is an Associate Professor in Architectural Heritage at the School of Architecture, Art and Design, University of Portsmouth and the Chair for ICOMOS UK Digital Technology National Committee. Tarek is the Course leader of MA Architecture: Building and Heritage Conservation and the co-chair of the University of Portsmouth Heritage Research Hub.

Tarek’s experience in heritage valuation, sustainable development and adaptive reuse has been developing through practice and research activities, establishing national and international networks and activities around the conservation of architectural and cultural heritage, and community engagement. His contribution to the field is demonstrated in linking theories to practice to develop sustainable regeneration solutions for the heritage context, as well as in bringing together academics and professionals to promote conservation and regeneration debates.

Tarek’s research concerns the conservation of tangible and intangible heritage through creating the balance between contemporary values via community engagement and historic, aesthetic and cultural values. Tarek explores methodological approaches to preserve the cultural and contemporary social values embedded in heritage assets and cities, informing regeneration and adaptive reuse strategies. He uses community engagement and cultural mapping as an informing tool, and virtual modelling and digital heritage approaches as a vehicle to deliver adaptation and development strategies.

Zac Tudor

For the past 22 years Zac has worked for Sheffield City Council's Regeneration Design Team. Here he has had responsibility for city-wide design and coordination of public realm delivery within the placemaking agenda. His focus has been landscape design, spatial master planning, and place-making, helping to maximise the city’s resilience to flooding and climate change, while encouraging new economic regeneration that reflects Sheffield’s distinctive historic character.

He has established himself as the key influence in developing Sheffield's identity as a city of distinctive high-quality public realm promoting its uncompromising sense of place and character. His use of horticulture, local natural materials, craftsmanship and art helps to draw on local heritage to create something that is identifiably Sheffield.

Today his interests turn to the re-purposing and changing perceptions of city as a place, identifying character and maintaining and emphasising the historic value, which when combined start to create new incentives to live, work and visit our urban centres.
