Rhys Edwards Date: ………………………………………………………………………………. ii DEDICATION In loving memory of my wonderful father, Martin Edwards, who gave me my love of design and architecture but did not live to see me complete this work, and to my wonderful UK „parents‟, Chris and Lina Fair who have always watched over me and given me so much inspiration, as well as being so generous with me – I love you both. iii ACKNOWLEDGEMENTS Thanks to my mother, Melody Edwards. Thank you for all your love, support and encouragement, without which this thesis would not have been possible. Grateful thanks to Prof. Andre Van Graan for your help and advice and seeing me through this seemingly endless journey. You will be sorely missed on campus, but enjoy your retirement. To all the interviewees, especially Mike Louw, for your time and patience. Mike, you went the extra mile to secure all manner of photographs and documents for me and it is so appreciated. I have really enjoyed exploring this project. iv ABSTRACT In the developed Western world, the need to preserve buildings, including industrial buildings, is well established, and the many charters that exist for guidance for preservation of the built environment point to the necessity of preservation. It can be posited that many of South Africa buildings with industrial architectural heritage are being lost either through neglect, obsolescence, demolition or vandalisation. At an international conference, David Worth, the sole South African representative for the International Committee for the Conservation of the Industrial Heritage (TICCIH), stated that South Africa‟s industrial heritage has been neglected by the public, by professionals and academics, and by commercial and political interests. Läuferts and Mavunganidze make the point that South Africa continues to lag behind other countries in the preservation of and declaration of its industrial heritage. The purpose of this research was to investigate if adaptive reuse is a successful strategy to preserve industrial architectural heritage in South Africa. A further aim was to investigate whether adaptive reuse can be considered sustainable or „green‟ (in terms of the UN‟s sustainable development goals).1 The research was qualitative in nature, in the form of a case study comprising the 10-year journey by architects CMAI to adapt for reuse the old Thesen Island power station in Knysna to the Turbine Hotel & Spa. As the power station formed part of a new precinct development on Thesen Island, some of the other buildings in close proximity which were adapted for reuse were also interrogated. Primary findings were collated from semi-structured interviews with a range of pertinent individuals as well as the lead architect for the project, along with own observations and an examination of documents and artefacts. Secondary findings comprised an extensive literature review on the importance of heritage and the adaptive reuse of industrial heritage buildings, particularly power stations. Power stations that generate electricity have been a feature of the urban landscape since the late 19th century. However, worldwide they have been decommissioned in the pursuit of 1 SDG no 9: Build resilient infrastructure, promote inclusive and sustainable industrialisation and foster innovation, and SDG no 11: Make cities and human settlements inclusive, safe, resilient and sustainable (United Nations, 2015). v a cleaner, low-carbon environment and changes in both power generation and consumption. These places are unique for their ability to foster an appreciation of history, an understanding of the present, and a vision for the future. From powerhouses of power generation, they can become powerhouses of social, economic and environmental revitalisation. It can be concluded that the adaptive reuse of the old Thesen Island power station in Knysna to the Turbine Hotel & Spa project was successful, and this study illustrates how adaptive reuse can be used as a strategy to preserve industrial architectural heritage. This adaptive reuse project has also had further sustainability (and socio-economic) benefits; now some 10 years old, it has preserved industrial heritage and continues to create and sustain jobs, attract tourists, and contributes significantly to the economy of Knysna and surrounding towns. As various municipalities in South Africa are currently wrestling with what to do with a decommissioned power station (Athlone power station in Cape Town) and those not functioning optimally, requiring refurbishing and currently available for sale or lease as at the time of writing (2014), viz. Rooiwal and Pretoria West power stations in Pretoria, as well as the announcement by Eskom (March 2017) that four power stations in Mpumalanga are to be closed, this research may contribute to furthering the argument for adaptive reuse as a successful strategy to preserve industrial architectural heritage as opposed to demolition. Key words: Adaptive reuse, heritage, preservation, industrial, power station. vi LIST OF ACRONYMS LEGISLATION Country National Environmental Management Act, No. 107 of NEMA SA 1998.

Adaptive reuse refers to the process of reusing an old site or building for a purpose other than which it was built or designed, according to Joachim (2002). Architectural conservation/preservation: Some authors in the literature regarding adaptive reuse use the terms „conservation‟ and „preservation‟ interchangeably. The National Heritage Resources Act, 1999, defines „conservation‟, in relation to heritage resources, to include „protection, maintenance, preservation and sustainable use of places or objects so as to safeguard their cultural significance‟. Thus preservation is part of conservation. In South Africa, the SAHRA, as the implementing body for the Act, uses the term „conservation‟ to mean „…all the processes of looking after a place so as to retain its cultural
