Learning from Bishop Hill | February 18, 2021



Dear Members,


The Bishop Hill reservoir recently became “the talk of the town” when the underground structure was exposed during demolition and, with all the public attention, it’s very likely that the reservoir will now be conserved in one way or another. In our first webinar of 2021, we would like to explore how we might improve architectural conservation policies in Hong Kong by looking at other cities’ experience.


Shita Lam, who discovered the site in 2017 while doing research for her master’s thesis, will take us through the research she’s done with input from Architect Nicky Wong, founder of Hong Kong Heritage Exploration and Structural Engineer Marc Frost.


Fredo Cheung, Vice-President of the Hong Kong Institute of Architectural Conservationists will explain Hong Kong’s current heritage building grading system. Jennifer Lang, current Director of the MSc (Conservation) program at HKU, will discuss the US heritage conservation system based on her 30 years of experience there.


Professor Puay-peng Ho, Mr. Lee Chi Ming and John Raphael Miminas will join the session to explore possible strategies for further architectural conservation in the territory.


This event is supported by The Hong Kong Institute of Architectural Conservationists (HKICON)  and The Institution of Civil Engineers, Hong Kong Association (ICE HKA).

Speakers’ Profiles


Shita Lam Ka Wai 
M.Arch; M.A. (Phil); BSSc (Arch Studies)(Hons)


Shita Lam holds BSSc (Arch Studies), Master of Architecture and Master of Arts in Philosophy degrees from The Chinese University of Hong Kong, and is a Graduate Member of the Hong Kong Institute of Architects.

Lam’s research interest is concentrated on sacral architecture. During her 2018 study of urban voids in Hong Kong, she discovered the disused Bishop Hill underground service reservoir / balancing tank for which she proposed an adaptive reuse meditation space as her thesis. The reservoir subsequently gained prominent media attention in late 2020 when it was uncovered during demolition – which has since been suspended. Conservation grading by the Antiquities and Monuments Office will now be carried out while Lam continues her architectural research on the site.

Fredo Cheung is the Vice-President of the Hong Kong Institute of Architectural Conservationists (HKICON).  Before embarking on a career in heritage preservation, he worked at Leigh & Orange and, later, Ronald Lu & Partners, specializing in the design of institutional buildings in Hong Kong, Mainland China and the Middle East, and was involved in several award winning projects over the years. His encounter with heritage issues during his early career spurred his later interest in architectural conservation. Upon completion of his studies in the HKU Architectural Conservation Programme, he began to develop a portfolio of projects as a heritage consultant. Currently, he divides his time between teaching and pursuing his PhD.
