The term vault in architecture refers to a self-supporting arched structure that forms a ceiling or roof, which can effectively create a wide, column-free space. While traditional masonry vaults transfer loads to walls and buttresses, contemporary versions are more broadly defined as any ceiling that follows the roofline, creating a high, curved interior. These modern ceilings are typically framed using materials like concrete, timber, or steel, which provide the structural flexibility to create the dramatic effect of a vault without its historical constraints. The round arch vault, in particular, seems to have been a recently favored form for its simple, elegant geometry and its ability to adapt to a variety of modern residential styles.
In preserving architecture, there are many possible approaches—ranging from treating a building as a static monument, meticulously restoring it in situ to the point of limiting public access, to more adaptive strategies that reprogram and modify interior spaces while retaining key architectural elements such as materiality and structural form. Yet one method stands apart, both in ambition and in controversy: to deliberately dismantle a building—brick by brick—meticulously label and document each part, and store it until a new site, purpose, or narrative emerges. Then, to reassemble it anew, possibly for an entirely different use. Though the original context is lost, this strategy aims to preserve cultural significance through transformation rather than stasis. This is the story of Murray House in Stanley, Hong Kong.
Originally constructed in 1846 as officers' quarters for the British military in Central, Murray House was one of the earliest examples of neoclassical architecture in Hong Kong—a unique and enduring trace of the city's colonial past. Its robust granite colonnades and symmetrical façade stood as a symbol of classical permanence. During the Japanese occupation of Hong Kong in 1941, the building's function was repurposed as the command center for the Japanese military police. It survived the war and continued to house various government departments throughout the postwar decades.
The House of No Waste Competition, organised by UNU-FLORES, is calling the next generation to reimagine the built environment for a pollution-free planet
The House of No Waste Competition (HØW) calls upon aspiring young architects, landscape architects, building and structural engineers, planners, builders, material and environmental scientists, product designers, and built environment professionals to engage in a global competition that tackles pressing issues of the circular economy and waste management in the built environment. The competition is organised by the United Nations University-FLORES, to mark the 50th anniversary of the UNU. Its Institute for Integrated Management of Material Fluxes and Resources (UNU-FLORES) is marking the anniversary with the launch of the HØW initiative, of which the competition is a central element.
