Building Extension
Projects that add new structures, stories, or spaces to existing buildings and neighbourhoods.
Building extension involves adding to or transforming existing structures rather than starting from scratch. This approach addresses growth, adaptation, and sustainability by working with what already exists in the built environment.
The community explores extensions across scales: from adding floors to institutional buildings and factories, to inserting new programmes into residential blocks, to designing neighbourhoods that accommodate change over time. Projects demonstrate how extensions can respect existing architecture while introducing contemporary uses and materials.
