A staircase is often judged from above. This one is perhaps best understood from beneath.
From this angle, the two flights of the Old Mill staircase reveal the full complexity of their geometry. The soffit flows through a series of changing curves, while the fine joint lines show how each limestone element contributes to the continuous form.
The post-tensioned engineering remains concealed within the stone. What we see is limestone, light and a sculptural soffit that appears almost effortless.
Designed, manufactured and installed by Carvero for the conversion of the Grade II-listed Old Mill near Peterborough, working closely with WGP Architects.
