Faceted, diamond-cut stonework following a curved plan.

The load-bearing stone is slanted and diamond-cut into a faceted pattern that wraps a curved plan, the first curved quad in Oxford. The geometry lets a heavy masonry skin follow a continuous curve while giving depth and shadow to the surface. It demonstrates contemporary stereotomy with traditional materials.

Faceting a load-bearing stone skin into diamond-cut angled planes to follow a continuous curved plan is a piece of contemporary stereotomy — it solves the geometric problem of making a heavy masonry skin track a curved line without resorting to either thin bent cladding or a brute-force series of straight facets by using the stone's geometry itself as the resolution. The shadow depth and surface modulation this produces in a facade is qualitatively different from flat or minimally profiled stone, and the visual richness is inherent to the material and geometry rather than applied. The practical cost is fabrication: diamond-cutting to the required angles requires CNC stone cutting and close collaboration between the structural engineer, the stone supplier and the contractor to maintain tolerance across a continuous curved geometry where each unit's angle differs slightly from its neighbour. The claim of being the first curved quad in Oxford signals genuine novelty but also genuine absence of local precedent for the construction programme, which means the learning curve for contractors and the tolerance management regime will likely be tested in real time. Without pros, cons or evidence data attached, this reads as a high-craft solution justified by its geometric context; whether the premium is appropriate depends on the institution's valuation of material longevity and contextual dialogue with Oxford's stone heritage against a significantly higher procurement and construction cost.
