Pink Stone Tower with a Triangular Base: Circular Cutout at the Corner

Design a City office building in the manner of James Stirling's No.1 Poultry — a wedge-shaped block filling a sharp triangular corner site, banded in pink and yellow sandstone, with a cylindrical void cut straight down through the middle and a drum at the prow like a ship. Compose alternating pink and ochre stone bands, a projecting cylindrical turret at the acute corner, a circular open courtyard cut through the centre, oversized square windows, a roof garden on top, grey London daylight, low three-quarter view at the prow, 24mm lens, architectural photography, ultra photorealistic, 8K
