石材与混凝土的艺术中心：面向广场的厚墙

Design a small-town arts centre in the manner of Grafton Architects' Solstice Arts Centre — a heavy limestone and concrete mass with few but very deep openings, set against a sloping public square so the building acts as a retaining wall and a backdrop for outdoor events. Compose thick rough limestone walls meeting board-marked concrete along clean lines, one large deeply recessed glazed opening, a sloping paved square with steps in front, an Irish market town beyond, soft grey overcast light emphasising the mass, low three-quarter view, 28mm lens, architectural photography, ultra photorealistic, 8K
