Coastal Visitor Center: Minimal Intervention Concrete Structure

Design a coastal visitor center inspired by Álvaro Siza. Integrate exhibition spaces, cafés, changing facilities, observation decks, and walking paths into a rocky shoreline using minimal concrete interventions, preserving the natural landscape while framing dramatic ocean views. Low board-formed concrete walls following the existing rock contours, a single long ramp descending between boulders, the roof kept below the road line so the building disappears from above, sea spray and dark wet granite, hard Atlantic afternoon light, eye-level view along the ramp, 35mm lens, architectural photography, ultra photorealistic, 8K
