485 acres, planned to the metre.

The planning-grade campus layout: Fields A–F carry the 185-acre operational campus; Field G holds 300 acres for expansion, habitat and agrivoltaics. Click any zone for its specification; step the build phases; switch on the security, drainage and landscape layers.

Spatial Strategy

Key separations

GIS → SSEN substation0 km — adjacent
BESS → data halls>50 m (NFPA 855) · 100–300 m typical
Cooling plant → halls50–200 m chilled runs
Halls → site boundary200–500 m buffer
Alyth village → site centre~2.5 km

Design principles

Security by separation (BESS vs halls) · gravity-fed SUDS to the low point · cooling exhaust placed downwind of AHU intakes against the SW prevailing wind · Phase 1 operates while Phase 2 builds via segregated ring-road traffic · 3–5 m native-planted bund for screening and habitat.
