Our Story
A guest mistook our London property for a hotel. We saw no reason to correct them.
Timeline
- Land acquired.
- Shell completed.
- Champagne chilled.
- Power arriving shortly.
Values
Semper Firma.
The power is firm. The towels are exempt.
Three rules of the house. The concierge has never heard the word datacenter; he knows residences, suites, and estates. The model is the guest, and the human is the guest’s representative. Flattery in the headline, honesty in the fine print.
Leadership
Responsibility
Locally sourced electrons. Artisanal tokens.
- ElectronsLocally sourced wherever the utility permits.
- PUEDisclosed like a vintage, estate by estate.
- HeatRejected responsibly: into the fjord, the district heating network, and the former helipad.
