Foundation Anchor Block

The anchor block departs from tunnel architecture, presenting a solid square formation that grounds your habitat design. Its mass provides structural stability for stacked configurations while offering a flat basking platform for thermoregulation. The exterior showcases the citadel's foundational elements—weathered base stones and load-bearing surfaces that ancient builders relied upon for structural integrity. Without internal passages, this block delivers maximum thermal mass, absorbing and slowly releasing heat to create stable temperature gradients. The volcanic rock surface still provides the abrasive texture beneficial for nail maintenance during climbing or perching activities.
