Western Asturias: Full-Scale Restoration
We limit our commissions to focus exclusively on uncompromising, high-performance restorations of historic ruins. We partner with clients who understand that doing things properly leaves zero room for shortcuts.
We do the graft ourselves—covering groundworks, structural rebuilds, breathable insulation, lime plastering, plumbing, and electrics. When needed, we tow our mobile sawmill to site for custom timber milling. Beyond the walls, we provide complete land rehabilitation and restricted-access tree felling.
Nationwide: Specialist Services & Supply
While our full-scale builds are rooted in the north, we support projects across Spain:
-
National Distribution: We supply natural, vapour-permeable insulation (Steico, Diasen, Hemp) and commercial-grade Victron off-grid power systems, backed by years of hands-on installation experience.
Cádiz & Andalucía: Southern Operations
Our southern operations are managed in close partnership with BioReforma S.L. This collaboration ensures clients in Cádiz and across Andalucía receive the exact same rigorous standard of natural, vapour-permeable insulation installation from a trusted regional specialist.
