We limit our commissions to focus exclusively on uncompromising, high-performance restorations of historic ruins here in Western Asturias. We only partner with clients who understand that doing things properly leaves absolutely zero room for shortcuts.
People sometimes wonder why we handle such a diverse range of trades ourselves rather than contracting them out. The reality is simple: in the remote locations where we operate, few other options are reliable if we want to get the job done right. To maintain our standards, we do the graft ourselves. That includes the groundwork, structural rebuilds, breathable insulation, lime plastering, plumbing, and electrical work. We also design and install complete off-grid solar arrays and heavy-duty battery storage, linking them directly to satellite internet to guarantee reliable power and communications, no matter how isolated the site is. When a project calls for it, we tow our mobile sawmill directly to the site for custom timber milling, and we manage all the land rehabilitation and restricted-access tree felling beyond the walls.
While our full-scale builds are strictly rooted in the north, we still support projects all over Spain. We supply natural, vapour-permeable insulation—like Steico, Diasen, and hemp—alongside commercial-grade Victron off-grid power systems to builders and homeowners nationwide. Because we use this gear every day, we back everything we supply with years of practical, hands-on installation experience.
For our clients in Cádiz and across Andalucía, we manage operations in close partnership with BioReforma S.L. This collaboration ensures folks in the south receive the same rigorous standard of natural insulation installation, delivered by a trusted regional specialist who shares our mindset.
