Now permanently based in Western Asturias, ECS is a no-nonsense insulation, water, and energy consultancy. We don’t just advise—we restore historic stone architecture and transform overgrown land into self-sustaining, irrigation-free environments.
We avoid standard grid-tied setups, specialising in 100% off-grid solar and battery arrays engineered for absolute power independence. Using this existing infrastructure, we are actively developing a private Virtual Power Plant (VPP) network to turn surplus yield into a financial asset.
For building envelopes, we have no time for synthetic shortcuts. We use natural materials such as cork, hemp, wood fibre, clay, and lime to create breathable, damp-free, and fully energy-autonomous homes.
Beyond our bespoke Asturian projects, we supply premium natural building materials and off-grid hardware directly to constructors and self-builders across Spain. BioReforma SL has taken over the insulation projection team and restorations in Cadiz.
We only supply what we’ve personally tested and lived with, giving you the expert guidance required to escape the chaos of modern life and live in total comfort and autonomy.
