We started out in southern Spain spraying natural insulation (cork, lime, and clay), but two years ago we sold the business and moved to Western Asturias to return to our core skills.
Today, we take on remote, neglected stone ruins and turn them into warm, well-insulated homes. Phill and I do the graft ourselves from day one—taking care of the groundworks, demolition, and structural stonework, right through to breathable lime plastering, underfloor heating, plumbing, and electrics. We even tow our own mobile sawmill up to the site, so whether an original chestnut beam needs restoring or we need to mill fresh timber on the spot, it gets done right there.
Outside, we restore the surrounding land and handle complete landscaping backed by a qualified horticulturist, alongside tree felling and surgery with qualified climbers.
Alongside the site work, we still advise on historic builds and supply natural insulation across the country, but this hands-on restoration work in the mountains is where our heart is.
