Diary of an Eco-Builder follows environmental researcher Will Anderson as he documents the full process of designing and constructing his own eco-friendly home in the UK, from finding land and obtaining planning permission to the practical challenges of building a low-impact “zero-carbon” house. Based on his columns in The Independent, the book combines a personal diary style with practical reflections on sustainable architecture, energy efficiency, and ecological design principles, showing both the technical and bureaucratic difficulties of self-building an environmentally responsible house. Along the way, Anderson highlights real-world lessons about sustainable materials, ecological planning, and how a building can be designed to function like a living ecosystem, while also sharing contacts and resources for readers interested in similar projects.
