About this blog

We’re trying to create a more sustainable home and this blog will chart our progress. Our journey started a few years back but we have no idea when or how it will end. We'll share our learnings and pose questions such as should we renovate, relocate or detonate; can a house ever be truly sustainable; what does 'sustainable' mean? Will our journey be fraught or fascinating? Come along and share your own thoughts and experiences. Jenny and James
