We have similar thoughts on being ready to adopt a composting toilet, I gotta tell you lol. Those birdhouses are a fabulous little addition to the ecosystem, I love them. I too love the spectacle of a living roof, it's a fab way of using up dead space and adding some natural flora too.
This area looks like it has embraced the eco friendly message wholeheartedly and practiced what it preaches. This post and the lovely pics got me in the mood to get outdoors now we are finally out of the last lockdown in the UK.
Good to see ya man, hope you are doing great. I noticed that you tagged me on Father's day, I appreciate being remembered after such a lengthy absence, it was nice to see after quite a dark period. Look forward to crossing paths a lot more, you've always been one of the genuinely good guys :)
