As a plant lover I’ve always dreamed of having a home greenhouse. We had scheduled quite an extensive remodel/house addition 3 years ago and this was my chance to add the greenhouse. As I researched building and maintaining a greenhouse, I quickly learned I didn’t want to work that hard nor did I want that much responsibility with heating, cooling, air flow, ventilation, etc, etc. There was so much involved! I wanted this to be fun as I got older, not more work so I scratched the greenhouse idea and downsized to sunrooms. My contractor was extremely helpful when he learned how I wanted these rooms to function. He suggested wide sills made of concrete. He ordered the forms and poured the colored concrete in place. He troweled in a piece of plastic like handi-wrap and then pulled it out which gave the surface that leather – like texture. Here’s a close up.
