8. A Glass Greenhouse Full of Lavender
If you want the theme to feel lush instead of just purple, build a greenhouse. Mine is a little glasshouse attached to the side of the cottage, full of potted lavender, flowering azalea, and a tiny pond in the middle. The glass roof lets the light pour in, and on rainy days the whole room fogs up and looks like a dream. I keep my rarest purple plants here, and a small table with two chairs, because a beautiful room deserves to be sat in. It is my favourite place to hide when it rains.
