The terrace with closing glass can form an ideal hothouse for orchids, the falaenopolis (smaller pink flower) and rain-of-gold.
That looks brilliant: you can enjoy the kitchen window to hang your own garden of spices on a line like that.
Vessels of different sizes are a great alternative to enjoy the space that is usually unused under the stairs.
Bromeliads, ferns and lily-of-peace look great in the living room! Just pick a spot near a window.
