We replaced a smallish louvre window with a patio door in our bedroom and it makes me ridiculously happy. The reja is a box so I'll be able to put some plants in it. We need a blind and I would like some new bed-side lamps and we need to put stuff on the walls... but I am so pleased. The light filtering through the big trees is lovely.
When we bought the house this small, low-ceilinged bedroom was painted navy (!!) and the window had blackout material taped to it, sealing any light out. The woman who owned the house suffered from bad migraines and this was her solution. So this particular room has come a long way.
