How to Makeover a Courtyard | GARDEN | Great Home Ideas 

It is a bird killer 😢

@sudahiawad4498 Charlie has used a native timber with a grain, Spotted Gum, for the fencing boards. At 2:27 mins he says, "A simple water based stain coloured in Spotted Gum." Good luck with your project!

@3506Dodge Not sure - but perhaps some aspect of building design from ye olde royal palaces. I think a courtyard is attached to a building, bounded by walls, and has a hard ground surface. Like loose pebbles, paving stones, the half timber deck shown here - but no grass. A courtyard could also be attached to a church, gallery, or commercial building. It doesn't have to be with a house. A pocketsize and narrow piece of land attached to a UK house, with grass, would be called a garden, rear garden or even a walled garden.

It's the size, lack of lawn and the amount of walled enclosure on at least 2-3 sides (not sure on the last one-could be either).

@@leafy803 In the US, a courtyard is an outdoor space entirely surrounded by a single building with access from all sides. A courtyard has to be in the middle of a building.
