Wide Porcelain Tiles
These wide porcelain tiles are from a great article on engaging Asian balconies that we love.
This style could also be accomplished with wide, wooden panels but the tiles are so nice and clean that they are my favourite option.
In Toronto you're usually not allowed to change the wall colour or put up stone (who invented that stupid rule!) but you can put up a hanging or something else that gives you a more balanced look than grey concrete.
I like the two sizes of tile and the simplicity of the design. Beautiful.
