tiled buildings

Modern day buildings in Istanbul are made with lots of glass panels.  There was a day, when tiled buildings were the popular trend ...

 Here is a building tiled in blue and white.  The tiles are about 1/2 inch square, ...

 and grouted in between.

 Some buildings have designs in the tiles, which remind me of the Turkish carpet patterns, ...

 Perhaps the designs represent the patterns of the area where the builder's family is from.

And on one building, the tiles were patterned to look like red brickwork.

The tiled buildings all look to be in good shape.  No missing tiles visible from street level viewing.  And I certainly won't be going up any ladder to check the upper floors.
