Beiruty Homes with External Stairs

Hamra - next to Bliss

As I was strolling Hamra street some nights ago, I came across these stairs, a recurrent undefined  architecture that got my attention back in 2005 (here, in Gemmayzé Street) and still interests and fascinates me. Except to being usually attached to the outer shell of a building, they remind me of Escher's Relativity Stairs going in all directions/ dimensions. While used in the city, this kind of stairs may also be found in villages since they help creating a sunny terrasse for every level.

Any more info or/and links are very welcome :)
