PURPOSE: To make an effective use of a space formed below an exterior staircase by providing an outdoor floor installed in front of a second floor entrance of a building and an exterior staircase bridged between the outdoor floor and a ground and an under staircase-wall which forms an under staircase-chamber below the exterior staircase. CONSTITUTION: An exterior staircase 2 is slantingly spanned between an exterior floor 3 and a ground GL and an under staircase-wall 5 which forms an under staircase-chamber below the exterior staircase 2 and an under floor wall 6 which forms an under floor chamber under the outdoor floor 3 are connected to an exterior wall 4 of a building. Then, the under floor chamber is effective to use the space under the exterior staircase 2 as a housing space, capable of housing such articles which are not desired to be wet with rain. Since the under staircase-chamber is accessible from both indoor and outdoor sides, it is convenient to house such articles used outdoors as a bicycle. |
