12×24 Tiny House Design, 2 Floors Plan

Exterior Design and Elevations

The design of the main façade, with a frontage of 12 feet, consists of a cantilevered portico that makes a corner to the right, emphasizing the main access to the house, and protecting the balcony on the second level.

The materials used in the facade design are cheap, since the portico has a stone finish, which could have different textures.

The other exterior walls of this small duplex are finished with smooth cement mortar. The warm color range uses ocher tones, combined with the black color of the carpentry frames and balcony railing.

To access the balcony, it is only necessary to open a double sliding door.
