Build a small, compact, and 100% symmetrical modern house in Minecraft. The total height must not exceed 15 blocks, and the total width must be around 30 blocks. All exterior walls must be made of Black Concrete. Every floor level must be framed by a single horizontal 1-block line of Red Concrete that overhangs the walls. The house must have a 3-story high narrow central block with a 3-block wide front staircase leading to the entrance. Attached to the center are two small 2-story side wings. The second floor of each wing must have a small, open recessed balcony with black stained glass panes as railings. Fill all window openings with black stained glass blocks. In the front yard, add two tiny 4x4 square water pools framed with smooth stone slabs. Minimalist grid footprint, do not upscale.
