Light House
Length 40 Width 35 Height 97 17261 blocks
It's approximately 97 blocks tall (including the antenna). I think it has 14 floors, all with working lights and a large, daylight-sensor-powered light on the top floor. Even includes a hidden floor staircase! (floor lever on ground level by the stairs). Oh yes, there is a 2x2 spiral staircase leading from ground to top. Has commend blocks for teleporting to the top and bottom floors (to avoid a tediously long walk on survival mode). Enjoy!
UPDATE:
Changed top light to alternate in a circular pattern to imitate rotation.
