For these projects, I wanted to really appreciate the constraints of construction in masonry that prompted the beauty of Gothic cathedrals. In particular, I wanted to build some models that demonstrate the usefulness of flying buttresses. The problem with simulating masonry in lego is that the pieces stick together too strongly. The trick to these designs is that the LEGO bricks are built into 'blocks' that then fit together with smooth surfaces. From there it is all about balance.
In this piece, each 'block' is created from LEGO bricks of a single color. Blocks do not connect, they just rest on each other. The vertical columns in the middle only hold weight , they cannot handle any outward thrust from the central arch - this is visibly true because the columns are built from 3 pieces stacked up! Instead the thrust from the central arch is channelled through the flying buttresses to the sides.

This one is inspired by the Haggia Sophia, with a central elevated dome whose outward thrust is balanced by 4 domes to the sides. Each 'dome' has arches on the sides as well as diagonal arches across the center with a heavy capstone. This one is a bit hard to see in a snapshot.
cathedral.JPGThis time the real photograph shows a much more rainbow colored design than the ldr file.... this design was so huge, it pushed my lego set to the limit.
Here's a nifty octagonal dome. Note 8 column blocks, then 4 red and blue blocks, then 4 grey and yellow blocks, and then the lantern on top. The essence of modeling a dome is that each ring has to be self supporting, a horizontal arch.
