Beautiful effect! It looks like they just sell it in one size. I wish the closeup showed a better view of how it's installed at the base. I'm assuming they sunk the bottom two in deeper than the top one to form the tier... but by how much? The top height is 8 feet before you sink it in at all... so would that make the clearance of the bottom one only about 6 to 6-1/2 feet? With roses on it, my son and hubby wouldn't be able to walk through it! =P
