Out in the open, in a regular garden, there shouldn't be a problem with doing a "lasagna" type layering.
A perched water table happens when fine material overlays coarser material but not when coarse overlays finer. I would have thought a lasagna garden would come in the latter category.
I'd assumed, perhaps incorrectly, from his previous posts, and also because the garden soil in this question was from "downstairs", that David was using this media in containers.
