  This paper is a continuation of our study of degenerations of Grassmannians
in our last paper, called linked Grassmannians, constructed using convex
lattice configurations in Bruhat-Tits buildings. We describe the geometry and
topology of linked Grassmannians associated to a larger class of lattice
configurations, generalizing the results in the last paper. In doing so, we
utilize results on the geometry of quiver Grassmannians and affine Schubert
varieties, and make comparison to the study of certain local models of Shimura
varieties.
