Miniature Building Authority has new 28mm terrain available, the Farmstead (which could fill a table pretty much by itself) and some new walls.
From the release:
The Miniature Building Authority is proud to announce the release of our new 28mm Farmstead II and Farmstead wall set. As with the rest of our Miniature Building Authority products they come pre-painted and pre-assembled ready to put on the table and start gaming. The Farmstead consists of four buildings and two wall sections. The Farmstead Wall set consists of 4 straight wall sections and one gate section.
