Big Apple Dreaming

Question for SCA folks on my flist: Do you have any reference material in your personal libraries or know of any that would provide blueprints or crude floor plans for medieval homes? I've been all over the 'net and find churches galore, but few diagrams of dwellings. I've gotten stuck with my writing project and really need to figure out the characters' house before I go any further and make a fool of myself. Thanks.
