The undisputed granddaddy of the southern California architecture tour scene, Architecture Tours L.A. offers tours of hundreds of the area’s major sites, generally organized by neighborhood. Tours of the MCM-heavy Silverlake area afford the highest concentration of that area’s edifices, including Neutra’s VDL Research House II and the much-filmed Lautner Reiner-Burchill Residence. If you want a longer, more comprehensive mid-century tour of L.A., contact the company for a private tour.
