Jaded Houstonians have gotten used to losing architectural treasures to the wrecking ball. After all, the cavalier attitude of most Houston developers seems to be "out with the old, in with the new," regardless of the results. Even modern architectural gems risk destruction -- but not if Houston Mod can help it. The organization is on a quest to preserve the modern architecture of both Houston and Texas, using advocacy and education to spread its message. The city's newest, hippest preservation group sponsors classes, lectures, study tours and the like. Stephen Fox, architectural historian and author of the Houston Architectural Guide, is one of Houston Mod's several founders. Word to Houston developers: Just because a building is modern, that doesn't mean it's not an architectural classic. Check with Houston Mod before you call in the demolition team.
