Why Did Old Houses Have a Second Door Behind the Front Door?

Two front doors a few steps apart may form a vestibule. This episode explains how that small space could interrupt drafts when visitors arrived, provide a transition from street to home, and hold the weather and clutter of daily life. It also shows how to tell a vestibule from a storm door or a later alteration. Martin looks at documented preservation guidance and a historic example, then explains what to check before removing an inner door: the swing, floor, trim, weather seal, current exit needs, and how the household actually uses the entry.
