The classic old-house vestibule in a new house: a door between outside and inside, and a door between the vestibule and the front hall. The space of the vestibule is compressed and tight, making the space of the home all the more explosive and impressive.
Vestibules were often built outside the wall of the house and were a device for creating a human scale as one approached the front door.
Which is the front door? This vestibule serves to transition from the common areas of the building to the private loft space. Clearly, the more important front door is the interior door from the vestibule into the loft.
Are vestibules inside spaces, outside spaces or both at the same time? Bringing some of the materials and colors from the exterior into the vestibule blurs the lines between inside and out.
Large doors open the vestibule to the stair hall when not closed. The scale of these double doors and opening provides a relationship between the smaller scale of the vestibule and larger scale of the stair hall.
Off to the side and forcing a series of turns to enter or leave the space, this entryway isn't closed off with another door. Big windows bring extra sunlight into the home. And the window seat makes the vestibule all the more functional.
A vestibule-like entry can be created in a house that's tight on space. A few defining columns, maybe a built-in bench and a lowered ceiling all create the transition space that eases the movement from outside to inside.
Traditional approaches aren't the only choices. Changes in floor material and ceiling height, plus a screen wall, create that subtle but clearly defined transition space.
