In the kitchen remodel shown here, the post was the outside corner of the original house. The second floor, attic, and roof were held up in this corner, especially after we cantilevered the kitchen 2' out and added a new beam where the outside kitchen wall used to be. The new beam is in the ceiling just to the right of the down lights, toward the window in the photograph.
So the post became part of the design: we added molding to create a plinth block below and a column above. The 'we' in this case was me designing and the excellent finish carpenter executing.
While the kitchen and the eating area needed to be connected visually, those eating did not need to see the dirty dishes in the sink. So the back splash was wrapped around the end of the counter and tied in, visually, to the post by molding. That extra 6" keeps the sink hidden from those sitting at the table. That 6" also ties the column into the design, it isn't hanging out there alone at the end of the counter.
The kitchen table (out of sight under the wrought iron chandelier) is visible from the kitchen. So is the door to the back yard and the stair to the play room above the garage. A Good Thing for mothers and families.
A note about that window over the kitchen sink: The house sits on a hill. The view from the sink is wonderful, into the trees. The client wanted the window to come down to the counter.
The contractor - who had years of experience and much skill - did it, but it is not a good idea. Wood, glass and granite move at a different rates. Yes, houses move. Not allowing room for expansion and contraction, expecting the window frame to meet up precisely with the granite counter top is asking for problems.
