Although understanding of the orders is very important, one must also realize that when it comes to residential architecture there is often more flexibility.A couple of observations here:
On the bottom photograph, the entablature extends over the edge of the column capitals on the side. It doesn't appear to extend over the front edge, but it clearly does on the sides. The face of the architrave, which is the lowest component of the entablature should align with the face of the pilaster below, both on the front face and side faces. If a column is used, then the architrave should tangentially align with the upper part of the column shaft.
The upper windows have segmental pediments that have missing components. A pediment springs from a cornice profile, which has a bed moulding at the bottom, a horizontal and vertical component called the soffit and corona, and the cymatium or crown moulding at the top. Therefore a pediment should also contain those same components, except that cymatium or crown moulding follows the top arc of the upper cornice of the pediment but is missing from the lower horizontal cornice. Notice that, with the exception of the crown, both upper and lower cornices have the same profile.
Here's an example (found on www.bafaloah.com via Google):
Many folk styles of the past are the product of "incorrect" interpretations of previous styles.
