How do I tell if my house is brick or brick veneer?
One way is by looking at the bond of the bricks. Your bricks are arranged in a running bond or stretcher bond, which is always one brick thick:



To be a structural brick wall it would have to be more than one brick thick, or have multiple wythes, and you would see headers, like this:



It's likely your walls are wood-framed with single-wythe brick veneer on the outside. But to really know what was on the inside, you would have to see inside them. The easiest way is to remove some outlet covers and look behind the electrical box. If you see an open void, it's a wood-framed wall. If the area around the box is completely solid, you might have concrete blocks making up the structure of the wall.

Beautiful house, by the way.
