One of the hallmarks of an owner-built home is the presence of labor-intensive ecentricities such as this wonderful stone and bottle entranceway. The owner most probably found the rocks in the arroyo next to his property. They certainly look the same as the ones in the top picture. As for the bottles set in mortar that form the parapet, there is no reason to assume that the owner acquired them when they were already empty. This re-use of materials, and the adaptation of old materials to new uses, puts the owner-built house at the forefront of the recycling movement...even though it was probably necessitated by a lack of money.
