The busy people at Castleton Homes are active at 48 Donlea Dr., having knocked down the two storey house shown at the right and as photographed by Google. Castleton does nice work. Neighbors will by now know just how high up this re-build will go. Note the surviving walls, including that of the garage. Frequently, although we do not know it in this case, walls are left standing to ensure that grandfathered aspects of the original construction are not subject to the current building code. It is a common practice.
