A slightly lower two-storey wing extends to the west, adding three further bays to the composition, and the rear elevation is complicated by single-storey projections that suggest the building was altered and extended in stages over time. It is the kind of house that reads as a palimpsest, each addition a layer added by people who needed more space or different arrangements, though no records survive to say who they were or precisely when they made their changes.

What makes the Shandangan site quietly puzzling is the gap between what stands and what came before it. Local information holds that no trace of the original Shandangan house remains, and that a modern building now occupies its former site. This means the abandoned structure described here is not the ancestral seat of whatever family held the land, but a later replacement, or possibly a secondary building on the same estate. The original house has vanished so completely that even its footprint appears to have been built over, leaving this roofless or deteriorating shell as the only physical evidence of domestic life at Shandangan.
