Demolished in 1962, Mosstown House left no ruin, no shell, no gable to mark where it stood; the grass simply continues over what was once a notable building, and a visitor arriving today would find no visible trace at ground level.

What the house looked like before its demolition is reasonably well documented. Writing in 1990, the architectural historian Mark Bence-Jones described it as a double gable-ended structure of two storeys with a dormered attic set into a high-pitched roof, its entrance front running to eleven bays, which is a considerable span for a house of that period. The doorway, with its blocked surround, a decorative treatment in which the architrave is interrupted by projecting square blocks, sat off-centre along that long facade. Massive chimneystacks rose from the roofline, and at the rear of the house stood a tower-like addition, alongside a tall octagonal structure thought to have been a dovecot, a purpose-built tower used to house pigeons both for food and for their droppings, which served as fertiliser. Inside, the house retained seventeenth-century features including a carved wooden staircase. The combination of the asymmetrical doorway, the extended frontage, the subsidiary tower, and the octagonal outbuilding suggests a house that had grown in stages and accumulated its own particular logic over time, rather than conforming to any single plan.
