Freestanding single-bay (single-bay deep) single-storey gable-fronted summerhouse, extant 1903, on a rectangular plan. Now in ruins. Pitched (gable-fronted) roof now missing with rubble limestone coping to gable to front (west) elevation. Part creeper- or ivy-covered stone-encrusted rendered wall to front (west) elevation on battered base with rubble limestone buttresses to corners; stone-encrusted rendered walls (remainder). "Venetian Window" to front (west) elevation with stone-encrusted rendered red brick block-and-start surround. Round-headed door opening (east) with stone-encrusted rendered red brick block-and-start surround. Interior in ruins with shell-encrusted walls. Set on wooded river bank in grounds originally shared with Tykillen House.

A grotto-like summerhouse not only surviving as an interesting relic of the Tykillen House estate following the sale (1955) and demolition (1957) of the eponymous country house described as 'a fine courtly mansion enviably situated on the [bank] of the River Slaney' (Lacy 1863, 466; cf. 15703748), but also illustrating the continued development or "improvement" of the estate in the nineteenth century.
