Fishpool Farm comprises of two ranges built at different times,set only 5 metres apart and now attached at an angle by a C20 single-storey brick link corridor. The front range was built in the late C18 or early C19 and it was probably intended as a replacement for the earlier rear ranget but, for some unknown but extremely unusual reason, both have survived as dwelling houses. In recent years it has been used as a dower house to Dingestow Court .

The front range (Cadw Record Number 25781) is a very simple Georgian style red-brick built house with the rear and gable ends constructed from random rubble. The West gable and the chimneys are now rendered and there is a blue-slate roof. It has a rectangular plan facing East, and an almost symmetrical two-storey, three-window facade. It has a simple segmental-headed doorway with a wooden doorcase and board door, protected by a very simple pitched canopy supported by a pair of slender square posts. It also has segmental-headed windows and at each gable is a chimney with a bulbous cornice.The gable walls have small attic windows.

The rear range (Cadw Record Number 25782) of Fishpool Farm was built much earlier, probably in the early C17. It is a house of low proportions and plain materials which, tucked away behind the C18 front range as it is, could be mistaken for an agricultural building except that it has a gable chimney and a pair of small dormer windows. It is built of mixed brown and grey rubble, unevenly coursed and with remains of whitewash. The roof is steeply pitched and covered by regularly-coursed blue slate on the front slope and corrugated sheet on the rear slope. In their book 'Monmouthshire Houses', Fox & Raglan identified it as a "Type IIB", i.e, a stone-built smaller house with a two-room plan, with attic or semi-attic. It has two-light casement windows and there is a short square rendered chimney with an emphatic chamfered cornice. There is an added workshop or stable attached to the south end. It is listed
as an an interesting example of a C17 farmhouse which, despite alteration to the openings and some remodelling of the interior, retains the essential character of a humble C17 vernacular building and for group value with the front range which is a good example of a very simple Georgian house.
