The house comprises the central block, with two flanking wings. The walls are of brick, externally faced with limestone ashlar. The pavilions were originally joined to the main house by corridors but these have been demolished. Both pavilions were built in the form of Greek temples and were originally surmounted by statues. The main house was of two full storeys, with an attic tier above, five bays, and a porch with Doric columns added by Bonomi. Internally, Newman records traces of masonry which indicate that the new house incorporated elements of the earlier, original building. William Coxe, in the second of his two-volume journal, An Historical Tour in Monmouthshire, published in 1801, gave a detailed description of the interior layout. The saloon, through which the house was entered, was an "oblong octagon". A “grand” staircase led to the upper floor. Either side of the saloon were the withdrawing room and the dining room. These led to the breakfast and billiard rooms, which were linked to the pavilions that housed the library and the music room, through corridors which Coxe describes as conservatories. When Coxe visited in 1799, he recorded the internal decoration as being in an "unfinished state".
