The west front, facing over a courtyard, had a five-bay centre flanked by hip-roofed wings two bays wide by one deep: this all looks like a re-working of c.1670.

[5] After Sir George's death in 1682 (or possibly 1665), the house passed to his grandson Price Devereux (1664–1740), whose father had died young.

Following the death in 1748 of his son, the 10th Viscount, the Hereford viscountcy passed to a branch of the family in Nantcribba near Montgomery but the Vaynor property was bequeathed as part of the residual estate to his executor and lawyer Robert Moxon.

380 On the left is the house of Vaynor, once the property of the Prices; but, by marriage of the heiress, in the last century, to George Devereux, Esq; was transferred to the Viscounts Hereford.

Ingleby's watercolour shows the S W aspect of the house which now looks onto a rectangular court yard at the opposite end of which is a long stable block.

[8] However, in the mid-1830s John Lyon Winder opted for a more modest scheme by Thomas Penson the Montgomeryshire County Surveyor which preserved a greater portion of the interiors of the house.

The style chosen was Jacobean, a reflection of taste changing from the austere medieval of earlier in the century towards more opulent decoration.

So on the West, transom-and-mullion windows were inserted (replacing Georgian sashes) and given pediments, big shaped gables were substituted, and a carved porch with pilasters and a strapwork crest was added, to give an E plan.

The library, whose l. part held the staircase, has a plaster ceiling and lovely woodwork to Penson's designs, excepting a mid-C17 overmantel, which has carved figures.

In the drawing and dining rooms, ceilings by Penson (the latter based on that in the long gallery at Hardwick Hall), and in the latter a fireplace carved by Henry Street incorporating C17 pieces.

The fine staircase, dog-leg, with its fluted pear-shaped balusters and bold bolection panelling, was reassembled – which might account for some crude details in the broken triangular pediments over the doorcases.
