The present building dates from shortly after the fire of 1583, and is believed to have been built for Thomas Churche, a linen merchant from one of the prominent families of the town.
High Street was the home of the wealthiest townspeople in the 1580s, and the houses dating from the rebuilding form the finest examples of post-fire architecture in the town.
[1] A substantial and fine example of its type, 46 High Street features ornamental panelling, jetties and brackets decorated with carved human figures and animals.
[6][8][9] After the rebuilding, the adjacent house (now 42–44 High Street) was owned by Richard Churche's son, William, who was also in the linen trade.
[8] The first and attic floors on the High Street face are not horizontal; the noticeable dip in the centre is caused by subsidence, and was already evident in a photograph dated around 1890.
Other carvings include a nude caryatid (female figure supporting a structure) on the corner, a Renaissance device, as well as a sheep, a bear and a half-length portrait of a clothed woman.
The design uses ogee bracing, similar to that at Churche's Mansion; it is elaborated on the High Street façade with spurs.
[4] The ground floor of the Castle Street side was originally close studded with a middle rail, another expensive type of framing; this was still present in around 1883, but has since been replaced.
[4][23] 46 High Street is one of two houses built after the fire which originally used both decorative panels and close studding, the other being 3 Church Lane.
[1][2] The timber frame uses soffit tenons with diminished haunch, a particularly high-quality type of carpentry joint invented early in the 16th century.
The walls have full-height oak panelling topped with an Ionic frieze, and the ceiling has decorative plasterwork in the intervening spaces between the beams, featuring strapwork and fretting.
[26] The modern High Street still contains many other good examples of Elizabethan timber-framed buildings, all of which date from after the fire; these include the Queen's Aid House, which stands opposite number 46, and the grade-I-listed Crown Inn.
