1 High Street Attleborough comprising Unit one (also known as Nan Gibbon's Cottage and the Victorian Cottage) and Unit two (also known as Acorn Cottage)

A building of 18th century and earlier origins, comprising Unit one (also known as Nan Gibbon's Cottage and The Victorian Cottage) and Unit two (also known as Acorn Cottage), it was formerly a shop, storage area, and housing. In the late 20th century, it was subdivided into six residential units.

The building is constructed of rendered brick, with interior timber framing surviving in Unit two of the cross wing. The roofs are covered in pantiles.

The building is two storeys high, with attics in parts. The main range, Unit one, runs east-west along the High Street and has a half-hipped roof. Unit two, the cross wing to the west and also known as Acorn Cottage, is similarly rendered with a gable roof. The facades feature 20th century doors and door openings, and some 19th century windows in both the main range and Unit two. The windows of Unit two have hoodmoulds. The rear of the main range is largely hidden.

The interior of Unit two was inspected and reveals 16th and later century timber framing in the front gable end. Some timbers have been reused, and some ground-floor posts have been replaced with brick piers of handmade bricks. Timber wall framing to the west elevation and partly to the east, and the frontage cross wall, remain at ground and first-floor level. A later attic ceiling includes chamfered spine beams with run-out stops. The roof structure appears to consist of common coupled rafters with collars, which are likely of 17th century or later date.

Number one A, Units three, the Old Antiques Shop, and Rogues Fair Barn were largely rebuilt during the conversion or in the late 20th or early 21st century and are excluded from the listing.
