Description from record TR 35 NW 238:
No.s 13 and 15 Strand Street lie on the south side of the street, west of Three Kings Yard. The earliest surviving building on the site is the derelict stone and flint building to the rear of No.11 which dates to the 13th century (not included in this study, although pointed stone doorways in it's west wall formerly opened into the present No.13 - indicating that all three modern properties may have been in single ownership in the middle ages). The ruined range was possibly the solar block of a large complex which always had timber-framed ranges lying in front of it, to the north. The street front was rebuilt around 1500 as a range of two-storeyed self-contained shop units, with a central archway to a courtyard behind. Two rear wings, to either side of the courtyard, are more or less contemporary with the front. The east range appears to have contained further non-domestic accomodation, possibly stores or commercial premises associated with business on the quay to the north. The west wing was originally longer than at present; it may have been domestic, but the surviving part does not constitute a complete dwelling. There were certainly further rooms to the south, and there may have been a flint and stone range completing the courtyard to the south. After the Middle Ages fireplaces and first-floor ceilings were inserted, suggesting that most of the property became domestic, although part of the street front was certainly a shop in the 19th century, and is still so today.
