I live in Llansilin. The Hand Inn is now The Old Hand Inn. Next to it is Tegfan, which I have been told was the bakehouse. The bread oven still exists. The White Lion, now The Old White Lion, has a driveway. On the other side of the driveway is Gwalia, which at some point was a cookhouse of sorts for The White Lion (so possibly also a bakehouse), although the White Lion did have a bread oven (now gone) and at least two ranges for other cooking. Gwalia is comprised to two small cottages joined together.
Nearly all the houses along that stretch of road were Inns, shops or businesses. One house looks newer (London House - the front fell off in the 1980s and was put back in brick). Otherwise all properties along here date back to 1750 or well before that) and most haven't changed much at all.
