Any good anagrams for eird-house?

The name generally given throughout Ireland and Scotland to the underground buildings (which in some places are called also “Picts’ houses”) which served to hide a few people and their goods in time of war. The earth-house is a single irregularly-shaped chamber, from 4 to 10 feet in width, from 20 to 60 feet in length, and from 4 to 7 feet in height, built of unhewn and uncemented stones roofed by unhewn flags, and entered from near the top by a rude doorway, so low and narrow that only one man can slide down through it at a time. Implements of various kinds have been found in them,—such as bronze swords, gold rings, etc.
