Janowa Dolina was a very modern settlement; all houses had access to electricity and plumbing and its layout was based on a specially designed grid plan. Houses were placed in the beautiful pine forest. Streets bore no names; they were marked by letters — A, B, C, D… G (Glowna — main), until the last one, Z, placed closest to the Horyn River. Along them there were houses, each designed for 4 families. As inhabitants of Janowa Dolina later remembered, the settlement was full of flowers, plants and trees and neighbors competed with each other, trying to have the most beautiful flower garden. The settlement was separated from the nearby quarry by a strip of dense forest.
