The Hernage house was built in 1886. It was the first and the biggest store in Routt County. It had a vault that was used for the bank and the store. The store was called The H.J. Hernage Mercantile Co., one of the best-constructed enterprises of its kind in western Colorado. Henry Hernage was very widely known in the business circles. He was born in Nottingham, England on May 22 of 1851. His parents are Henry J. and Marie Hernage. In 1871 Henry came to Colorado and took up his residents in Boulder County. In 1885 he came to Yampa and started the store. The store had the first lock safe vault, which was used by the Stockman Bank.

The Hernage building is a two story white building located on Moffat Street Yampa, Colorado. The building is a white, two story, gabled roofed with a false front parapet. Originally the façade had two sash windows on the top floor and two-fixed panel storefront windows on either side of the entrance on the ground floor. The original shed was torn down and a new smaller shed was added. As you can tell from the pictures the original front doors and windows were removed and a large garage door, and a regular door was added. The siding is wooden lap. Before the building was made into a residence, there was a large shed that was built off to the side. Then after the building was made into a residence.
