Gasholder house

A gasholder house is a type of structure that was used to surround an iron gas holder, also known as a gasometer, in which coal gas was stored until it was needed.

There are approximately a dozen of these structures—most constructed of brick in the latter-half of the 19th century—that still stand in the United States.

Additionally, gasholder houses were constructed in England as early as 1825, although the mild climate made them less of an advantage.

A gasholder house provided a number of advantages: The gasholder house also provides economic advantage by reducing the condensation of gas in cold weather, and provided an attractive architectural element of the gas complex.

There are approximately a dozen known gasholder houses still standing in the United States, with the Troy Gas Light Company structure in Troy, New York, being one of the largest remaining structures of this type.
