Dating from the 1930s, The Armoury in Warninglid Lane was also used as a squash court before its owners gave it a unique makeover.
The home is being sold by Savills Haywards Heath and is set in roughly 0.76 acres of grounds.
All three bedrooms are on the ground floor and the conversion gives the property a contemporary, industrial feel with exposed brickwork, concrete wall finishes and commercial-grade laminate flooring.
