Antonio Morelli, original owner and builder of the Morelli House, was the Sands Hotel's orchestra conductor and musical director from 1954 to 1971.  In this position, he came in contact with the top entertainers of the time, including the famous Rat Pack.  It has been reported that singers like Dean Martin, Frank Sinatra, Sammy Davis Jr. and Nat King Cole rehearsed in Morelli's music room at the house.

The Morelli House was built in 1959 on the Desert Inn Country Club Estates which overlooked the world-class Desert Inn Golf Course.  The Desert Inn properties were purchased by Steve Wynn in 2000 to make way for his new Wynn Resort on the Las Vegas Strip.  In September 2001, the Junior League of Las Vegas moved the house to Ninth and Bridger Avenues to save it from demolition.  The House is now a community historical cultural resource and the headquarters of the Junior League of Las Vegas.  The move and restoration of the house has been funded with the assistance of the State of Nevada Commission for Cultural Affairs and by generous community and Junior League member support. 

The Morelli House is a prime example of mid-century modern residential architecture.  Basically rectangular in plan, the overall appearance of the Morelli House is long and low, melding into the landscape.  The flat roof is covered with crushed white rock, and exposed redwood beams support the widely overhanging eaves.  In several places along the front of the building, walls are covered with stucco and screened with decorative openwork cement blocks that are topped by a row of windows. 

The home's interior is a paragon of period appointments, most of which have been kept in original condition.  The house is laid out in an open floor plan, with two bedrooms, a living/dining area, and a kitchen/family room.  In the living room, the most prominent feature is the fireplace, a raised "floating" marble-topped hearth with a massive hammered copper hood extending to the ceiling.  The kitchen represents the height of the 1950's modernity, with nearly every conceivable built-in appliance.
