This is actually an office (Pritchard Capital Partners), not a house. It is one of the beautiful homes (and others) that line the lakefront in Mandeville. They face New Orleans which is about 20 miles away across Lake Pontchartrain. In the 1800's and the early 1900's Mandeville was a resort community on the North Shore, a respite from the malaria and other diseases of the city. A steam-ferry service brought visitors by the groves until it was discontinued in 1936.
Today, the Lake Pontchartrain Causeway connects Mandeville (St. Tammany Parish) with the South Shore in Metairie (Jefferson Parish) and then on into New Orleans on the local highways.
