Francois Cousin House, French Creole cottage near Slidell, Louisiana, United States

The Francois Cousin House stands west of Slidell in eastern St. Tammany Parish, facing Bayou Liberty. Its c. 1790 core uses briquette entre poteaux walls, bricks set between posts. A full-length front gallery with chamfered columns fronts two equal rooms, with one large room behind, all heated by a central chimney with wrap-around mantels; a dormer sits above. Three rooms and side galleries were added to the rear in the late 19th or early 20th century.

Jean Francois Cousin, born in New Orleans in 1745, built the house facing Bayou Liberty between 1778 and 1790 while managing his father's lumber and brick interests on the north shore of Lake Pontchartrain. The core dates to about 1790. After the New Orleans fires of 1788 and 1794, clay from pits behind the house was made into bricks carried across the lake by six schooners.

The house is a French Creole cottage whose core walls are briquette entre poteaux, brick nogging set between posts, with a full-length front gallery on chamfered columns. Behind the gallery are two equal rooms and one large room, all heated by a central chimney with wrap-around mantels. A dormer sits above this section.

The house stands west of Slidell in eastern St. Tammany Parish, facing Bayou Liberty off the road, not in Lacombe. After Hurricane Katrina flooded it with four feet of water in 2005, FEMA and National Park Service permission to raise it came on November 13, 2009; work ran from December 2009 to November 2011.

Hurricane Katrina stripped topsoil at the site, exposing brick molds and discarded bricks from the Cousin brick business. The clay dug behind the house was in demand after the New Orleans fires of 1788 and 1794, and the company ran six schooners to carry its bricks across Lake Pontchartrain.
