Venetian architect no relation Château de Rastignac
Design influences
The Neoclassical design of the White House is based primarily on architectural concepts inherited from the Roman architect Vitruvius and the Venetian architect Andrea Palladio. The design of the upper floors also includes elements based on Dublin's Leinster House, which later became the seat of the Irish parliament (Oireachtas). The upper windows with alternate triangular and segmented pediments are inspired by the Irish building. Additionally, several Georgian-era Irish country houses have been suggested as sources of inspiration for the overall floor plan, including the bow-fronted south front and the former niches in the present-day Blue Room.
The first official White House guide, published in 1962, suggested a link between Hoban's design for the South Portico and Château de Rastignac, a neoclassical country house  in La Bachellerie in the Dordogne region of France. Construction on the French house was initially started before 1789, interrupted by the French Revolution for 20 years, and then finally built between 1812 and 1817 based on Salat's pre-1789 design.The conceptual link between the two houses has been criticized because Hoban did not visit France. Supporters of the connection contend that Thomas Jefferson, during his tour of Bordeaux in 1789, viewed Salat's architectural drawings, which were on file at École Spéciale d'Architecture.  On his return to the U.S., Jefferson then shared the influence with Washington, Hoban, Monroe, and Benjamin Henry Latrobe.
