This farmhouse is mentioned as early as 1556 in the archives of the Confraternity of Saint-Nicolas, where it is spelled "Perbost". It is cited in 1744 in the deliberations of the City Council as a "tavern", inspected during the "wine inspection at the Bourdallat taverns". The building probably dates from the Ancien Régime, but it has been extensively modified since. It is represented on the cadastral map of 1835; the register indicates that it was then owned by Dominique Etchevers, who also owned the Houga and Bidau houses. Attached to the house, a barn with a hayloft was built in 1860, according to the date engraved on the portal's keystone. A repair in the masonry of the rear part and the construction of a ramp to access the hayloft probably date from the 1960s. The house was remodeled in the 1990s, particularly on its east elevation. This farmhouse, built above the Pessarou road, along the Lassarrade district, consists of two parts: the initial farm to the east, heavily modified, and a second part attached to the west, with a higher roof. The main elevation to the east under the gable features heterogeneous openings, in concrete, bricks, or stones. The west part opens on the south side with a round-arched carriage door with a date. The relief on the west side allows direct access to the hayloft on the upper floor.
