A student of François Debret, Brunette began his career as an inspector and architect engaged in the work on the courthouse of Reims.

He built the churches of St. Andrew, St. Thomas, the vocational school, the retirement home (later demolished), the Manège and Circus and the Armory.

[1] Among his principal works were restoration of the Church of Saint-Jacques in Reims, the restoration and the enlargement of the general hospital and of the Hôtel de Ville; the construction of a covered market, several communal schools, the Church of Saint-Thomas, the Chapel of Saint-Marcoul, the infantry barracks, the gendarmerie barracks, five city gates in Reims, the office of measurement and conditioning of wool, several churches in the department of Marne and the seminary.

With his son, Ernest Brunette, he built, from 1863 to 1880, the facade of the Town Hall overlooking the street of Grosse-Écritoire.

On April 11, 1855, he received the Order of St. Gregory the Great and, on August 11, 1858, he was appointed Knight of the Legion of Honor.
