Ceiling vaults of Saint-Jean de MontmartreSaint-Jean de Montmartre[edit]Cottancin worked with Anatole de Baudot, a structural-rationalist pupil of Eug\u00e8ne Viollet-le-Duc, in the design of the church of Saint-Jean-de-Montmartre. Building started in 1897, but was suspended in 1899. The immediate reason was an infraction of planning regulations, but doubts were raised about the ability of the reinforced concrete floors and piers to carry the loads. Extensive tests were carried out, subjecting the components to extreme stress, before construction was allowed to resume in 1902, complete in 1904.The church structure is based on reinforced cement piers and rib vaults,roofed in two layers of reinforced cement separated by a 4 millimetres (0.16\u00a0in) layer of slag.The walls consist of two layers of brick separated by a 7 centimetres (2.8\u00a0in) air gap.The church is faced on the outside with orange brick.This was the first religious building to be built from reinforced concrete in France.Methodist church, Exeter[edit]  Methodist Church in Sidwell Street, Exeter, England (behind the “Duke of York” pub)Cottacin designed the Methodist Church in Sidwell Street, Exeter, England, built between 1902 and 1907.As with other buildings, the structure combined reinforced concrete and reinforced brick.The red brick wall is made of two 3 inches (76\u00a0mm) brick skins joined across a 20 inches (510\u00a0mm) cavity by reinforced diaphragms.Each brick has four perforations. Vertical wires run through these perforations, and are interwoven with horizontal wires that run through each bed joint.Inside, a gallery 13 feet (4.0\u00a0m) wide is cantilevered from three walls. The roof has an octagonal dome with 2 inches (51\u00a0mm) of reinforced concrete resting on an inner skin of reinforced brickwork.A decorative lantern tower and ventilation turret tops the dome.There are ornate moldings around the doors and windows that look like stone but in fact are reinforced concrete.Other structures[edit]  Other structures that used his system included:Restoration of floors of the castle of Blois in 1893House of Paul Cottencin, at the corners of Rue de Lonchamp and Rue PomereuFloor of the shop at 125 rue de MontreuilFloors of the Lyc\u00e9e Victor Hugo, rue de S\u00e9vign\u00e9, ParisFestival room of the caf\u00e9 GlobeFloor of the Schweitzer factory, providing an overload of 1,000\u00a0kg\/m2San Merino Pavilion for the Exposition Universelle (1900) in Paris.Road bridge in PortugalTulle TheaterMaison Bigot, 29 avenue Rapp, a fashionable townhouseTownhouse of Anatole de BaudotLa Sadikia in TunisFoundations of Enghein CasinoRoofs of the ch\u00e2teau de Rochefort-en-YvelinesReservoir of MontretoutReservoir of Deux-Portes, LouveciennesReferences[edit]CitationsSourcesAyers, Andrew (2004).
