Church of Saint-Jacques de la Lande by Alvaro Siza Vieira

Alvaro Siza Vieira

Alvaro Siza Vieira designed the marvellous Church of Saint-Jacques de la Lande located in Rennes, France. The church opened on the 11th of February 2018. Take a look at the complete story below.

From the architect: The church of Saint-Jacques-de-la-Lande will be the first church built in France’s Brittany region in the 21st-century. The project has been contracted to the Portuguese architect Álvaro Siza Vieira. Siza’s use of light and white concrete provide a unique ceremonial space that gently folds into the neighborhood south of Rennes, a residential area with five-story housing blocks. Siza’s main concern when designing the project was being able to integrate the church into the urban fabric. One of the hallmarks of the building is the circular shape on the second floor, which will hold up to 120 people – freeing up the first floor for social and administrative areas. The church will be inserted as a free-standing volume that adapts to the existing plan and the dimensions of the nearby buildings and spaces, extant or planned, in particular the size of the apartment block to the north. The programme is distributed across two levels by superimposing a cylinder with a 14.75 m outer diameter on a 16xi6 m square plan with a total height of 12 m.


The Parish Centre and the church are on the first and second floors respectively, with a smaller 97.2 m2 basement for the technical and storage areas. Two rectangular volumes break off to the west of this core, framing the entrance atrium and spanning the full height of the building. Another two identical quadrangular volumes lie to the east, along with a cantilevered half cylinder that emerges from the top floor. Circulation between the two floors is via a lift and two stairways —one of them enclosed— with two flights. The central part of the church has seating for 126, with access tor the disabled. A side chapel to the south contains the baptismal font, a semicircular apse (Chapel A) contains the image of the Virgin and the tabernacle, and a lateral chapel on the north side (Chapel B) contains the crucifix. A raised platform extends above chapels A and B, the base of the altar and the pulpit. The diagonal axis of the congregation area, which runs from the mam stairs towards the crucifix, defines the position of the attar. The restricted access sacristy is on the upper floor of the volume containing the lift and the enclosed staircase. A square platform is suspended above the cylindrical space of the church to control the light entering through the clerestory and hold the lighting and ventilation equipment. The sides of this square panel are parallel to the axis of the congregation zone. This church is thus lit from above and indirectly, reflecting off the ceiling and the cylindrical walls. Another two small clerestories are set above the image of the Virgin and the baptismal font. Light enters Chapel B through a glazed west-facing shaft. The church will be built using white reintorced concrete bearer walls with internal thermal insulation. The marks of the formwork used in its construction will be visible on the facades. The interior of the church and the Parish Centre will be paved with marble. The walls will be painted after instaling a 110cm high marble panel, except for the kitchen and bathrooms, where it will rise to 220cm. The pavements in the basement will have an epoxy finish and 220cm high epoxy wall protection. The exterior frames will be in wood with an aluminium finish on the outer face.
