The architectural studio AZC Architectes has remodelled the historic building of the current headquarters of the Congregation of the Blind Sisters (CSA) of Saint-Paul. This project is located in the heart of the 14th arrondissement of Paris.

This building, which once belonged to the French romanticism writer Chateaubriand, is being renovated in a process involving a series of phased demolitions and reconstruction focused on its two fundamental programmes, the residence for the elderly (FAM) and the canteen of the Institute of Sensory Education (IDES).
AZC Architectes proposes an intervention that maintains the axes and alignments found on the site, thus respecting the density of its initial volumes. An improved strategy for access to the complex was reconsidered while maintaining the spirit of the original house.

Mixed-use spaces are created for each of its programmes, emphasising the importance of a design for people who are blind or visually impaired, as well as for people with various disabilities or multiple disabilities.

These spaces are created with a low-cost strategy, both in terms of energy and maintenance, and the restoration of the old garden is taken as a priority.

This building, dating from 1857, takes advantage of its geometry to generate calm and friendly interior spaces, generating an interesting visual game in its rooms. Its structure is made up of prefabricated concrete walls and the use of light colors that stand out and reflect the brightness of the environment in the building is chosen.

Description of project by AZC Architectes

The Congregation of Blind Sisters (CSA) of Saint-Paul has been located at 88 avenue Denfert-Rochereau since 1857, when it was bequeathed the former property of the writer Chateaubriand (1768-1848). Founded by Mademoiselle Anne Bergunion in the mid-19th century, the “Œuvre des Jeunes Filles Aveugles” (OJFA) manages the socio-medical activities on the site.

The project was carried out in several stages of demolition, asbestos removal, and reconstruction of the two main programmes, the Congregation, the nursing home (FAM) and the refectory of the Institute for Sensory Education (IDES).

To achieve a solid and coherent result, the operation rethought the functioning of the site, the organisation of access for pedestrians, deliveries, and the fire brigade, while trying to preserve a human scale.

The distribution and division of the new buildings rigorously follows the axes and alignments historically established on the plot. In compliance with the PLU, the project is structured along the new "lanes". The project relies on the transparency of the large openings and the alignment of the volumes on the facades and roofs to ensure the peaceful interiority of the site. The architecture takes advantage of the density of the buildings, seizing spatial opportunities to frame views from the living spaces.  

The design of the facades leaves visible the construction system of prefabrication and assembly of concrete pieces, with materials that are in light natural colours. The base is materialised by the regular design of the bays, which continues the classical order of the existing buildings. The use of polished concrete facing preserves the general luminosity of the site and ensures the durability of the structure. The attic completes the upper part of the foyer, in a recessed volumetry.

The life of the homes and the Congregation, but also of the IDES and its boarding school, is punctuated by activities and events to be experienced collectively or in a personalised manner. The projected structures offer users private spaces, but also common spaces while offering the possibility of a social life.

History and value of the site: Chateaubriand, the sisters, the Congregation
The site is a piece of land whose heritage dimension is important for the city of Paris. Of the 8106 sqm, approximately 4800 sqm represent a large Protected Green Space (EVP) and part of the Chateaubriand’s house. The restructuring considers the historical past and the heritage and landscape qualities of the land.

The Congregation of the Blind Sisters (CSA) of Saint-Paul has been located on the site of avenue Denfert-Rochereau since 1857, when it was bequeathed the former property of the writer Chateaubriand (1768-1848).

Founded by Miss Anne Bergunion in the mid-19th century, the “Oeuvre des Jeunes Filles Aveugles” (OJFA), manages socio-medical activities on the site. The association has a dual purpose: to help young blind girls by teaching them to read and write, by teaching them the basics and the gestures of daily life and to offer young women who wish, blind or not blind, the possibility of taking vows and leading a religious life in the service of visually impaired people.

Over time, the missions of the OJFA have evolved, but on avenue Denfert-Rochereau, the elements that constitute its major vocation, endure. Thus, the site now hosts several entities:
 

CSA _ the Congregation of Blind Sisters, who, apart from activities with blind people, lead a religious life.
FOYER _ comprising a nursing home (FAM) and a living home, both are intended for blind or visually impaired adults mostly with associated disorders or multiple disabilities.
SOA _ the “Siege de l’Oeuvre d’Avenir”, an association that manages the activities of the site of the sisters in Denfert-Rochereau and the sisters in Bourg-la-Reine, dedicated to deafness.
IDES _ the sensory education institute, school for blind children and young adults. Boarding school for some of IDES students.
SIAM _ the integration service for blind and visually impaired children.


Restructuring the site: the city, the “Bâtiments de France”, a set of objectives
As owner of the site, the Congregation turned to Paris Habitat OPH. Feasibility studies, carried out because of the presence of the Chateaubriand house with the ABF and the “Commission du Vieux Paris”, made it possible to define the scope of the work to be carried out.

Through the OJFA, the sisters have been involved in the life of the IDES and the Foyer, and even if the structures on the site function independently today, they wish to perpetuate the richness of past links. The programme of the operation has therefore been designed to preserve these exceptional neighbourly links. To preserve the overall coherence and the skills developed in the field of disability compensation or integration of people with sensory disabilities, the programme set precise objectives.

First, the site was made fully accessible to disabled people. The cohabitation of the three entities: the Congregation, Foyer, and IDES, required the revision of the urban layout and the development of the routes used by pedestrians, school cars, taxis, and commercial vehicles.

Another objective was to increase the capacity of the Foyer from 32 to 75 rooms. This increase in surface area, which allowed the site to be opened to mixed-use and multi-disabled people, had the effect of increasing the density of the buildings on the same site.

The integration of the new buildings and the rehabilitation of the existing ones that had been preserved made it possible to create more functional spaces with low maintenance and energy consumption costs. The site benefited from careful work on each interstitial space.
One of the city's objectives was to preserve and improve the former Chateaubriand Garden, classified as a Protected Green Space. The landscapers carefully inventoried each tree and replanted diseased trees.

Architectural scale: organising density, preserving the “esprit du lieu”
The architectural project was carried out in several stages of demolition, asbestos removal, and reconstruction of the two main programmes, Congregation, Foyer, and the IDES refectory.

To achieve a solid and coherent result, the operation rethought the functioning of the site, the organisation of access for pedestrians, deliveries, and the fire fighters, while trying to preserve a human scale.

In compliance with the urban regulations, the project is structured along the new "lanes". The peaceful interiority of the site is based on the transparency of the large windows and the alignment of the volumes on the facades and roofs. The homogeneous architectural treatment accompanies the visitor's walk towards the existing garden.

While considering the recommendations of the “Commission du Vieux Paris” and the ABF, the envelope has been strictly designed. The project fulfils the requested programme, redefines the built masses and the quality of the external spaces which preserve the "esprit du lieu".

The architecture takes advantage of the density of the buildings, seizing spatial opportunities to frame beautiful views from the living spaces. The distribution and division of the new buildings rigorously follows the axes and alignments historically established on the plot.

The need to preserve the human scale and the "Parisian atmosphere of yesteryear" led to an architecture in two registers, expressed by two materials: polished concrete for the "base" at the ground floor and folded aluminium sheet for the "attic" for the upper tree levels.  

The base is materialised by the regular design of the bays, which takes up and continues the classical order of the existing buildings. The use of polished concrete ensures the durability of the structure and preserves the general luminosity of the site.  

The attic completes the upper part of the foyer, in a recessed volumetry. The design of the facades shows the prefabrication and assembly of the materials, which are in light natural colours.

Layout of the spaces: private and community living spaces
The site is designed to accommodate blind or visually impaired people as well as people with various disabilities or multiple disabilities. The spaces have therefore been entirely upgraded to meet the standards for people with reduced mobility (PRM) and have also been adapted for the orientation of people with sensory disabilities. Also, the quality of the places of movement is based on several elements such as colour identification or guidance by sound or voice.

The life of the Foyers and the Congregation, but also of the IDES and its boarding school, is punctuated by activities and events to be experienced in community or in a personalised way. The planned structures offer users private spaces, but also common spaces while offering the possibility of a social life.

An organisation by large functional units is also proposed to group similar functionalities as much as possible and avoid the multiplication of movements on the site.

The conviviality spaces, located at the heart of the accommodation complexes, constitute spaces of recognition, an intermediary between private space and the social life space. In the context of the Foyers, family and friends are received there, local activities are carried out and the team is met there. These spaces open onto outdoor areas, terraces, fitted out with hotel-type furniture. They lead to the activity areas which represent the heart of the establishment (computer, television, music garden, library).

The layout is functional and robust, with solid wood elements protecting the corners and feet of the walls. The load-bearing concrete walls are left exposed, as are the ceilings where possible.

The room is the private space, the place of intimacy. A space for rest, calm and reflection, it must be able to be personalised without becoming a place of confinement or isolation. The layout of this space is functional and pays attention to the areas of intensive use, such as the corners and feet of the walls, the cupboards, and the bathroom.

The Congregation
The 25 sisters, who employ 7 people, are organised as a congregation, and lead a religious life. They live in community, but also need individual spaces. Their living environment includes rooms, as well as many living spaces for community, meditation, and prayer. In addition, the sisters carry out a variety of activities to help the blind people who live at OJFA. They will have easy access to the Foyers and IDES spaces.

The Foyer
The 75 rooms are grouped by 14 or 12 rooms per floor. These rooms are built around living areas. This means that a resident can be close to his or her own private space and avoid long journeys.

To meet the needs of its operation, the home is organised into five main areas: reception and administration, social life and conviviality, paramedical centre, accommodation, and support facilities.

All staff have optimal working conditions and a pleasant living environment in both the professional and recreational areas. The notions of staff well-being and the functionality of the spaces remain present in all the premises. Hotel logistics are provided by external service providers: kitchen, maintenance, laundry.

IDES
This is a centre for sixty-eight blind and partially sighted children aged 3 to 20. The youngest children are cared for in kindergartens, while the older ones are educated at IDES. Twenty of them are boarders.

One of the key points, in terms of spatial organisation, is to allow blind and partially sighted pupils to be autonomous. They must be able to move around on their own as much as possible, which means paying attention to the circulation between the boarding school, the dining room, the classrooms, and the living areas.

The exterior spaces: the alleys, the garden
This exceptional site is rewritten and enriched according to the activities of its occupants, like a palimpsest. It is mentioned in the “Mémoires d'Outre-tombe” (Book 36 Chapter 1) by Chateaubriand, which his family passed on in 1857 to the OJFA de Saint-Paul.

This garden is a haven of peace in the heart of the city thanks to its enveloping vegetation, which supports the awakening of the senses, games, walks and meditations.

The renovation of this landscape heritage is based on the enhancement of the existing trees, old rosebushes, soil materials and uses. We have maintained the composition of the original design while adapting the plant palette to changes in climate and the need for controlled maintenance.

AZC Architectes is an architecture practice founded in 2001 by Irina Cristea and Grégoire Zündel based in Paris, France. The studio was born out of the idea that the exploration of architecture and its techniques could help to improve the built environment. Their interest does not lie in the invention of concepts, they have always tried to realise buildings for real life needs.

Through competitions and direct commissions, the office has worked on more than a hundred projects of varied scales and uses. Most of its built projects are intended for a wider public; sports facilities, conference halls, office and residential buildings, some of which very specifically for vulnerable populations. They also have eight metro stations under construction, four of them in Paris and four in Rennes and studies for a new station in Lyon.

Most of their work has been published, exhibited, sometimes awarded and they have often been given the opportunity to speak on issues of sustainability, diversity and innovative techniques that illustrate all their commitments.

Irina Cristea, born in Bucharest, graduated from ENSA Strasbourg in 1995 and studied architecture at London South Bank University and Bucharest Ion Mincu institute.

Grégoire Zündel, born in Colmar, graduated from ENSA Strasbourg in 1995. He is a visiting professor at ENSA Strasbourg from 2004-2006.
