The French firm, a/LTA studio designed a high-density project on the outskirts of Rennes, France

The building is the construction of a residential complex, where the architects have fragmented the volumes to be inserted in the triangular plot alternating high blocks from five to eight floors with low volumes and an iconic pitched roof.
a/LTA studio whithout losing the human scale and the relationships typical of small villages, designed a complex with a central courtyard as main project space, in which its different components interact in a delicate balance between privacy and collective life. The private apartments are combine with artist's studios and shared residences to create a diverse and plural community.

The architects use a recurrent material  the oxidised steel, which is used in cladding panels, in the railings of residential blocks and for furnishing common spaces.
 

Project description by Jean-Louis Violeau, sociologist

Le Cours des Arts: living diversity in Beauregard

Beauregard (beautiful outlook) takes its name from the vantage point on which it is located and which offers distant views between the valleys of the Ille and Vilaine rivers. To fully appreciate this, one need only climb to the top of the residential building located at the Southern tip of the triangle of the new Cours des Arts designed by the architect from Rennes, a/LTA. At such heights conducive to travel, the great landscape can be taken in from the back of this urban cockpit.

To build this diverse ensemble of housing units which combines a social aspect and home buying possibilities, the project management team NEOTOA bravely rose to the challenge of creating an “intergenerational housing complex”. In 2013, the architects Maxime Le Trionnaire and Gwénaël Le Chapelain came to carry out this programme with a new kind of community living in mind.

Quite a challenge, organised around a central communal courtyard, which six years later would become artists' studios and gardens as well as 119 housing units, 8 of which have “shared” spaces, between 9 and 11 sq.m. each, which really make this project stand out. Are they guest rooms, game rooms, conservatories? They are a little bit of all these things and feature bow windows about a metre deep; essentially, everything you might need to feel right at home behind these suspended windscreens.

How to recreate village life or rather hamlet life, on a block carved out of the Concerted Development Area (ZAC) plans, and all the while, abiding by the plot's density and height regulations? And without closing it off too much so as to avoid the inhabitants having to say to the outside: “Here, we don't live like you do”. Following the line drawn by the hedgerow, the opening in the landscape consequently becomes the centre piece of the project; the three constructions make it possible to free up space in the heart of the block. What is left to be done is to work on this “constructed empty space”. This is where the main stakes of the life of this future project lie.

This “constructed empty space” separates as much as it unites the buildings. And it must seek to reconcile spatially, in its own way, the constant tension that exists within us all, caught up as we are in our daily lives, between spending time with our community or with ourselves. How to organise opposite buildings and proximity will be a key issue. Even if diversity cannot exist without protecting intimacy, without establishing everyone's autonomy, and the free choice to meet up and spend time together.

The random distribution of the houses and artists' studios creates spaces evidently conducive to interaction for they break with the panoptic effect which would have been given, without their presence, to this wide open space surrounded by mounds. Too much visibility of each space could make those less favoured spaces seem like they were “being exposed” or “exposing” themselves and, therefore, become an obstacle to social interaction.

The noteworthy use of weathering steel, seemingly unusual for Rennes, highlights the key elements of the project. It has been used on the balcony handrails and houses alike. The line drawn by this specific material echoes the general design of this porous and traversable block. Could this be a new kind of phalanstery? If we also take into account the leisure room which houses communal laundry facilities, this project rekindles, in its own way, a utopian discourse and opens up a potential reconciliation with such ideals.

ALTA Architectes - Urbanistes | Le Trionnaire - Le Chapelain is a team structured around four associated architects.

Maxime Le Trionnaire and Gwénaël Le Chapelain, DPLG architects, met in 1997 at the Nantes School of Architecture. After graduating in 2004, they worked in several renowned agencies (Architecture-Studio, Block, Duncan Lewis, Stéphane Maupin, X-tu). The Monitor nominated them for the “First work prize” in 2008. In 2010, they joined forces. Since then they have been developing collaboration and continue to refine their architectural visions.  

ALTA Architectes - Urbanistes brings together around twenty employees who work on a contemporary, contextual and responsive architecture Each architectural project tends towards its own singularity, respectful of the suggested program.

In 2014 their agency won the European award “40 UNDER 40” which rewards emerging generation of European architects and designers under 40 years old.

Alain Tassot and Jean-Luc Le Trionnaire, DPLG architects, have worked together in Rennes since 1990. Rich in major projects in the different spheres related to public or private orders, they founded a/LTA Architects – Planners Agency in 2002.
