Joint program associating tertiary and residential buildings :
Reconstruction / Requalification of the historical site of 'Vachon Antiquités', including residential housing units, social housing, offices, and a company restaurant on the ground floor
Offices and housing are delivered at 129-131 Avenue Paul-
Vaillant-Couturier in Gentilly, where 'Vachon Antiquités', a
family-owned company founded in 1951, rent furniture and
sets for theatre, film, television and events until a fire ravaged
its depot in 2011. In practical terms, the site represented a
massive 4,000-square-foot warehouse on four floors. We can't
list all the merchandise that was used for filming; just a few
examples: "La fumerie" in Marco Ferreri's La Grande Bouffe,
"Le salon Régence" in Roger Vadim's Les Liaisons dangereuses,
and "Les casiers" in the series Les Cinq Dernières Minutes.
Gentilly commune renews the real estate offer to create a
sustainable territory, to revitalize its economy. The developer
Lamotte Construction has appointed WAW Architects and
SLA Architecture to design a mixed operation combining
tertiary and residential areas. The architectural response
develops modular and qualitative office spaces, complemented
by a company restaurant on the first floor, housing units and
social housing units facing the garden. The chosen design
inserts these complementary functions with transparency and
sobriety, which are crucial to the life of the neighbourhood.
WAW Architectes and SLA architecture's project adapt to fit
the configuration of the site and its environment. It allows
the reduction of nuisances, a virtuous economy and the wellbeing
of residents.
L'ATRIODE & LE SAND
AT THE GATES OF PARIS
Gentilly, a municipality in the first ring of suburbs located
closest to Paris, has always had a dual identity, both
residential and economical. Its boundaries are defined
by the strong presence of transport infrastructures in
the immediate vicinity (RER B, A6 freeway linking to the
southern Paris ring road), or close by (external boulevards,
tramway and La Porte d'Orléans less than 700 m away).
This office program is part of an overall operation of 9,970
m sq, grouping activities and housing in a mixed urban
process, located both in the heart of a heterogeneous
urban fabric and facing the ring road. The project gives
the perception of a building composed of two volumes:
To the north of the site, on the Avenue Paul Vaillant
Couturier, the building in R+5 - whose last level set back
- offers a template commensurate with an urban context
where the large scales are mixed. A building front is formed
on the boulevard, facing the ring road, playing on subtle
shifts of bays from one level to another, and the nature of
the glass, alternating transparency and translucence, thus
revisiting the traditional facade of a tertiary building. The
style is enriched by various architectural events such as the
recessed attic, the double-height canopy of the entrance hall.
To the east, on rue Dedouvre, the building, aligned on the first
two levels, offers a mineral façade in keeping with the context.
The levels are then set back on the upper classes, keeping with
the surrounding urban template and developing the same
façade register on Avenue Paul-Vaillant Couturier.
VOLUMES BÂTIS
ET ENSOLEILLEMENT
Despite the density of the operation, the volumes and
templates of the proposed block sculpt the orientations and
sunlight of the plot: the templates of the buildings draw two
significant openings: one breakthrough to the east and the
second to the west, for sunshine from morning to evening.
A VEGETATION
DEPENDING ON THE USE
The operation integrates a variety of vegetation spaces
according to their location and use:
- In the heart of the block and on the ground floor
- On the terraces of the office buildings
- On all "5th façades" through the treatment of green
roofs (allowing to satisfy visual comfort of the
neighbourhood and and to improve rainwater
retention)
SYNTHESIS OF PRIVATE
AND PUBLIC INTERESTS
This operation is, first of all, an efficient negotiation between
the municipality of Gentilly and the company 'Vachon
Antiquité', both owners - in part - of the parcels that have
gone up in smoke. WAW Architectes carry out valuable
work analysing the Local Urbanism Plan (PLU) and all the
consultations between the public and private to guarantee
their interests in the project's success.
URBAN
INTENTIONS
The immediate environment comprises small apartment
buildings and single-family homes of old construction,
with some shops and services on the first floor.
To the south, the environment is composed of the "Le
Chaperon-Vert" neighbourhood, a complex of more than
1,500 social housing units of approximately 11 levels.
Therefore, the project is part of a more extensive
development operation under public control. The City
of Gentilly summarises the main orientations in a
Sustainable Development Project (P.A.D.D.). The latter
defines, in compliance with the objectives and principles
outlined in the urban planning code, the development
guidelines adopted for the entire municipal territory:
- To sustainably improve the living environment
- Promote the influence of Paris
- Stimulate job creation
- Reduce inequalities
The Gentilly's Paul Vaillant-Couturier sector, within the
framework of this P.A.D.D., becomes the central axis of
economic development. Thus, the development of this sector
became twofold: to be the centre of gravity of the municipality
by symbolizing an opening towards Paris and promoting a
transition towards the social housing district of 'Le Chaperon
Vert'. The rights-of-way must then constitute new pedestrian
and cycle routes that will enrich the existing road network.
THE HEART OF THE
PROGRAM, AS AN ISLAND
SEEN AS A LARGE GREEN
WINDOW
The dimensions of the heart of the block allow for vegetation
composed of tall subjects. The distance between the southern
facades (office building) and the northern fronts (residential
building) introduces an amplitude, thus avoiding the
inconvenience of facing each other. In the same logic, the
natural lighting in the heart of the block is privileged. The
architects design the structure templates to let natural light
penetrate, particularly to the south and west. This breathing
space avoids any feeling of a gap in which the sun would not
penetrate.
ARCHITECTURAL
INTENTIONS
A JOINT OPERATION
THOUGHT GLOBALLY
Around this heart of the block are articulated two programs
that can be read in urban terms - in terms of built volumes -
as three different sections. Each one fits into the street scale
it faces and responds to the character of the constructions
surrounding it. Through the templates it proposes, this project
considers the current urban fabric and a medium and longterm
state of the urban fabric of Gentilly, which will tend to
densify. Thought of as an anticipation of the municipality's
future development and not as a short-term solution.
OVERALL COHERENCE
AT THE ISLAND LEVEL:
RELATIONSHIP BETWEEN THE
FACADES OF THE DIFFERENT
PROGRAMS
Although these are two programs for distinct occupations
and uses, WAW Architectes investigated to achieve overall
harmony in the design and shaping of the templates and the
expression of the facades. Thus, to avoid the crushing effect
and predominance of the office building on the housing
building, to emphasise the perception of a coherent built
whole, the architectural writing plays on several points; a
rhythm, writing of the facades and the breakthrough. This
writing plays on the recurrence of a vertical grid expressing
both on the fronts of offices and housing. At the same time,
several materials counterbalance homogeneity. The facades
harmony contributes by numerous glazed patios, including
multiple visual openings towards the heart of the block,
contributing to the whole balance.
