With its simple layout and complete flexibility, Alto gives free rein to your imagination and provides you with an infinite number of possibilities. Because we always work better when our mind is free.
Alto is not just a high-rise building; it’s a place to work, live and flourish. Its only constraint is to be able to adapt to those of its occupants.
In addition to providing a flexible and balanced environment, where all generations can meet at any time of day, Alto is also a place to connect, interact and optimise your free time.
Designing a new high-rise building also means adapting
to this fast-paced world, looking at our society and
the way the working world is changing, studying our
leisure and relaxation habits, and analysing how to
enhance building flexibility to bring together a wide
variety of users.
We chose to encourage creative use of the space, to allow for a range of possibilities, while respecting, where necessary, the need for privacy; we wanted to bring an organic and flexible dimension to the space, making it easy for occupants to make it their own.
With the graceful forms of the La Défense ring
road just below, Alto’s organic shape is a welcome
contrast in an environment marked by functional, stiff
Its advantageous position at the entrance to the new La Défense business district makes its unique design all the more remarkable..
Overlooking a vast urban square and accessible via Boulevard de Neuilly, Alto is ideally located at the entrance to La Défense. Its wide forecourt provides enough space to appreciate its verticality and originality.
Its gentle curves blend smoothly into the surrounding architecturethe glazed façade appears to ripple in the light, accentuating its extremely delicate design.
Over the course of the day, the light plays on the glass
panels, reflecting a rainbow of colour.
The skin mimics the various hues of the sky, offering an unending display that changes as you move.
The building’s fluidity is reflected in its open-plan layout, allowing for flexibility in terms of the scale and use of the spaces, which are generous and generate a sense of identity. The rooftop terraces offer a breath of fresh air, high in the clouds.
« WITH ITS CURVILINEAR, FREE-FLOWING ARCHITECTURE AND A STRIKING SILHOUETTE THAT OPENS TOWARDS THE SKY, ALTO CREATES A DIALOGUE BETWEEN SHAPE AND SPACE. »

« ALTO IS THE EXPRESSION OF A NEW FORM OF MODERNITY WHERE PROGRESS MUST BE SYNONYMOUS WITH HUMAN WELL-BEING. »
Jean-philippe Nuel, Interior Designer
This fluidity is expressed in its flexible layout and the
building’s three-dimensional aspect, while the light plays
create a sense of vibrancy, stripping away the structural
On the ground floor, the cladding of the building’s core evokes movement in the form of several white petals, which incorporate functional elements while guiding the flow of visitors.
In addition to echoing the building’s exterior, these shapes also express a gentler, less aggressive modernity, and illustrate a biophilic approach in which design seeks to remain close to nature.
The canteen, which opens directly onto the lobby, and the
stairs and amphitheatre are examples of this approach.
The colour palette of the furnishings ranges from white to charcoal grey.
Digital artwork provides a touch of colour that creates a link between the two lobby areas.
It is a window on a vibrant world, creating a dreamlike and
The same concepts will be applied to the other communal spaces in Alto, in keeping with the building’s identity.
However, each space will be personalised to provide variation and to establish the diversity that will make the Alto building a truly living space, conducive to both work and well-being.
