What was your vision for the Bergère project?

Bergère was developed in two stages: first, a “think tank”

phase with our Stream laboratory, focusing on research and

exploration of contemporary issues, followed by a “do tank”

phase, where this research was given a concrete form as an

architectural proposal.

One of the major challenges was to overcome the constraints of

a building that had historically been designed as a bank’s head

office, which was compartmentalised and inward-looking. We

sought to reverse this logic by opening Bergère up to the city

and strengthening its links with its surroundings.

We reorganised its vertical lines and opened up the interior

spaces where possible to improve transparency and commu-

nication, while enriching the building with a diverse range of

programmes This transformation also includes new outdoor

spaces and multipurpose amenities helping to anchor Bergère

within a more open connected urban dynamic that interacts

with its neighbourhood

Your CSR ambition in a few key points

We worked with our Stream laboratory to develop a lowcarbon

project that would reconcile heritage restoration with envi

ronmental ambitions This strategy makes a priority of using

whats already there with selective deconstruction and reuse

to limit the carbon footprint

Rather than replace the historic apertures we implemented a

strategy that combined conservation reuse and technological

innovation optimising thermal insulation while preserving the

buildings identity

Designed with sustainability in mind, the project combines

low-carbon materials, energy efficiency and urban integration,

establishing Bergère as a model of responsible regeneration.

How does Bergère meet the

needs of new users?

With a view to intensifying use and ensuring long-term resil-

ience, we have designed flexible, scalable spaces that are able

to keep pace with changes in the way people work and live.

A new central axis for distributing traffic flows means that the

basic core, now classified as an ERP (public building), can be

reclaimed, making it easier to open it up to a wide range of

visitors and enriching Bergère with a diversity of programmes.

The restaurant, conference and event space, sports hall and

media room are all part of a range of services designed to make

it more attractive and enhance user wellbeing

The redevelopment of the atrium and the addition of a staircase

will boost reception capacity and optimise the connectivity of

the spaces The twostorey garden has been redesigned as

a highquality outdoor space for the brasserie and business

centre while the installation of a Parisarium terrace on the

sixth floor affords exceptional views over Paris

How would you sum up Bergère in 3 words

Heritage living and contemporary

Architect and PCA-STREAM founder Philippe Chiambaretta

is rethinking Bergère through an ambitious refurbishment that

places the building within its historical context, reconciling

heritage, innovation and contemporary issues.
