Greenelle, Paris

Modernisation of an obsolete block into a green office building in Paris

The backdrop

Greenelle is a 14,000 sqm office building located close to the Eiffel Tower in the centre of Paris. Acquired by InfraRed in May 2014, the asset was in poor condition and about to be vacated by its single occupier, Hachette Publishing. Despite this, InfraRed believed the location to be particularly attractive thanks to numerous on-going major urban regeneration programmes.

We stepped in to acquire the site, securing the opportunity with a creative business plan aimed at repositioning the asset and achieving its full potential through a significant, sustainable green refurbishment programme.

The challenges

The key challenge was to undertake a major upgrade to the existing building frame, transforming an obsolete 1970s office block into a contemporary Grade A workspace delivered to high environmental standards whilst remaining within existing planning constraints. 

Beyond the technical complexities, InfraRed also managed to mitigate and resolve a range of issues, including planning consent and title regulation. 

Creating spaces to inspire peoples' lives

Cutting-edge technologies developed for the project included a climate-control system based on geothermic innovation. Innovative design also made it possible to retain the building's core while replacing the cladding with a brand-new energy-sufficient facade. 

The building was awarded three different green certifications (HQE, BCC & BREEAM), which proved to be a decisive factor in attracting new tenants. Our focus on sustainability provided the building with a competitive edge allowing us to lease up the majority of the space to a blue-chip industrial company before achieving a successful exit in December 2016. 

"This project has given a new lease of life to a prominent but obsolete office tower in a well-known city-centre location. It is an excellent example of how InfraRed contributes to urban regeneration to the benefit of multiple stakeholders." Andreas Katsaros
