Our mission
Structural and Façade engineering

Terrell’s assignment covers the structural engineering and façade of this major restoration and extension project on a building in Boulevard Voltaire in the 11th arrondissement of Paris. The original structure was built in the 1860s in the Haussmann style for residential use. It was later redeveloped into a 6-storey office building with two basement levels and a raised ground floor. The site will host coworking spaces from October 2018.

The existing building will benefit from a metal-framed mezzanine extension over the courtyard and the installation of a lift. On the second floor, the roof terrace will be demolished and then rebuilt in accordance with the new specification. Part of the existing gardens will be dug out to facilitate the installation of a new glazed façade at first basement level. In particular, a single-pitch skylight will be created in the garden along the party wall.

Work on the façade includes the replacement of existing wooden joinery on the Haussmann-style section, the inclusion into the existing industrial-type façade of panels with opening glazed sashes and the dressing of the mezzanine created on the third floor with a fully glazed glued structural curtain wall. All the metal profiles used will incorporate thermal breaks. A 2-storey extension will be built at the back of the plot, dedicated to coworking offices and meeting rooms. This will be metal-framed with brick cladding and sliding glass doors.

This project is targeted to achieve a rating of “Excellent” under the French HQE certification scheme and a BREEAM rating of “Very Good”.
