Lantokia Alki, Itxassou, France, project: Leibar Seigneurin Architectes


Completed in November 2024 in Itxassou near Biarritz (French Basque Country), ALKI's new headquarters brings together the production workshops, offices and showroom of this renowned furniture company on one single site.


The project embraces the contours of the land that features an over 7-metre slope in the ground thanks to the extremely efficient layout of the different areas: the production workshop is on the ground floor to ensure an efficient workflow with the car park, showroom and offices below it to make the most of a well-lit and quiet setting.


The building's architecture is based on a regular construction grid (6x6 m of reinforced concrete) and a metal truss structure to create extensive column-free spaces. Photovoltaic panels are installed on the roof to cover the building's annual energy consumption; there is very little artificial landscaping; the building is optimally compact and heating/air-conditioning are not required due to the extra insulation.This has all contributed to a significant reduction in the building’s carbon footprint, while ensuring optimum comfort for users.


Staff can enjoy the visual comfort provided by natural light controlled through a subtle balance of openings and permanent anti-glare sunscreens. An adaptive artificial lighting system can be activated as required.
