Opening a corner in a department store: what the landlord really asks for

IDEM team · 29 September 2026

A corner in a Parisian department store looks like a small project. In reality it is a worksite inside a building open to the public, with a landlord that has its own rules, an independent technical inspector and deadlines that do not move. This is what we have learned developing detailed design and building services for luxury brands in Paris.

The landlord brief comes before the concept

Every department store hands the brand a detailed technical brief: permitted finishes, loads, heights, materials, how to connect to the building's services. The brand concept has to be translated into these rules from the detailed design stage. Discovering them on site means reservations, delays and costs.

Power, climate and connections: working with what is there

Electrical power is allocated by the store and rarely negotiable. Lighting, windows and digital systems must be sized within that limit, with a load balance checked at design stage. Climate control almost always comes from the building's central plant, with chilled and hot water feeding local fan coils or coils: our job is to integrate them into the joinery without losing airflow or silence.

Fire safety: the real exam

Department stores are type M public buildings under the French fire safety regulations for buildings open to the public (arrêté of 25 June 1980). Every change must interface with the existing safety system: detection, sprinklers, smoke extraction, signage. The safety notice and the works authorisation are reviewed by an independent bureau de contrôle, as well as by the store technical team.

Working at night

Noisy works and deliveries take place outside opening hours, with restricted access and teams coordinated to the minute. A realistic programme accounts for these windows from the bid stage, not afterwards.

Documentation in two languages

Local contractors, the bureau de contrôle and the store project management work in French; the brand and often the architect in English or Italian. This is why we produce bilingual drawings and technical notes, with consistent terminology all the way to the as built file.

The result that matters

For the projects we have delivered in Parisian outlet villages and department stores the goal is always the same: open on the agreed date, with no technical reservations from the landlord. It is only possible when architecture, services and safety speak the same language from day one.
