An office where the temperature rises beyond reasonable levels in summer, where ambient noise prevents concentration, where the chair hasn’t been replaced in five years: we all know this situation. Designing a workspace that truly supports well-being and productivity is not just about placing a green plant in the corner of the table.
Since decree n°2025-482 of May 27, 2025, employers must integrate the risk associated with high temperatures into the layout of premises, with concrete measures on insulation, blinds, and access to fresh water. Office design has become a subject of prevention as much as comfort.

Heat, noise, light: the three concrete enemies of concentration in the office
When we talk about an inspiring workspace, we often think of decoration or designer furniture. In practice, the most common problems are more mundane: an overheated room in July, an open space where every phone call echoes, and harsh artificial lighting all day long.
The May 2025 decree now requires to reduce solar radiation in the premises (blinds, heat-reflective films, enhanced insulation) and to adjust schedules if necessary. We are no longer talking about optional comfort, but about regulatory obligation. In practice, this pushes for rethinking ventilation, the positioning of workstations in relation to windows, and the choice of finishing materials.

On the acoustic side, data compiled by DARES show that a closed office reduces the number of interruptions per hour by three to five compared to an open space. Solutions like happyspace.fr offer to assist in this reflection on spatial organization, taking into account the real constraints of each company.
Open space layout or closed office: the false debate to move beyond
The trend for 2026 is no longer all open space. Feedback from the field converges: hybrid layouts better address cognitive overload than large open areas. The idea is not to return to the cubicles of the 90s, but to combine several types of zones.
Three zones that change daily life
- Closed pods or acoustic booths for tasks that require prolonged concentration (writing, accounting, programming). Two to three booths are often sufficient for a team of twenty.
- Open co-presence spaces for informal exchanges, quick check-ins, and collaborative work. High tables, sofas, or benches are set up rather than fixed workstations.
- Buffer zones (library, quiet coffee space) that allow for changing posture and pace without leaving the premises.
Feedback varies on the ideal proportion between open and closed zones, as it depends on the dominant activity of the team. A creative agency does not have the same needs as an accounting firm. A common mistake is to copy a model seen elsewhere without analyzing one’s own workflow.
Natural light and ergonomics of the workstation: two underestimated levers at home and in the office
The impact of natural light on fatigue and productivity is often underestimated. Positioning desks perpendicular to windows (and not facing them or with backs to them) reduces glare on screens while maximizing light intake. It’s a simple reflex that transforms visual comfort.
For the workstation itself, a few concrete criteria make a difference:
- A screen positioned at eye level, with the top edge at eye level. A fifteen-euro screen stand solves the problem in most cases.
- An adjustable height chair, with lumbar support. The quick test: feet should be flat on the ground, and forearms parallel to the desk surface.
- An accessible and organized storage that frees up the work surface. Current files within reach, the rest in storage.
- A controlled temperature, which means in summer using external blinds or solar films, and in winter heating that does not dry out the ambient air.
These principles apply equally to a corporate office and a home workspace. Remote work has multiplied makeshift setups (kitchen table, sofa, corner of the bedroom) that generate back pain and decreased concentration within weeks.
Adapting the work environment to real uses rather than trends
A well-designed workspace does not look like a magazine photo. It looks like a place where people work without friction. Before buying furniture or reorganizing square meters, observing real uses for one to two weeks provides more reliable information than any external audit.
Who moves to talk to whom, and how many times a day? How many workstations remain empty on Wednesdays? Where do people spontaneously settle when they need quiet? These observations guide layout choices in a much more relevant way than a theoretical grid.
The trap of poorly allocated budget
We regularly see companies investing in a very stylish relaxation area (foosball, colorful bean bags) while keeping worn office chairs and neon lighting in work areas. The daily workstation deserves budget priority, because that’s where employees spend the majority of their time.
Better to have decent ergonomic seating and basic acoustic treatment (absorbing panels, movable partitions) than an expensive lounge area used for twenty minutes a day. Well-being at work is primarily about the elements we use for eight hours straight, not those we encounter while getting a coffee.
