Our team organizes and manages every stage of the fit-out or renovation works for your workspaces in Paris and Île-de-France. We supervise all service providers and contractors to ensure the smooth progress of the works until your project’s delivery.
Office Renovation: The Works We Carry Out
Our project managers oversee all-trades construction sites. Depending on your project, we handle one or several work packages, from a simple refresh to the complete redevelopment of an open space.
Partitioning, Suspended Ceilings and Joinery
We build or remove solid or glazed partitions to create meeting rooms, private offices, and confidential spaces. We also install suspended ceilings, custom joinery, and wood fittings. Opening up a heavily partitioned floor often frees up space without the need to move premises.
Electrical, Lighting and IT Networks
We adapt electrical installations and cabling to new uses: flex office workstations, video conferencing rooms, screens, and furniture-integrated connectivity. We also update lighting for visual comfort and energy efficiency.
Air Conditioning, Ventilation and Thermal Comfort
A new layout of spaces requires revisiting the HVAC system: air supply, return air, regulation, and ventilation for meeting rooms and phone booths. We plan for these adjustments from the design stage, as this is one of the most significant cost items in the budget.
Flooring, Paint and Acoustics
We install flooring suited to each area (carpet, resilient flooring, parquet) and carry out painting and wall finishes. We also address acoustics with absorbent panels, phone booths, and concentration pods.

Plumbing, Restrooms and Communal Spaces
We build or renovate restrooms, including accessible facilities for people with reduced mobility, as well as kitchenettes, cafeterias, and break areas. These spaces have become central to today’s offices.
Furniture, Décor and Signage
The works are often accompanied by the selection of furniture and décor: reusing existing pieces, second-hand furniture, local manufacturing, and brand identity integrated into the spaces.

Light, full, or turnkey renovation: which project for your offices?
Refresh
Paint, flooring, lighting, and minor partitioning adjustments: we modernize a floorplate without touching the networks. This is the shortest format, often feasible in an occupied site. France Digitale had its 150 m² refurbished in one month.
Full renovation
The floorplate is overhauled as a whole: space reconfiguration, upgrades to technical work packages (electrical, HVAC, plumbing), acoustics, and compliance. This is the case with the Castiglione project, an entire floor fully refurbished in a historic building near Place Vendôme.
Turnkey fit-out (Design & Build)
Design, space planning, works, furniture, and team support are brought together under a single contract. This is the option chosen by Brevo, Vestiaire Collective, and Heetch for their new Paris headquarters.

How much does an office renovation cost in Paris?
The price of an office renovation depends on the surface area, the initial state of the premises, the level of finish, the scope of technical works, and the building’s constraints. Here are the price ranges we observe on our projects:
| Project level | What is generally included | Indicative price |
|---|---|---|
| Basic | Simple partitioning, floor and wall coverings, basic electrical network | €300 – €500 excl. VAT/sqm |
| Standard | Collaborative spaces, glazed partitions, ergonomic furniture | €500 – €900 excl. VAT/sqm |
| Complete | Space redevelopment, overhaul of technical networks, IT | €900 – €1,500 excl. VAT/sqm |
| Premium | Bespoke design, acoustic pods, high-end materials, IT | €1,500 – €2,500 excl. VAT/sqm |
Indicative ranges observed across our projects. The exact price is set after a site visit to your premises.
As an example, a 200 sqm project represents a budget between €60,000 excl. VAT (basic) and €400,000 excl. VAT (premium).
In the capital, several factors can drive up costs if they aren’t planned for in advance:
- site access: floors, elevators, deliveries;
- hours imposed by the co-ownership association or landlord;
- constraints of older or high-rise buildings;
- work carried out in occupied premises, which requires phasing.
To keep the budget under control, three levers are effective:
- reusing existing furniture (Shiseido reused 90% of its furniture);
- turning to second-hand furniture;
- entrusting the project to a single contractor, which reduces intermediaries and unforeseen issues.

Renovating offices on occupied premises, without stopping operations
Many companies choose to renovate their offices rather than relocate. It’s often faster and more cost-effective. In this case, the work needs to be organized around your teams:
- phasing floor by floor or zone by zone;
- noisy work scheduled during off-hours or closure periods;
- securing sensitive areas (reception, server room);
- regular communication with employees.
For Shiseido, we renovated 8,500 m² in 7 months, floor by floor, without any interruption to operations, thanks to genuine engineering of team movements. Rather than relocating, opt for the redevelopment of your offices.

Questions about office renovation with Les Batisseurs
How long do office fit-out works take?
On our projects, the work lasts from one month (150 m²) to seven months (8,500 m² on occupied premises). For a floor of 600 to 1,800 m², you should generally expect around three months of work, plus the design and administrative phases.
Do you have to move out during the works?
Not necessarily. We regularly organize projects on occupied premises, carried out in phases, with noisy work scheduled during off-hours. Shiseido, for example, kept its teams on site throughout the renovation of its headquarters.
What’s the difference between office fit-out and renovation?
Renovation upgrades existing premises: finishes, technical networks, compliance with standards. Fit-out organizes the spaces and equips them: space planning, partitioning, furniture, decoration. Most projects combine both, which our Design & Build approach allows.
Do you need authorization to renovate offices?
A purely interior fit-out generally does not require a permit. A prior declaration or a permit becomes necessary if the works affect the façade, the structure, or the floor area. In an ERP (building open to the public), a work authorization is required. Approval from the landlord and the co-ownership association must also be obtained.
Can office renovations be carried out in several phases?
Yes. The project can be divided by floor or by zone, which helps maintain operations and spread out the investment by addressing priority areas first.
Can existing furniture be reused?
Yes, and it’s one of the first ways to cut costs and reduce carbon impact. We repair, transform, and clean existing furniture, and supplement it with second-hand pieces or locally made furniture.
Are there any grants available to help finance office works?
Depending on the project, several schemes can reduce costs: regional grants for modernizing premises, subsidies related to accessibility, support for energy transition (lighting, insulation, air conditioning), or leasing for furniture.
Do you work outside of Paris?
We primarily operate in Paris and Île-de-France. We can also support companies in other regions depending on the project.
