Isospace

Isospace is a French general contractor (contractant général) specialising in the design and fit-out of professional spaces. Founded in 1997 and headquartered in Boulogne-Billancourt in the Hauts-de-Seine department west of Paris, the company describes itself as covering the full spectrum of space management — from design and architecture through all-trades construction works to furniture, decoration and even material recycling. Its stated purpose is to design inspiring places that elevate daily life, inspire the future and reflect the ambitions of companies and brands, combining design, functionality and environmental responsibility through an integrated expertise. The company works across four main space categories. In offices it handles moves, reorganisation, renovation and equipment, providing design, all-trades works and furniture through a single point of contact. In retail it fits out shops and boutiques, from corners to flagship stores and pop-up stores, including bespoke joinery, works and opening preparation anywhere in France. In hospitality it fits out hotels and restaurants — rooms, reception areas, dining rooms, common areas and terraces — from design to delivery. A fourth activity, Isospace Brands, focuses on showcasing products and brands through bespoke furniture design, visual merchandising, shop-window fitting and decoration, as well as stands, displays and point-of-sale advertising, with particular renown in airport zones. Isospace positions itself as a general contractor operating on surfaces from 150 m² to 10,000 m², from open-plan offices to corporate headquarters. It reports having delivered more than 3,500 projects since 1997 and employs around 60 people. Its integrated model is presented as an alternative to a market dominated by large players and standardised approaches: the company argues that businesses now seek hybrid, flexible and embodied spaces that translate their culture and real uses, and it emphasises the power of the singular, bespoke project. As a general contractor it avoids resorting to an external project management team, offering clients a single point of contact, a single quote and a single schedule. Its service range covers on-site audits, 2D plans and photorealistic 3D design, moods, furniture and finishes, followed by all-trades works — demolition, partitioning, electrics, air conditioning, painting, flooring and ceilings — and the installation of professional office furniture. The company highlights its ability to work in occupied premises so that clients can remain operational during works, and it cites CSR certification. It also operates a 600 m² workshop in Bry-sur-Marne where artisans produce bespoke joinery, lighting and glasswork, large-format printing, adhesive lettering and logotypes, and film decorations. Isospace's client base spans SMEs and large groups, and its Paris office fit-out activity is presented as a specialism in its own right, addressing the specific constraints of the capital: Haussmann-style buildings with mouldings and period parquet, modern buildings, lofts and former workshops, complex urban logistics, building co-ownership authorisations and strict standards such as accessibility (PMR), fire safety and ERP regulations. The company states a vision of a world where beauty and innovation redefine every place, and frames its work around human experience as well as social and environmental challenges.

Isospace was founded in 1997 as a general contractor for the fitting-out of professional spaces. From its base in the Paris region — the company is headquartered in Boulogne-Billancourt in the Hauts-de-Seine department — it built its activity around a single integrated offer covering design, architecture and construction works, rather than separating project management from execution. Over the following decades the company extended its scope beyond offices into retail, hotels and restaurants, and added a dedicated brand-focused activity, Isospace Brands, covering visual merchandising, bespoke furniture, shop-window decoration, stands and point-of-sale advertising. This arm developed particular expertise in airport zones, where the company reports a strong reputation for professionalism and finish. By the 2020s Isospace reported having delivered more than 3,500 projects since its creation, working on surfaces from 150 m² to 10,000 m², from open-plan offices to corporate headquarters, and employing around 60 people. It operates a 600 m² workshop in Bry-sur-Marne where artisans produce bespoke joinery, lighting and glasswork, large-format printing, adhesive lettering and logotypes, and film decorations. The company presents its integrated, agile and human approach as a deliberate alternative to a fit-out market dominated by large players and standardised solutions. It argues that companies increasingly seek hybrid, flexible and embodied spaces that reflect their culture and real uses, and it emphasises bespoke, singular projects. As a general contractor it manages all trades and furniture while avoiding an external project management team, giving clients a single point of contact, a single quote and a single schedule, and it is able to carry out works in occupied premises so that clients can remain operational. Its Paris office fit-out specialism addresses the specific constraints of the capital: Haussmann-style buildings with mouldings and period parquet, modern buildings, lofts and former workshops, complex urban logistics with coordinated deliveries and restricted access, building co-ownership authorisations, and strict standards including accessibility (PMR), fire safety and ERP regulations. The company states a forward-looking vision of a world where beauty and innovation redefine every place, and frames its work around human experience as well as social and environmental challenges, citing CSR certification.
