Integrating a work of art into a building: what does that entail?

What a work costs, what it prohibits, and what it demands of the building

A painting hung after delivery is considered furniture. A work conceived with the project in mind is something else entirely: it becomes part of the program, it consumes a budget line, it constrains the technical design, and it legally survives the handover. Three sets of rules then overlap, and none of them addresses decoration. The first compels the public project owner to commission the work. The second protects the artist from the project owner themselves. The third governs the tax deduction for the purchasing company.

The 1% for art is a mandatory commission, not a decorative option.

Decree No. 2002-677 of April 29, 2002, as amended, mandates that 1% of the estimated cost of the works be allocated to the creation or acquisition of one or more works of art. The procurement procedures are set out in Articles L. 2172-2 and R. 2172-7 to R. 2172-19 of the Public Procurement Code, applicable since April 1, ²⁰¹⁹.

Three points govern the application. The basis for assessment is the estimated cost of the works , excluding taxes, as determined at the preliminary study stage, excluding roads and utilities and equipment expenses. The amount is capped at €2 million . The scope covers new constructions, extensions, and renovations involving a change of purpose, destination, or use : routine maintenance does not trigger any assessment.

The procedure then follows the budget. Below €30,000 excluding VAT for the purchase of an existing artwork, the awarding process is streamlined, following consultation with the Regional Directorate of Cultural Affairs. Above this amount, the standard public procurement regulations apply. In all cases, an artistic committee meets. A project manager who discovers this requirement during the planning phase has already lost most of their profit margin: the budget is fixed with the estimated cost of the work.

The artist's moral rights survive the reception of the work.

Article L. 121-1 of the French Intellectual Property Code grants the author the right to respect for their name, their status, and their work. This right is personal to the author and is perpetual, inalienable, and imprescriptible . It is not transferred with the physical object: the owner of the medium does not acquire the right to alter it.

Case law, however, has refused to establish this as a right of veto. The principle adopted, as reiterated by the National Council of the Order of Architects, is that the utilitarian purpose of a building precludes imposing absolute immutability . A modification remains lawful if it is strictly necessary and justified by aesthetic, technical, or public safety imperatives, or by adaptation to a new use. The assessment remains case-by-case.

The consequence is practical. In a renovation project, a fresco, a stained-glass window, a sealed sculpture, or a floor treatment designed by an artist cannot be treated like a surface covering. Relocating a monument illustrates the level of preparation such an intervention requires. The question arises before the planning stages, not at the time of removal.

What an acquisition opens up for a company

Article 238 bis AB of the French General Tax Code authorizes companies to deduct the purchase price of original works by living artists from their taxable income. The deduction is made outside of the accounting records, in equal installments over five years : the year of acquisition and the following four years, without proration in the case of purchases made during the fiscal year. An equivalent amount must be recorded in a special reserve account on the liabilities side of the balance sheet.

The cap is set at the higher of two amounts: €20,000 or 0.5% of turnover , less any donations made for sponsorship. Any unused portion is lost and cannot be carried over. The scheme was extended until December 31, 2028, by Article 89 of the 2026 Finance Law.

The most crucial requirement is not fiscal, but architectural. The artwork must be displayed to the public or employees for five years , in a location not reserved for a single individual or a select group. A painting in the CEO's office does not meet this requirement; a lobby, corridor, cafeteria, or accessible meeting space does. The program must therefore specify the exhibition space, its visibility, and information for the public regarding access.

The constraints that the work imposes on the building

The preventive conservation handbook of the French Museums' Research and Restoration Center provides guidelines. In the exhibition hall, the temperature is maintained between 18 and 22°C , with seasonal variations and no more than 2°C over 24 hours . For most objects, the relative humidity is between 40 and 65% , with daily variations of less than 5%.

Stability is what matters, more than absolute values. Fluctuating regulation is more likely to cause deterioration than a constant climate slightly outside the normal range, which shifts the focus to the sizing and operation of heating and ventilation systems . Regarding lighting, the guide recommends 50 lux for drawings and considers the cumulative dose, expressed in lux-hours per year—150,000 lux-hours annually for ivory, for example. A sensitive artwork placed facing a window or under natural zenithal lighting requires shading, ultraviolet filtering, and careful monitoring.

Why is arbitration taking place during the design phase?

Each of these three constraints shares the same characteristic: it costs little if addressed early, and is expensive if addressed late. The 1% levy is calculated based on a work estimate that is finalized in the initial stages. Hanging provisions, the load-bearing capacity of a wall, the routing of utilities, and the positioning of light fixtures fall under the structural work and electrical work packages, not the final fit-out. Consulting an artist after the building permit application has been submitted leaves only the bare wall and the movable picture rail.

The integration of interior design and visual art is still often treated as an afterthought in many projects. It would benefit from being considered as a fundamental technical requirement, on par with acoustics or summer comfort, which sustainable architecture practices have shown are often overlooked when relegated to the end of the project. An integrated artwork entails a budget, perpetual copyright, and a measurable environmental impact: three reasons to include it in the program.
