What SOCIETE ANONYME D'ECONOMIE MIXTE IN SITU does

SEM IN Situ (SOCIETE ANONYME D'ECONOMIE MIXTE IN SITU) is a mixed-economy public company (Société d'Économie Mixte) controlled by Valence Romans Agglo, operating in Alixan, France. Created in 1970 and restructured in 2021 around an economic-and-commercial real estate mandate, the company manages and develops a portfolio of three car parks (570 spaces total at P4 Vercors, P5 Drôme, P6 Brillat-Savarin near Valence TGV station) and five economic buildings (M3 Rovaltain, Technosite, Building R, Building Orion, Building Condorcet) distributed across the Valence Romans Agglo territory of 54 municipalities and ~227,000 inhabitants.

Revenue is generated through three streams: (i) recurring rental income from professional and activity spaces (incubator offices of 10–20 m² at Technosite, activity modules up to 260 m² in relay buildings, plus ~1,000 m² of commercial ground-floor space at M3); (ii) parking operations, combining hourly and weekend pay-as-you-go tariffs, OnePark-distributed online reservations, annual corporate subscriptions tiered by office area (€500–€800 HT/year) restricted to Rovaltain-zone companies, and a €51/month EV-charging subscription operated via partner E55C; and (iii) co-investment and development fees on urban revitalization projects, notably a ~10,000 m² redevelopment with Rampa Développement at the Jean Bouin site in central Valence. Go-to-market is direct/sales-led through the company website (sem-insitu.fr) and [email protected], supplemented by the OnePark marketplace and the marchés-publics.info public-procurement portal.

The company is supported by an institutional ecosystem including Valence Romans Agglo (primary shareholder), Banque des Territoires (financing), SCET (engineering advisory from the Caisse des Dépôts group), Club Rovaltain (local business association), and Fédération des EPL. Stated investment capacity exceeds €30 million; share capital is €471,100 and headcount is 1–10 employees. Planned 2026 milestones include the P4 Vercors expansion from 430 to 690 spaces with photovoltaic canopies (€1.5M HT) and delivery of the Jean Bouin project in Q2 2026.

Scale indicators5 records

Recent moves9 records

Expansion highlights4 records

Broad incumbents

• Bouygues Immobilier: Bouygues Immobilier is a major French residential and commercial real estate developer. Its activity in economic and tertiary real estate development overlaps with IN SITU's economic real estate mandate, though Bouygues operates as a private developer at national scale.
• Icade: Icade is a major French real estate company (CDC subsidiary) with offices, healthcare, and residential portfolios. IN SITU's Caisse des Dépôts ecosystem alignment and its portfolio of office, activity, and tertiary assets make Icade a broad incumbent comparable at the portfolio level, though at much larger scale.
• Q-Park: Q-Park is one of Europe's largest parking operators, present in France and multiple European countries. IN SITU's parking operations (3 facilities, 570 spaces with EV charging) are functionally similar to Q-Park's transit-adjacent parking products, but at much smaller scale and with a public-mandate model.
• Frey: Frey is a French commercial real estate developer focused on retail parks, urban retail, and tertiary assets. While Frey operates at larger scale nationally, its focus on commercial and economic real estate development overlaps directly with IN SITU's commercial property and activity unit portfolio.

Direct peers

• Nhood: Nhood (formerly Auchan Immobilier) is a French real estate operator focused on retail and commercial ground floor revitalization, mixed-use regeneration, and sustainable urban development. IN SITU's commercial ground floor revitalization mission and town centre activation programs in Valence mirror Nhood's core playbook.
• Indigo: Indigo is the largest parking operator in France, managing public and private parking facilities across the country. IN SITU's Rovaltain parking business (570 spaces) directly competes for transit-oriented parking demand near TGV stations, making Indigo a direct peer for the parking revenue stream.
• Compagnie de Phalsbourg: Compagnie de Phalsbourg is a French real estate developer specializing in urban redevelopment, mixed-use regeneration, and town centre revitalization projects. IN SITU's Jean Bouin redevelopment and town centre commercial activation programs are highly comparable in approach and asset class.
• EFFIA: EFFIA is a major French parking operator and a subsidiary of Keolis (SNCF group). EFFIA operates station-adjacent parking similar to IN SITU's Rovaltain facilities and is a direct competitor for TGV-related parking demand and corporate subscription programs on transit corridors.

Emerging players

• Linkcity: Linkcity is Bouygues Construction's urban development arm, focused on mixed-use regeneration, sustainable districts, and public-private partnerships. IN SITU's Jean Bouin co-investment model and urban redevelopment studies align closely with Linkcity's PPP-driven approach.

Regional players

• Eiffage Aménagement: Eiffage Aménagement is the urban development subsidiary of Eiffage Group, active in eco-districts, urban renewal, and public-private partnerships across France. Its focus on territorial development with public partners and its mixed commercial-tertiary development activity mirror IN SITU's SEM-driven economic real estate model.
