Hôtel de Chambon

95 rue du Cherche-Midi, Paris 6th
Trophy Delivery Q1 2026

A private mansion of the Faubourg Saint-Germain, the Hôtel de Chambon occupies a rare plot between courtyard and garden, a step away from boulevard Raspail. The acquisition was sourced off-market, negotiated over an extended period without a competitive process, with a debt structure calibrated on the construction timetable.

The group is carrying out a full heritage restoration: façades and original joinery, reorganisation of interior volumes, creation of reception spaces on the garden level and restoration of the walled garden. The project is delivered alongside heritage architects and contractors specialised in Parisian period buildings.

The asset has been covered by the specialist real estate investment press. Delivery is scheduled for the first quarter of 2026 and the asset is intended to be held long term.

Domaine du Château

20 / 20B boulevard du Château, Neuilly-sur-Seine
Trophy Development 15 residences Q1 2026

Located on one of the most sought-after axes of Neuilly-sur-Seine, the Domaine du Château brings together a built ensemble and its park on a land footprint that is uncommon west of Paris. The transaction was originated directly with the owner, then structured in two stages in order to separate the holding phase from the development phase.

The programme provides for fifteen residences, organised around the preservation of the main building and a measured intervention on the park. The design favours large dual-aspect floor plates, careful execution standards and a deliberately contained density.

The ensemble is held by the fund and monitored in-house across financial, technical and commercial workstreams. The first delivery phase is expected in the first quarter of 2026.

Hôtel particulier Pierre 1er

17 avenue Pierre 1er de Serbie, Paris 16th
Held 1,074 sq m Opening 2026

This 1,074 sq m private mansion occupies a corner position on avenue Pierre 1er de Serbie, at the heart of the Parisian golden triangle. The building also houses the group's Paris office, allowing day-to-day supervision of the works and of neighbouring relations.

The project consists of a full upgrade of the building, with the original layout restored on the principal floors and reception and working spaces created at street level. The structure combines equity with amortising senior debt.

Opening is scheduled for 2026. The asset is held long term and intended for mixed use, combining representative offices and private space.

Résidence Marceau

61 avenue Marceau, Paris 16th
Held 620 sq m · 4 units Q1 2026

The transaction covers four units totalling 620 sq m within a Haussmann building on avenue Marceau, between the Étoile and the pont de l'Alma. The acquisition was carried out unit by unit, as part of a patient accumulation strategy within a single condominium.

The team is undertaking a complete refurbishment of the units, restoring parquet floors, mouldings and fireplaces, rebuilding the wet areas and upgrading technical installations. The exit strategy relies on the depth of the prime residential market in the 16th arrondissement.

Marketing, launched at price levels above €11,600 per sq m, has been reported in the specialist press. Completion is scheduled for the first quarter of 2026.

Résidence Prony

95 rue de Prony, Paris 17th
Held 149 sq m Haussmann 2025

Close to the parc Monceau, this 149 sq m Haussmann apartment illustrates the residential format the fund pursues alongside larger assets: a contained ticket, rapid execution and a clear margin of safety at entry.

Works consisted of a full refurbishment completed in 2025, with partial redistribution of volumes, preservation of original decorative features and a complete upgrade of building services. Funding combined equity with conventional bank debt.

The asset is held and let. It contributes to the recurring income base of the proprietary portfolio.

Résidence Marignan

rue de Marignan, Paris 8th
Exited Q4 2025 149 sq m + 46 sq m terrace

A few metres from avenue Montaigne, this 149 sq m apartment with a 46 sq m terrace combined a rare location with outdoor space that is unusual for the district. The acquisition was completed off-market, from a private vendor.

The group carried out a full refurbishment and repositioned the asset towards international buyers seeking floor area with outdoor space in the golden triangle.

The exit was completed in the fourth quarter of 2025, within a marketing period consistent with the original business plan.

206 Saint-Germain

206 boulevard Saint-Germain, Paris 7th
Exited Q4 2025 18th-century building

An eighteenth-century building on the most established stretch of boulevard Saint-Germain, this asset was acquired in a complex legal configuration that narrowed the field of potential buyers.

Work focused first on clarifying the tenancy situation and the ownership structure, then on a works programme targeted at the common areas and the vacated units.

The disposal was completed in the fourth quarter of 2025, once liquidity conditions had been restored. The transaction illustrates a value-creation thesis based on structuring rather than on market movement alone.
