luxury listed apartment / penthouse for sale Yvelines, France

Rare are the properties that transcend their era to become immutable works. This 5-room Triplex of the Phélypeaux Wing is one of them. Nestled in the West wing of Château de Pontchartrain — a listed monument, residence of ministers of Louis XIV and Louis XV — this 111.68 m² habitable residence, spread over three levels, offers an exceptional living environment unmatched on the Île-de-France market. On the ground floor, a spacious bright living-dining room opens onto a private terrace of 30.26 m², facing WEST over the gardens of the estate — the same gardens designed by André Le Nôtre for Chancellor Louis XIV. Upstairs, three or four spacious bedrooms, a bathroom and a shower room, generous storage spaces, a fully equipped kitchen with premium finishes. Floating parquet, cleaned cut-stone cladding, restored wooden joineries — the art of the period reinterpreted with contemporary comfort standards. The location is a decisive advantage: 25 minutes from Paris via the N12 and 33 minutes from Paris-Montparnasse (Line N of the Transilien), Jouars-Pontchartrain concentrates all the qualities of an exceptional Île-de-France way of life in a preserved environment of 5,800 inhabitants. 18 minutes away, the Saint-Quentin-en-Yvelines basin brings together Airbus, Renault, Thales, and 35 international groups. 30 minutes away, the Paris-Saclay campus hosts HEC Paris, Polytechnique, and CentraleSupélec. On the fiscal front, this triplex represents an exceptional patrimonial optimization. The €634,500 renovation budget is fully deductible from the total income under the Historic Monument scheme — without cap. Estimated savings effort of €3,935/month, market rent at €1,145/month. Lot F03 is currently the only available apartment in this exceptional program — delivery set for November 1, 2026. A unique opportunity, without competition on the Île-de-France patrimonial market.
