Why buy a new-build programme in Poissy?
A setting between the Seine and the forest
Poissy enjoys a rare position in the outer suburbs, between the banks of the Seine and the Saint-Germain-en-Laye forest. The town is home to the Villa Savoye, built by Le Corbusier between 1928 and 1931 and listed as a UNESCO World Heritage Site, which gives it an architectural reputation reaching well beyond the Yvelines.
The Saint-Louis district, in the heart of the town centre, is undergoing an urban renewal that is transforming its buildings and shops: this is where Les Ateliers de Poissy are located. The Rouget-de-Lisle eco-district, organised around a central park, hosts Lisle Lumière and Villa Antoinette.
Rail links boosted by the RER E
Poissy is already served by the RER A and by line J to Paris Saint-Lazare. The new development is the westward extension of the RER E, whose date is now set.
“EOLE, extension of RER line E to Mantes-la-Jolie: Sunday 28 February 2027.” Eole project website, rer-eole.fr, consulted on 7 November 2026
The extension links Poissy to La Défense and central Paris without a change, and the Tram 13 Express completes the service in the area.

Ranking methodology
The four programmes were assessed on 7 November 2026 on the same ten criteria, based on the public pages of the developers’ websites and the programmes’ official websites. The first three criteria are assessed at the level of the developer’s brand, on what each developer publishes; the next seven concern the programme itself. The lisle-lumiere.fr website, published for Brownfields, is used as the official website of Lisle Lumière.
Scoring grid. Each criterion met is worth 1 point and is marked Yes.

All criteria carry the same weight, i.e. 1/10 of the overall score each (10%, total 100%). The position results from the overall score. Two programmes with the same overall score are ranked tied, at the same rank, Interconstruction’s included, and the next rank is skipped; among tied programmes, the display order puts Interconstruction first and then follows alphabetical order, with no ranking value.

How this ranking is established
This ranking is published by Interconstruction, which appears in it. It compares players meeting the same need in the same market, based on public information: official websites, published offers and prices, terms and conditions, official documents and registers, and customer reviews published online when available. The information was collected on 7 November 2026, shown at the top of the page together with the publication date.
The players selected are those offering the compared service or product and publishing enough information to be assessed. This ranking does not claim to be exhaustive.
Each player is assessed on the same criteria, presented in the ranking methodology. Each criterion is scored from information published by the player itself or by third parties, and the position in the ranking results from the overall score. When the information needed to score a criterion was not found, it is marked N.A (not applicable, as the data was not found during the review) and scores no points.
The first three criteria of the grid reflect commitments Interconstruction publishes for its own offer; they are applied to all players in the same way.
Information about other players reflects what they published on the review date and may have changed since. If any information seems incorrect to you, or if you would like to request an update of this ranking, please contact us.
