A Special Architecture Assessment reconstructs the verified inventory of Jacques Couëlle's Riviera houses and the Antti Lovag school beside them: twelve works graded on state heritage evidence, the misattributions that move prices, and the deed-register market around the works.

1 · Purpose and method

Architectural provenance is an asset class on this coast, and none is more traded on — or more loosely claimed — than the name Jacques Couëlle. This note reconstructs the publicly verifiable inventory of Couëlle's Riviera houses, and of the school beside him: Antti Lovag, the self-described habitologue who worked in Couëlle's office before his own bubble houses made Théoule famous. Every work below is evidence-graded: A for state heritage records and institutional archives, B for established architectural databases and reputable press, C for commercial attributions not yet matched to an archive file. The official Couëlle fonds records eight châteaux, 260 gardens and more than 100 villas in France and the Mediterranean — a body of work that remains substantially uncatalogued. That gap is precisely where money changes hands on attribution alone.

2 · The architect and the school

Couëlle's Riviera trajectory runs in three acts. The young architect of the 1920s rebuilt bastides from historic fragments — the Bastide Saint-François at Grasse, the Château de Castellaras for the Schley family — Provençal in appearance, modern in use. The post-war Couëlle became a maker of villages: some ninety neo-Provençal houses at Castellaras-le-Vieux, commissioned by the Seligman bank around his own 1926 château. And from 1962 the sculptor emerged: the five prototype sculpture-houses of Castellaras-le-Neuf — of a planned fifty — and the marine village of Port La Galère. In that office worked Antti Lovag, who contributed shell models and the interior of villa no. 5 before striking out alone: the Domaine Gaudet at Tourrettes-sur-Loup, then Maison Bernard and the Palais Bulles at Théoule, both now protected and the second world-famous. Léopold Vittorge carried Port La Galère's later phases. Three hands, one lineage — and three price histories that must not be confused. On the maps in this note, every Couëlle or Lovag residential work is marked by a diamond.

3 · The verified inventory

Twelve works survive public verification, mapped above and graded below. Note what the grades do: nine works carry A or B evidence — state heritage labels, archive records, academic study. Three of the most commercially interesting — Villa Oxygène in Super-Cannes, the large 1973 villa at Théoule, the Maison de l'Escaillon in the Estérel — rest on grade-C attributions: plausible, repeatedly published, and still unmatched to an original project file in the Couëlle fonds at Roubaix. A C-grade is not a defect; it is a due-diligence instruction.

4 · The Théoule cluster

One commune holds four of the twelve works, within a kilometre of water. Port La Galère is Couëlle's marine village — his sculptural first group, Lovag on site, Vittorge completing some 400 apartments through 1979; the ensemble carries the state's Architecture contemporaine remarquable label. Above the same cove, Lovag built his first complete bubble residence, Maison Bernard (1971, now an endowment-fund cultural site), and then the Palais Bulles — some 1,200 m² of interconnected spheres, acquired by Pierre Cardin in 1992 and the most photographed private silhouette on the Corniche de l'Estérel. A fourth work is quieter: a Couëlle-attributed villa of 1973 — thirteen bedrooms on 2.4 hectares — currently offered through our agency; its point on the map above is deliberately indicative.

5 · Attribution — where prices are made and lost

The market repeatedly pays Couëlle prices for non-Couëlle houses and misses Couëlle houses trading unattributed. The corrections below are drawn from the Ministry of Culture's own research and the archive record; they are the ones a buyer's file must get right, because a signature supported by an archive file and a signature supported by a brochure are different assets.

6 · The works in the deed register

We matched each work against the state's deed register, address by address, across villas and apartments alike. The pattern is the finding: of twelve works, only the two Couëlle ensembles actually trade. Castellaras and Port La Galère are liquid markets inside signed architecture — 43 house deeds and 285 apartment deeds respectively. Every single-signature house is structurally off-market: protected, endowment-held, or simply never sold since records began. One caution the register itself supplied: the €30.5M deed of 2020 on Villa Oxygène's avenue belongs to a different, far larger property — precisely the kind of neighbouring-deed halo a brochure borrows and a buyer's file must strip out.

7 · The market around the works

The deed register prices the territory the works sit in. Across the seven host communes, the state's DVF register records — at €3M and above — the market below. Castellaras itself is the sharpest signal: the lanes carrying the name have recorded 43 house sales of €1M or more for a combined €126 million, topped by €14.75M in June 2025 and €13.1M in December 2025 — a Couëlle-planned village outperforming its own commune's median by a wide margin. In Valbonne, where Couëlle's Domaine de Beaumont was offered around €31.5M in 2023, the largest priced sale of the DVF decade — €7.1M, 2024 — was closed by Elena Agueeva Real Estate.

8 · A collector's assessment

Scarcity here is structural, not rhetorical. Couëlle completed five of the fifty sculpture-houses planned at Castellaras-le-Neuf; Lovag's independent residential works number three on this coast, two of them protected and effectively permanently off-market. What remains tradable is a single-digit universe, and grade-C attributions are where both risk and opportunity concentrate: an archive match at Roubaix can turn a well-documented villa into a catalogued Couëlle — and its absence can quietly do the reverse. The discipline runs through our own own register: one Théoule work is offered as a Couëlle signature property; a Mougins villa is described only as built in the spirit of Couëlle — homage and authorship never share a sentence. The sober conclusion: buy the file, not the brochure. We verify attribution evidence, heritage-label status and the deed history before any Couëlle or Lovag name enters a transaction file.

Method. Inventory reconstructed from public sources 22 July 2026: Ministry of Culture heritage records (labels ACR, Mérimée/POP), the Jacques Couëlle fonds description (Archives nationales du monde du travail, Roubaix), academic and architectural references. Evidence grades A/B/C as defined in section 1; grade-C works are provisional attributions, not authenticated Couëlle works. Market figures: DVF (DGFiP), €3M+ unless stated; per-work register traces are street-matched across the villa and apartment deed registers at all values — absence of a deed reads as no recorded transfer since 2014, not as proof no private transfer occurred. This note is analysis, not architectural-historical certification. Prepared by Elena Agueeva Real Estate — elena@elenaagueeva.com · +33 7 66 44 02 34.
