Hôtel de Paris Monte-Carlo by Affine Design in Monte Carlo, Monaco
The Hôtel de Paris Monte-Carlo is a belle-époque palace hotel on the Place du Casino in Monte Carlo, Monaco, opened in 1864 beside the Casino de Monte-Carlo and still owned by the Société des Bains de Mer that built it. Between 2014 and 2018 it was reinvented, wing by wing and without ever closing, by the Paris studio Affine Design under its founder Richard Martinet, working with the Monegasque architect Gabriel Viora, with the restaurant Ômer by Pierre-Yves Rochon and Le Bar Américain by David Collins Studio. The original building was drawn by Godinot de la Bretonnerie, and its sculpted facades by Édouard-Jean Niermans date from 1909–1910. It joins the Hôtel de Crillon in Paris, on which Martinet also worked, and grand hotels such as Raffles Hotel Singapore and The Ned on Archtene.

François Blanc’s palace on the Place du Casino, 1864–1960
The hotel was the centrepiece of the resort that Prince Charles III and the entrepreneur François Blanc created in the 1860s. Blanc’s ambition, still quoted by the Société des Bains de Mer, was “a hotel that surpasses everything” created until then, and the Hôtel de Paris opened in 1864 on the square it shares with the Casino, before the Café de Paris, the Opéra de Monte-Carlo and the Hôtel Hermitage rose around it. Niermans gave it the exuberant facades of 1909–1910, with frescoes by the painter Paul Gervais; the building was raised again in 1920 by Émile Molinié, Charles Nicod and Albert Pouthier and once more around 1959–1960 under André Bruyère. Affine Design reads the house as the product of three great eras: Blanc’s founding hotel, the major extension of the early 1900s, and the 1960s under the auspices of Aristotle Onassis, when guests such as Winston Churchill added to its legend.

Affine Design’s transformation, 2014–2018
The Société des Bains de Mer began the transformation in 2014 and entrusted it to Richard Martinet and Gabriel Viora, describing a programme of partial deconstruction, reconstruction, harmonised volumes, new spaces and new suites, carried out on an occupied site while the hotel stayed open. Affine Design supervised the architecture and interior architecture from feasibility studies to completion. The walkways and circulation were redrawn so that guests move more easily through the house; the 1904 entrance hall was restored and given skylights; every facade was restored and the south front was rebuilt to respect the original structure; and the roofs were redesigned, one of the major interventions. At the core of the plan a Mediterranean patio of 671 square metres was opened up, planted with palms and lined with boutiques for Graff, Harry Winston, Omega and Stardust, with floor mosaics by Pierre Mesguich. Inside, Affine’s palette is golden hues fading into white, with black lines and shades of grey, a contemporary reading of the palace rather than a period reconstruction.

A step-by-step reopening
The work was revealed in stages. In May 2017 the rebuilt Rotunda wing opened with new rooms of at least 34 square metres, along with Le Grill on the eighth floor, whose sliding roof opens to the sky above the sea. The Princess Grace Suite was inaugurated in November 2017 by Prince Albert II and Princess Stéphanie; in June 2018 Le Bar Américain reopened with interiors by David Collins Studio and a new terrace over the sea and the Place du Casino; and in December 2018 the patio was unveiled and Le Louis XV – Alain Ducasse à l’Hôtel de Paris returned to its original rooms facing the square, where the gilding, frescoes and hangings of the Salle Empire were restored. Alain Ducasse’s Ômer, designed by Pierre-Yves Rochon, followed in 2019 on the ground floor of the Rotunda wing, and the rooftop Prince Rainier III Suite completed the hotel early that year, leaving 207 rooms, some 60 per cent of them suites. The whole programme has been reported at around €270 million.

The Princess Grace and Prince Rainier III Suites
The two royal suites at the top of the building are the most personal rooms in the hotel. Prince Albert II worked with Martinet and Viora on both, in tribute to his parents. The Princess Grace Suite, created from the former Winston Churchill Suite as a duplex over two floors, has a glass partition etched with the princess’s handwriting, a sand-coloured carpet printed with her footprints, terraces and an infinity pool facing the Mediterranean. The Prince Rainier III Suite, the largest in the hotel, has a pared-back palette of black and white marble, small figurative sculptures welded by Prince Rainier himself, its own infinity pool looking over the domes of the Casino, and an office where his portrait as a young man is framed by a hand-painted glass wall in gold and navy. In the bathrooms of the rooms and suites Affine used generous slabs of Arabescato marble, basins carved from blocks of marble 30 centimetres thick, straw marquetry and bespoke furniture.

The photographs open with the hotel’s domed corner and rotunda in afternoon sun, then step into the palm-planted patio and its colonnaded galleries, with their star-patterned mosaic floors, before returning to the main facade on the Place du Casino. Inside, they move from a suite salon to the sitting room, rooftop pool, office and a bedroom of the Prince Rainier III Suite, through light-filled suite salons and the living room, a bedroom and a restored door medallion of the Princess Grace Suite, and end in a guest bedroom with a folded white headboard wall and a marble bathroom opening onto a balcony.
