LONDON—Dorchester Collection is investing in current and upcoming renovations to several of its properties.

The Beverly Hills Hotel is marking its 100th anniversary with enhancements to the property. Tihany Design will oversee the renovation. The lobby, Polo Lounge, pool cabanas, Cabana Cafe, guestrooms and suites will all be restored.

The Dorchester in London will debut 22 suites designed by Alexandra Champalimaud this summer. Champalimaud's design was inspired by classic but modern British residential style. The hotel offers marble foyers, hardwood floors, marble fireplaces and window treatments. The bathrooms will feature separate showers with large drench showerheads in addition to bathtubs. Guestrooms will offer remote touch control lighting, air-conditioning and mood lighting.

The guestrooms, including the Presidential Suites and Salvador Dali apartment, of the Le Meurice in Paris have been refurbished by Charles Jouffre. The Valmont Spa is also being renovated by Jouffre and De Ambroggio & Lafanechere. The new Yquem dining room will open this fall in the hotel's destination restaurant.

The Hôtel Plaza Athénée in Paris has debuted its newly renovated Royal Suite. Marie José Pommerau designed the suite with a contemporary style. Apricot, raspberry, violet, beige and mauve make up the room’s color palette.

The Le Richemond in Geneva will be refurbished in the second half of the year. Its public areas, suites, restaurant and bar will be redone.
