Redesigned by local firm Gabellini Sheppard, the 15-story Knickerbocker Hotel now features casually elegant public areas and 330 unique guestrooms. “Our design aesthetic is a reflection of the original legacy of the hotel but tailored to the next generation of guests,” says firm partner Kimberly Sheppard.

In the Knickerbocker’s neutral-hued ground floor, bands of light- and medium-toned marble stretch underneath a double-tiered, semi-domed ceiling.

Following its spring opening, the Baccarat Hotel & Residences New York unveiled the world’s first Spa de La Mer in partnership with the skincare brand. As with its overall design for the property, Paris-based design firm Gilles & Boissier focused on creating strong visual links to Baccarat crystal throughout the subterranean spa.

According to Gilles & Boissier principal Dorothée Boissier, the spa’s common areas are “very white, silver, and bright” and include a 55-foot-long pool with black and white tile floors.

Designed by New York-based AvroKO, 1 Hotel Central Park is a recently opened eco-luxe offering from Barry Sternlicht that features natural materials—such as 16,000 fallen twigs inlaid on large steel front doors—in reference to its nearby namesake.

In keeping with the 1 Hotel brand’s environmentally sensitive ethos (the hotel is going for LEED certification), the designers worked to blur indoor-outdoor lines in the 229 rooms and suites through the use of built-in window seats and paned-glass showers, inspired by a greenhouse.

Under Choice Hotels’ Ascend Collection, the 122-room Paul was designed in part by New York’s Silvia Zofio of SZ Projects. Its lobby sits beneath a perforated metal ceiling that complements patterned marble floors and concrete walls.

Ronica Sharma of Sharma Group Development went with whitewashed surfaces and pops of color, like navy and cherry red, in the hotel’s more casual guestrooms.

Martin Brudnizki, founder of London- and New York-based Martin Brudnizki Design Studio, repurposed a 19th-century office building as Commune Hotels + Resorts’ Beekman Hotel—set to open early next year.

The Beekman’s interiors were stripped to their purest forms, “focusing solely on using the highest quality finishes, richest materials, and carefully curated furnishings to ensure a lovingly worn and authentic aesthetic,” says Brudnizki.

Also slated for 2016, tommie Hudson Square will be a micro-room hotel from Commune Hotels + Resorts that hopes to attract Millennial guests with 1970s-inspired, AvroKO-designed spaces that emphasize efficiency.

Guests will enter the hotel’s 325 rooms through the bathroom, so it was necessary to “soften the distinction between the bathing area and the bedroom with finishes that felt more loft-like and residential,” says AvroKO partner Adam Farmerie.

A joint effort between Starwood Hotels & Resorts’ in-house team and New York-based Glen & Company, the 128-room Aloft Manhattan Downtown — Financial District will open this fall.

Aloft rooms will feature modular furniture, softgoods in vivid colors, and industrial touches. “We strived to take the standard brand elements and make them a little more sophisticated for the urban market,” says Glen & Company founder Glen Coben.

Even, InterContinental Hotels Group’s new wellness-centered brand, enters New York later this year with the 150-room Times Square South location, designed by Glen & Company. “The aesthetic ties into nature and natural materials to create almost an urban oasis,” company founder Glen Coben points out.

Once a housing and studio space for creatives and intellectuals, the 173-room Renwick was reimagined as a contemporary hotel by local firm Stonehill & Taylor. Each guestroom was designed as its own artist’s studio with “blank canvas” white walls broken up by a bold band that rises through the headboard and onto the ceiling.

The Stonehill & Taylor team embraced the 1928 building’s artistic history by nodding to the processes of drafting and sketching. “Linework and imperfect or unfinished art is featured throughout,” says principal Michael Suomi.

The former 60 Thompson was rebranded as SIXTY SoHo, part of hotelier Jason Pomeranc’s SIXTY Hotels, following a multimillion-dollar redesign by Martin Brudnizki Design Studio. Its revamped Sessanta restaurant now features black leather booths and bentwood chairs inspired by midcentury Italy.

New York designer Joe Ginsberg referenced the look and feel of a high-end Manhattan apartment for Marmara Park Avenue, a modern 128-room hotel that was converted from a 1927 office tower. Guestrooms offer wood floors, abstract art, and multi-colored accent pillows and sofas.

Originally opened in 1903, the 132-key Gregory hotel stands out following a $10 million renovation by Bill Rooney Studio that transformed interiors with an Old World New York aesthetic. A bright contrast of black, white, and gray highlights original architectural elements in the guestrooms.

For the Ludlow—which opened last year—hotelier and designer Sean MacPherson dreamed up a 1,500-square-foot, two bathroom penthouse, which features floor-to-ceiling casement windows, handmade silk rugs atop hardwood floors, Moroccan-made pendant lights, and rock music-inspired décor.

A $20 million renovation by locally based Rockwell Group gave guestrooms at the 193-key Time hotel an updated midcentury vibe that includes a chalky gray pinstripe wallcovering, freestanding natural wood furniture, custom rugs in blush and purple hues, and glass box wardrobes and minibars in wooden cases.

The 42 retooled one- and two-bedroom suites at the Mandarin Oriental, New York are the handiwork of HOK. A juxtaposition of Manhattan and Asian-inspired motifs, art-filled accommodations include the amethyst-tinged Central Park West suite, which pops with modernist details and graceful residential touches, such as a bold circular sofa.

Designer Marcela Caycedo, president of Espacios Design Studio in Long Island City, took inspiration from the 34-room Brooklyn A Hotel’s previous life as a circa-1910 industrial building. Existing wood columns and beams and brick walls were left exposed, while wallcoverings feature historical facts and pictures of local neighborhoods.

Boro—a 108-key, design-centric boutique hotel in Long Island City—was crafted by New York’s Grzywinski + Pons with light, soaring ceilings, industrial touches, and minimalist guestrooms, where leather, sisal, and cork elements abound.

Local firm Josh Held Design conceived GuestHouse, a 2,500-square-foot duplex penthouse suite, for Dream Downtown. The bi-level space’s $1 million, celeb-inspired makeover includes an elaborately sculpted plaster ceiling in the living room with lights that changes color.

Previously the Gershwin Hotel, Evelyn is a 160-room property from Triumph Hotels with interiors by New York’s Silvia Zofio of SZ Projects. The $30 million redo created residentially inspired guestrooms with Art Nouveau-era design aspects that include walnut furniture, brass fixtures, and a warm cream color palette with blue accents.

The Spanish brand’s North American flagship, Room Mate Grace is a recent Midtown renovation from Madrid-based Lorenzo Castillo, who enveloped the 139-key hotel’s guestrooms in boldly floral, vaguely Oriental gold, bronze, and indigo tones. The designer says he “wanted to create a hotel with a sophisticated ambiance using lacquer, handmade wallpapers, velvet fabrics, and other textures.”

Set within Midtown Manhattan’s upcoming Hudson Yards—the largest private real estate development in U.S. history—the 200-room, Yabu Pushelberg-designed Equinox Hotel will be the health club brand’s first. Its design will emphasize movement, nutrition, and regeneration throughout multiple terraces, restaurants, and lounges. Shops and retails offerings, like Neiman Marcus, will be nearby.
