The New York Helmsley Hotel is set to undergo a $65m renovation, Starwood Hotels & Resorts Worldwide and Host Hotels & Resorts have announced.

Following the extensive re-branding initiative, the 774-room hotel in New York, US, will fly the Westin flag.

The hotel will debut in 2012 as Westin New York and will be the second Westin Hotel in New York City, accompanying the Westin Times Square.

According to Starwood, more than 15,000ft² of meeting space will be renovated and the hotel’s 300ft² guestrooms will be redesigned.

The lobby bar / restaurant has been planned for an extension to 42nd street and the entire façade of the building will be completely transformed.

Starwood said the renovation is estimated to last the six months between January and June 2012.

All the guestrooms, including 11 one-bedroom suites and one three-bedroom presidential suite, at the New York Helmsley Hotel will undergo a floor-to-ceiling renovation, the group said.

Eco-friendly materials to be used during the renovation include energy-conserving LED and CFL lights, water-conserving low flow plumbing and recyclable carpet pads, low VOC finishes for casegoods and GreenGuard-certified solar shades.

The hotel will have an addition of five new break-out rooms; the largest space will be able to accommodate 450 guests.

Westin, which is owned by Starwood Hotels & Resorts Worldwide, has more than 180 hotels and resorts in over 36 countries and territories.
