This concept hotel suite inside a plane cabin comes with a king-size bed, drawers, and a mini sofa

The London-based design and innovation firm Seymourpowell has unveiled plans for a luxury plane cabin suite that would offer first class passengers private rooms with lie-flat seats that turn into beds.

First Spaces - which we first read about on The Telegraph - has been designed to evoke "a contemporary boutique hotel" in the sky, according to a press release from the company.

Intended for Airbus A380 aircraft, the first-class section is made up of four single rooms and two double rooms. Each room comes with a bed, TV screen, a table, storage space, and a tablet to control the room's functions. 

Seymourpowell was inspired to design the suite after speaking to passengers who said that above all they want privacy during a flight, the company's cofounder Dick Powell told Business Insider over the phone.

Though it's unclear if First Spaces will become a reality or how much a room would cost, Powell said the company is currently "having interesting discussions" with a number of aircraft suppliers. "It's at least three years away from being in the air," he said.

The concept has also been nominated for a Crystal Cabin Award at the Aircraft Interiors Expo in Hamburg on April 5-7, where it's likely to make an impression.
