The Shangri-La Hotel in the Shard, London, may be the tallest tower in the British capital city, but it offers more than just impressive views of London but also what other hotel guests are doing.

Considered a voyeur's or Peeping Tom's delight, this weak side of the high-end hotel that just opened last week is due to a quirk in the hotel's design that allows guests to see through the windows of other hotel guests.

It is due to the glass panels of the 310-metre skyscraper that protrudes from its corners and acts at the same time as mirrors when room occupants switch on the lights at night.

Darren Gearing, hotel general manager, admitted to the Financial Times the newly discovered flaw, but added blinds could be installed if guests seek privacy.

Reports of the unexpected views led to some wisecracks shared over social media sites. Hippie94 tweeted, "I wonder if the rooms could see each other? If you're in room 152 and can see 154, can 154 see into 152? That would be a moneymaker for exhibitionism."

Decgeek opined that the architect is probably miffed at the thought that blinds would be installed in the glass tower which he believes "calls attention to the isolation of man."

MistaButters' naughty tweet was: "If I have a high room floor with a great view, there is no way I'm closing the blinds, even if I'm in my birthday suite. Actually, especially if I'm in my birthday suit."

In turn, Suboptimus Prime's suggestion was to change the name of the building to The Shared Hotel.

Italian architect Renzo Piano designed this landmark near the London Bridge. It is also called Europe's first vertical city because of the 40-mile views it offers and is visible to drivers on the M25.

Many of the apartments, priced between £30 million and £50 million, remain unsold. It is the third Shangri-La hotel in Europe after the first opened in Paris in 2010 and the second in Istanbul in 2013.
