Just the weight of Gingerbread used in the construction of the house on their facebook page.
like Christmas The Langham’s Gingerbread House comes once a year. Last year’s sweet treat was London’s biggest ever Gingerbread House and this year to grab the headlines the hotel are offering a free festive afternoon tea to anyone who guessThe Gingerbread house is a humongous 4.5ft high and stands at the entrance to Palm Court, one of the capitals most popular afternoon tea spots. If you fancy a glance pop down to the hotel this month and whilst you’re there we suggest you try the festive afternoon tea. It sounds dish delish!
