Here's an exclusive look around one of London's most incredible mansions - complete with cinema, spa, gym, and nanny's quarters
Business Insider was given an exclusive tour around one man's £19 million Belgravia mansion in Chesham Place, a few days before he moves in.
This is all thanks to Mathilde Allibe, the CEO and founder of the elite architecture and interior design company Secretcape.
Secretcape decorates the interiors for £10 million to £300 million homes across the world. Currently she has seven projects on the go - six in London and one in Spain.
She has several teams that work for her all the way through design, architecture, project management, finances, and aftercare. The latter is a team that helps clients move in, once the project is completed. Her clients give her budgets of "millions, not one million" to design the inside of a house. Some give a limitless budget.
