Ultra Modern Home Escape

You were not rich until you came across this lucky stone that you found in the river. Ever since you found the stone your luck has changed amazingly. You got a job, you soon got a promotion and now you have been shifted to an ultra modern home where you will be living. You go to the new house that you have been given by the company that you work for and after spending a night in the lavish house you get up in the morning and decide to go out for a walk. Strangely you are unable to find a way to get out from the house. You have to find it though.
