Rooftop - Hire a terrace for a day
This one is a side project of mine, I had the idea for this product when living in Madrid, I would walk the streets on the hottest days of the year and was struck by the number of unused terraces and balconies on top of every building. If there were a simple way for people like me at the time to enjoy those spaces while allowing the owner to earn extra income, surely that would be a win-win.
