Normally, rooftops are empty spaces for every building but this will never be the case anymore if you do the same what the designers of the House in Leiria did with its rooftop.
If you have heard of the rooftop bathroom, this time it will be a rooftop greeneries and party place. With this idea, who would say that space for an open-air party is hard to find today? You can have a party anytime you wanted at your rooftop, make it as your garden area, play area and more. There are a lot of things we can doo with our rooftops. Take the House in Leiria as your inspiration and you will never be wasting your rooftop space again.
