Dream Of Living In A Colorful 15 Storey Building With A Relax Garden On The Rooftop

I am living in a 15 storey building. There is a huge party going on the first floor. It was just recently constructed. On the top floor of that building was a seating space filled with cushion toys on the outdoor. The theme of that space was relax garden. That building had a lot of steps but no elevator. So people who couldn't climb, like old people, had to be transported via an exterior makeshift lift. The house was colourful. The entry to the top floor was narrow like you have to squeeze through the narrow pile of stairs.Many people were climbing the stairs to explore the house.The stairs looked unevenly placed but on closer inspection, there was always a way to climb that stair.
