We are planning to build a stilt+first floor. We are planning on leaving the stilt(ground floor) for parking space. But there is nearly 500sq ft left after parking space which we can use for something else. We dont want to start our house in that area. What else can that space be utilised for? Currently all we can think of is just build a room. But is there anything in specific we can utilise that space for? It will be covered area as we are building our house over it and it will have the stairs to the first floor.
