Which design pattern to choose?

Question

JavaScript

There is a small map,
you can build buildings on it by clicking on free cells with the mouse.
When the map is initialized, a list of already built knowledge comes from the server:

"buildings": {
    "1": {
        "position": [2, 1],
        "type": "barrack"
    },
    "2": {
        "position": [2, 2],
        "type": "hospital"
    },
    "3": {
        "position": [0, 0],
        "type": "school",
        "size": 4
    },
}

Some buildings have a property sizeequal to 4- this means that the building occupies 4 cells.
Need:

• build buildings that came at initialization
  
• add and destroy buildings dynamically
  
• have access to the buildingid
  

I chose the factory template ( Factory ), but I don't understand it very well - where to store the whole list of buildings? In the factory module? Or make the factory part of the Building module?
Or do I need a Composite ?
I have modules:

• Map - responsible for rendering the map, and also gives out cells by coordinates
  
• The building is the building itself. It has properties: coordinate, size, if it is different from 1, a link to the image of the building
  
• Building Factory - creates buildings
  

I know that these are elementary things for gamedev, but I'm not very familiar with this yet.
