'Design a layout with one div on 2 columns and 2 rows at the left, and 4 divs on 2 columns and 2 rows at the right, similar to BBC website

I want to design a hero section similar to BBC website. I started working on this using CSS Grid which I thought could get the same design with minimal code.

enter image description here

I have managed to base design but I want item1 to take 50% of the container's width and rest of the items to take 25% of space each so that it looks like the image above. I can span rows but I am not sure how I can span columns correctly, I tried this :

.item1 {
   grid-column-end: span 2;
}

But it broke the design and same did happen with:

.item1 {
   grid-column: auto / span 2;
}

My code: 

.grid-container {
  display: grid;
  grid-template-columns: auto auto auto;
  grid-gap: 10px;
  background-color: #2196F3;
  padding: 0px;
}

.grid-container > div {
  background-color: rgba(255, 255, 255, 0.8);
  text-align: center;
  padding: 0px 0;
  font-size: 30px;
}

.item1 {
  grid-row-end: span 2;
}
.grid-container div img {width:100%; max-width:600px;}
<div class="grid-container">
  <div class="item1">
    <img src="https://dummyimage.com/600x400/f09c00/fafafa&text=1"/>
  </div>
  <div class="item2">
    <img src="https://dummyimage.com/600x400/0010f0/fafafa&text=2"/>
  </div>
  <div class="item3">
    <img src="https://dummyimage.com/600x400/5310f0/fafafa&text=3"/>
  </div>  
  <div class="item4">
    <img src="https://dummyimage.com/600x400/0010f0/fafafa&text=4"/>
  </div>
  <div class="item5">
    <img src="https://dummyimage.com/600x400/0010f0/fafafa&text=5"/>
  </div>

</div>

I will try to give You a snippet that should help You with this problem.

 // Somewhere in the code:
 std::vector<std::vector<int>> matriu;
 std::vector<std::vector<int>> usat;
 std::vector<std::vector<int>> edifici;
//

void reserva(){
    matriu = {};
    matriu.reserve(midax);
    for (int i = 0; i < midax; i++)
        matriu.push_back(std::vector<int>(miday + 1, 0));
        
    usat = {};
    usat.reserve(midax);
    for (int i = 0; i < midax; i++)
        usat.push_back(std::vector<int>(miday + 1, 0));
    
    edifici = {};
    edifici.reserve(midax);
    for (int i = 0; i < midax; i++)
        edifici.push_back(std::vector<int>(miday + 1, 0));
}

A few advices: As I wrote in the comment - try avoid using new as much as possible. It's very bug-prone. Use structures or smart pointers to avoid memory leak.

If You need to use new[], ensure that there is a corresponding delete[].

Try to code in english, it will be easier to share Your code with other people.
