Small plot and corner bungalow

Hello dear ones,

I have been reading along for some time and would now like to ask you for advice. We are still pretty much in the early phase and would actually like to build a corner bungalow with about 115-120 sqm of living space (for 4 people). The plot we have in mind has a size of 547 sqm.
However, I have some concerns that the plot might be too small for our plans. The plot should still have space for a carport for 2-3 cars, a pool (max. 3x5m), a wooden shed (for bicycles, garden tools, etc., max. 4x4m), and a sandbox. My partner and I do not place much value on gardening, but the above-mentioned things should definitely have enough space.

What do you think? Is it doable?

How wide is the property? At the bottom it is 15.67 m? And at the top?

Slope location? Building window limited downwards?

At first glance, that sounds ambitious. And why a carport for up to 3 cars?

Maybe you could sketch roughly how you imagine the layout.

The plot is 18.10m wide at the top. It does not have a direct slope location but is slightly higher at the front than at the back. However, we would actually like to level it so that it becomes flat. The building envelope is not limited. The 3rd carport space would possibly be for the child's car so that it does not have to be parked on the street. But it is rather optional. Two spaces would be completely fine. We have already roughly sketched it. At first glance, it looked okay in terms of space. Nevertheless, I wanted to ask here for advice once again. It is our first (and hopefully only) house that we are building.

Then just post the sketch.

Do you have to observe a floor area ratio?

Please don’t laugh. That was my very first attempt. I know there is no corner bungalow in the picture, but that’s how we imagined the layout. The terrace should, of course, be located in the corner. At the front, we only want to keep the 3m, so that the least amount of space is wasted.

The floor area ratio is 0.3 = 164.1. So it would be allowed.

Best regards
