Hi vaivadr,

I think a simple solution would be to put a quarter turn on the steps and then move the WC further back. That will give you a much more spacious entrance. In a small place like this you need to minimise the amount of corridors so I would make the corridor smaller and give more space to the kitchen.

I would move the kitchen to the other side because you have much better option on that side with the much longer wall. I would use the space where the kitchen is now as the dining area with bench seating to save space, providing seating for up to 6. This will now allow you to open up the entire back wall with bi fold doors. Filling the house with natural light. I would add a long island with bar stool seating in parallel to the kitchen rather than peninsular as that will add to the illusion of depth to the house making it feel more spacious. The remaining area would be the lounge.

This layout gives you a more usable front entrance and gives you a lot of flexibility with regards to your kitchen size, for example if you prefer a bigger kitchen you could extend it further into the living area and vice versa. It also means you are free to remove the back wall and bring the outdoors in with a large bi fold door, producing a spacious light filled home.
