Appartamento di nuova costruzione

I prepared two design alternatives for you, each placing the kitchen in a different location. The other spaces remain roughly in their original positions, but with new layouts and revised proportions. Choosing between the two depends entirely on your preference.
In Alternative 1, I placed the kitchen near the entrance to allow for a larger and more functional living room. I designed the kitchen with an island, making it an open kitchen. However, with the same layout, you can easily turn it into a closed kitchen if you prefer: you can extend the wall behind the stove to the end of the island, remove the island and replace it with cabinetry, and add a sliding glass door for the kitchen.
The living room is open and includes a corner sofa and a dining table. I also added a storage cabinet for tableware next to the dining area, positioned behind the shower wall. As you requested, I included a study corner in the living room and aligned it with the TV wall so it integrates smoothly with the overall furniture layout. The TV wall is designed as a unified decorative element: the TV sits at the center, with a study desk and upper shelving on one side, and storage shelves or a cabinet on the other. This way, when you’re not using the study area, you can even turn the study chair toward the sofa and visually connect it with the rest of the living space.
The rest of the apartment follows the general structure of your previous layout, but I adjusted dimensions so I could recess the shared wall between the living room and the first bathroom. This small setback helps open up the dining area and define it more clearly.
In the second bathroom, I allocated space for the washing machine, dryer, and a small counter or platform you may need.
In the small bedroom, besides the bed, wardrobe, and desk, I added a sofa so that you can also use this room as a guest sleeping area.
In Alternative 2, similar to the first option, a wardrobe is placed at the entrance. The dining table and the storage cabinet for tableware are also positioned near the entrance. In this configuration, the living room is slightly smaller than in Alternative 1, and the TV wall is relocated to the back of the bathroom. It includes two shelves on either side of the TV, which you can use in any way you prefer.
The kitchen remains in the same location and general configuration as in your original layout. I arranged the cabinetry, and it is designed as a closed kitchen, slightly smaller than in the first alternative.
In the space between the kitchen and the hallway leading to the private rooms, I placed a study desk to show that this area can also function as a small workspace with proper lighting, or it can be used as shelving for household items. In this alternative, I enlarged the main bedroom and positioned the study desk inside the room, next to the window where it receives good natural light. So depending on your preference—whether you want the study area inside the bedroom or in the intermediate zone, and how much storage you need—you can arrange these spaces in the way that suits your lifestyle.
In this version, the washing machine and dryer are placed in the first bathroom, which has been designed larger.
In the hallway, between the protruding structural columns, I designed a 20-cm-deep built-in shelf that both makes use of this area and helps conceal the column projections. Considering the width of the corridor, this depth can easily be increased to around 35 cm or 45, allowing the shelf to function as a small library or a decorative display.
I hope these designs meet your expectations and that you find an alternative that suits your needs.
