Designing an open space interior with a round TV unit to serve the entire living room and a large bedroom with a spacious dressing area can create a stylish and functional environment. Here's a suggested layout and design elements for such a space:

Overall Layout:

Divide the open space into distinct zones: living area, dining area, and bedroom area.
Use furniture placement and room dividers to create visual separation between the zones while maintaining an open feel.
Consider using a circular or curved arrangement for the TV unit to allow for better viewing angles from different areas of the room.
Living Area:

Place the round TV unit in the center of the living area, serving as a focal point and providing entertainment to both the living and bedroom areas.
Surround the TV unit with a comfortable seating arrangement, such as a curved sectional sofa or a combination of sofas and armchairs, allowing people to enjoy the TV from various angles.
Incorporate a coffee table or ottomans in front of the seating for convenience and a place to put drinks or snacks.
Dining Area:

Position the dining area adjacent to the living area, creating a seamless transition between the two zones.
Choose a dining table that complements the overall design and size of the space. A round or oval table can echo the circular theme of the TV unit.
Select dining chairs that are comfortable and visually appealing. Consider upholstered chairs or chairs with curved lines to enhance the cohesive design.
Bedroom Area:

Place the bed against a wall that is opposite the living area to maximize privacy and separation.
Incorporate a large dressing area next to the bedroom, which can include a spacious wardrobe, a vanity or dressing table, and a full-length mirror.
Utilize built-in storage solutions, such as floor-to-ceiling wardrobes or custom closets, to optimize space and keep the area organized.
Lighting and Decor:

Install adjustable lighting fixtures throughout the space to provide flexibility and enhance the ambiance. Consider using dimmable lights to create different moods.
Incorporate decorative elements, such as artwork, sculptures, or plants, to add personality and visual interest to the space.
Choose a color scheme that suits your preferences and creates a cohesive look. Consider using a neutral base with pops of color through accessories or accent walls.
