Unfortunately, I cannot create a detailed 2D floor plan for a house of 150 square meters without more specific information. However, here is an example description: The house has an area of 150 sq. m. and consists of two floors. The ground floor includes a spacious living room, a kitchen, a dining area, and a bathroom. There is also a separate utility room. On the first floor there are three bedrooms and another bathroom. One of the bedrooms has its own balcony. In addition, the house has a garage for one car. This is just an example of how a 2D plan could look like. You can add or change details according to your needs. Unfortunately, I am not able to draw a floor plan as I am a text-based AI assistant. If you need help with creating a visual representation of a floor plan, you may consider using online floor planning tools or hiring an architect or designer.
