ᐅ Bungalow Floor Plan Approximately 140-150 m² – Requesting Feedback

Hello dear housebuilding community,

A friend and I are currently working on the topic of building a house. We already have some offers, but we are still struggling to find a suitable plot of land (so there are no details about the plot further below).

We have received a very good offer for a house (Massa Haus – Lifestyle 33 V1), and we are currently experimenting with the floor plan. Almost everything has been changed: the house was mirrored and rotated, the entrance relocated, and the living area swapped with the bedrooms. We are generally satisfied with the result. However, I think there is still potential for improvement to make the rooms feel more inviting. Especially for the long hallway, I currently have no ideas except for a narrow window between the living room and hallway to let in at least a little daylight. :-)

Since I lack comparison options, I would like to get your opinion on, among other things, the following points:

1. Is the children’s room (bottom right) too large at 18 m² (194 sq ft)?
2. What are some ways to make the hallway feel more welcoming? Widening it?
3. Is the area for the living room, dining room, and kitchen sufficiently sized, or is there anything that might interfere with furniture layout?
4. Are there any "no-go’s" in the floor plan? Do you see any wasted space or poorly positioned rooms?
