So, here is a little experience report from someone who initially sang the same tunes in this forum. Simple and without frills, we are not doing an inspection, etc.
Conclusion:
The house has become a bit bigger. You would be surprised what half a meter more makes. Yes, it costs, but it’s really worth it.
Of course, we did an inspection. For the main bathroom, we just couldn’t warm up to the standard. Especially not when such beautiful things are hanging in the showroom. And I am really tough on that kind of thing. Then there was something on top of the roof shingles (we just didn’t have that on our radar), and we also didn’t realize that a walk-in shower is significantly more expensive. We only ended up with 4k more.
Power outlets: we ended up with 80. And I was really stingy. Don’t forget to ask about network and TV/satellite outlets. For us, those were only partially included.
Entrance: We absolutely wanted a nice shelter so that we can get from the car into the house with dry feet. In the end, we reduced it to a recessed entrance and about 2 meters of walking distance from the carport to the entrance. What can I say ... that is more than enough! I can stand there comfortably in the dry and wait for the cat divers to trot by in the evening.
Hallway: We only have one child so far. But I already love our spacious hallway. We didn’t even know we missed it. It worked fine without it for years. But here I can easily push the child in including the stroller in and take it apart. The little one can safely walk 2 meters before I have to remind him to take off the dirty shoes. Guess how practical that will be with 3 children plus groceries. You also prefer to welcome guests in the hallway rather than having to guide them through the carport or a side entrance.
Third child’s room: Don’t stress so much about planning the room now. Rather set up a guest room in such a way that it can be converted into a child’s room. Then you won’t have a guest room anymore, but so what? You are building the house for yourselves, not for the guests. If the third child does not come, it remains the guest room. But you stay flexible for family planning. On 10x10m you just have to limit yourself.
Utility room: It is really very tight. We have 8 sqm and it’s enough for the ventilation system, heat pump, washing machine and dryer, connections, and a generously sized cat litter box. Oh yes, and a shoe rack. But that was it. I’m really glad to have my 4 sqm storage room.
Ventilation system: Do you really want to build without one? How will you ventilate then? Surely you won’t be opening the windows every 2 hours, right? Are you building to any KfW standard?
Stairs: Don’t underestimate the importance of these few steps. You use them several times a day. Sometimes more, sometimes less loaded.
Suggestion: Would it be an idea to place the staircase to the upper floor in the living area and then design it very openly upwards, basically creating a gallery?
