ᐅ Our proposed floor plan – feedback welcome

If we decide to go ahead with a current purchase option for a plot of land, this house type with the floor plans attached below would currently be our first choice. It represents a compromise between the required rooms and the price. However, we wouldn’t want to fully adopt the floor plan 100% as is – the extent to which changes are actually possible will depend on the budget, especially considering the already quite high price per square meter here. Our room for upgrades will therefore not be very generous...

Perhaps you can give us your assessment on the following points:

1. At 152 sqm (1635 sq ft) of floor area, the house is not “small” – but we have also heard opinions that the children’s rooms are too small, the living-dining area is rather small, there is hardly any space for a play corner, and that the kitchen is too small; also the entrance area might be too small for a family of four with corresponding coats, shoes, cupboards. Does that also seem true to you at first glance?

2. I definitely want a closed kitchen and according to the general contractor, this is feasible here. But I also want a small table with 4 chairs in the kitchen. I don’t want to mess up the living room dining area every morning having breakfast with the children; I want to be able to quickly sweep the kitchen instead. I’m open for kitchen layout ideas. I’m not a master cook and it’s not a hobby for me, so I definitely don’t need a luxury kitchen with all the bells and whistles. But I really want this small table with 4 seats. Is that even possible in just under 11 sqm (118 sq ft)?

3. Since I fear the kitchen is too small for this, we had the idea to turn the 12 sqm (129 sq ft) guest room into the living room by removing the wall. The kitchen would then be extended towards the living room. Does that make sense?

4. Some comments on the floor plan mentioned that there are too few windows and that the house will not be very bright. Brightness is important to me though. Architecturally, it should be possible to add another window in the kitchen and also add skylights to the children’s rooms, right? But do you have any idea what such additional windows would cost? Are we talking around 500 euros (about 550 US dollars) or closer to 5,000 euros (about 5,500 US dollars) per window or something completely different?

Thanks for every opinion!
