If you want the bedrooms downstairs, then the bathroom is unfortunately badly located there, as Haydee and YPG have already explained after me.
Neither bedrooms upstairs nor downstairs can be furnished and used well according to the house size. Upstairs you will have problems with the wardrobe position, sloping roof, etc., the room will feel awkward, downstairs it is similar problems.
What do you mean by often .. because of visitors? Wouldn't it be smarter to design living/sofa/TV solo and instead have a spacious kitchen/dining area, whereby the cooking area can also be a bit more secluded. But then you can also use a table situation really well, because even a nice table for 6 people already takes up space.
And, when you speak of east or west or whatever, then please only if you also grant the plan a north arrow sometimes, otherwise it is always better to write from plan-right, plan-left, etc. Because left and right is definite ;) ;).
It hadn't even occurred to us so far that the bathroom should/must be next to the bedroom.
Do you maybe have an idea how it could be done differently for us? ;)
A separate kitchen is an explicit wish of my wife because she can't stand cooking smells.
A sliding door between kitchen and living room is still up for debate.
I did mark the cardinal directions and house entrance on the site plan after all. :p
That is a good hint about the location. According to that, the living room faces east and only gets a small window to the south. I imagine that to be dark. Since I don't know the plot, I can't say anything about the location. East-west orientation is generally not my first preference.
The kitchen as a living space gets reasonably good light – overall, I would make the openings significantly larger because I'm somewhat of a light fanatic. It can become very nice.
The children's rooms will not be too large. They can be well structured – school, sleeping, and playing do not compete with each other in one room. Teenagers will later have the opportunity to hang out together indoors. I like that.
Since it is unclear how your life runs and what kind of people you are, it's difficult to give specific tips. How will the living room be used? Where does life take place in which time of day and year? What are the needs for sociability and retreat? Which hobbies need to be considered? What is the relationship between house and inhabitants to the property/garden – or how is indoor and outdoor life practically connected? How do you feel about keeping the house clean (if that's a hobby, size and longer travel distances work well for you...). How important are operating costs? What is the preferred furnishing style (and how does this fit the spatial generosity)?
The already mentioned location of the toilet to the master bedroom is less favorable for people needing privacy.
I would definitely look at the issue of daylight in the rooms more closely again; it seems rather low.
This sounds very optimistic to me, I would have guessed about four times as much just on gut feeling – especially since large rooms also require a greater ceiling height to have a positive effect and offer living comfort. I have a friend with a 90sqm living room with 2.8m ceiling height. I feel both lost and oppressed there at the same time. With large rooms, I think of space to let the furnishing work. The standard price segment offers little choice here and is designed for standard room sizes. Since the budget suggests that money is not a generously available resource, I would take that into account during planning.
Overall, I don't quite understand the information. The drawing is professional and serious and just does not seem to fit the budget without further information; after all, Poland is no longer a cheap country and is also subject to some expensive EU standards in construction.
As said, we want to enlarge the terrace doors as well as the east window in the living room.
A living room in the west would probably have been better, but there we have a forest path and thus less privacy.
We are often in the garden during the warmer months, tinkering and enjoying the weather. The lawn has to be mowed, but that takes about 2 hours every 1-2 weeks.
Luckily, I have largely automated the irrigation. For hobbies that need a lot of space, we have a workshop in the outbuilding.
I don't know what our furnishing style is called; we like a lot of wood but no "heavy" wooden furniture.
For operating costs, I calculate about 2500 euros/year, but after the house is built we will counteract this with a photovoltaic system to bring these down to zero.
We will definitely look at the daylight situation room by room again!
We are lucky that we have several tile, window, parquet, and furniture manufacturers within 20-30 km and can thus source a lot locally and cheaply.
Furniture is definitely planned so that it does not "get lost" in the room.
Wages in Poland have more than doubled in the last 15 years, but they are still about one third of what you earn in Germany. Thus, services are especially much cheaper here than in Germany. As an example: two years ago a 3-year-old house with 150 sqm plus 3000 sqm plot right by a nature reserve was sold nearby for 80,000 euros.
The budget will work out. We have already fenced the plot. In the outbuilding, we have already installed all the utilities, i.e., water, electricity, heat pump (including well and drilling). For the house, we only need to plan a second heat pump module here.
