No, it wasn’t ignored; I just haven’t kept up with answering. For example, I arrive at that amount using the Sparka construction cost calculator without including the land. However, financing and other factors don’t really matter when it comes to the floor plan at this stage.

But it will become important if you create a floor plan that doesn’t fit your budget at all. Just a note.

I acknowledge that, truly. However, in this regard, we are well informed and are not approaching the matter naïvely.

I am wondering if noise can be transmitted through the laundry chute and if that makes it a poor choice to have it located in the bedroom. I imagine sounds from the utility room might then be audible in the bedroom.
Should the children then have to go through the bedroom to drop the laundry down?

Where is your building services equipment going to be installed?

DIY work still costs money, especially for materials, tools, and so on, which shouldn’t be underestimated.

2. I’ve already been struggling with this issue; I can’t make the room look nice without changing the window arrangement, which would spoil the harmonious appearance from the outside.


Well... windows are mainly for the people living inside the house. Even though I understand that the outside shouldn’t look too strange, windows should always be positioned according to the interior spaces!

5. Next to the washbasin there is a bidet planned, my wife insists on having one.


If it’s that important to your wife, then why is the bidet (along with the bathtub) not in the master bathroom, but instead in the “kids’ bathroom” or shared bathroom? That doesn’t make much sense to me.

And the master bathroom is smaller than the guest toilet?!

- Laundry chute in the master bedroom leading down to the utility room with washer and dryer.


A laundry chute in the master bathroom covers only about one-third of your laundry and only the way down. What about the kids’ clothes? And the clean laundry? Then you have to go around through the kitchen corner into the dining area, along the entire staircase, and upstairs again?! A utility room on the upper floor or an entry point for the utility room near the stairwell might be better solutions.

Further suggestions and criticism are welcome.


The upper floor looks tidier. Idea: remove the master bathroom to make the bedroom and dressing area a bit smaller, allowing the bedroom wall/K1 to shift downward on the plan and the K2/K1 wall on the left side of the plan = making K2 larger.

Also add a window in the dressing area. But I think this was already mentioned once.

Apart from the electrical distribution board, nothing else goes into the utility room.

I was thinking of placing a wardrobe set in the niche, which should be sufficient, and I find it practical to have the toilet right next door because there’s always someone needing to use it before heading out.


And the heating? Possibly a controlled ventilation system?

Do you already have the four children or are they planned? Because it feels like that wardrobe wouldn’t be enough even just for me and my partner, let alone four (!) additional children.

@ haydee
In the utility room as shown, we are opting out of controlled mechanical ventilation with heat recovery or similar systems.

@hausnrplus25
The bidet will be placed in the family bathroom since it is not needed in the master bathroom.
Is there any regulation that the guest toilet must be smaller than other bathrooms?

Then you have to go around through the kitchen, past the dining room, along the entire staircase, and back upstairs?! A utility room upstairs or an entrance utility room near the staircase would be possible solutions.

Why shouldn’t the chute be able to handle all three-thirds of the laundry?
I understand that the detour through the kitchen is not ideal, but we can live with it.

That was just an example—I can easily imagine just building in a 2m (6.5 ft) bench with hooks for jackets; usually, you only put on shoes and jackets there anyway.
