Single-family house 220 sqm with basement on 700 sqm plot

Thank you very much for the valuable feedback... The advantage is that we can have the walls where we want them... The statics allow it, so why not? The exhaust pipe for the gas does not go straight up but is routed, the technology allows it.

The statics do not allow it for Ömmesöns, but fine: for all I care, build the upper floor round as well.

The hallway on the upper floor could use some daylight. I would paint the narrow corner in the utility room and assign it to the staircase, and install a window there.

Good point, thanks!

That was our original plan as well. But since we have a sloping roof above the upper floor (over part of it), we will extend the hallway all the way up and have plenty of daylight through the Velux windows. At the staircase, we only left it out for symmetry from the outside concerning the window.

Do you have any exterior views of the house? You write "FD" for the roof type and then something about a roof slope. How does that fit together? If it were a flat roof, I would find the forced symmetry even more unnecessary. What does this small recess of the upper floor look like? I don’t understand that either and wonder if it looks good. Not to mention waterproofing and additional costs.

Whether you prefer the evening sun in the living room or in the kitchen, you have to decide. What does your life look like? Where do you sit in the evenings? However, I believe you are overestimating this because the sun is only that high for a few weeks a year to shine in for so long. With which car do you bring the groceries? If it is the large one in the right garage, the kitchen including pantry/storage room on the right would make more sense. As it is now, you have a long way from the car to the kitchen and from the kitchen to the pantry. By the way, you only need it because the kitchen is too small.

Because overall you are wasting a lot of space in your new ground floor layout for this "double corridor". That must be about 25 sqm, right? I would divide that differently and rather make the kitchen a bit larger.

Good that you thought of a driveway gate at the left garage, since you will probably completely close off your property with the 2 garages on the left and right. I would also be interested in the appearance there. A small gate on the right, a large one on the left?

I don’t want to go into detail, but I’m surprised that you are so absolute.
You must do this and that because...

otherwise we can’t properly fit the stairs.

Only with this stair placement and the restrictions on ...

and technology, that wouldn’t fit upstairs. The other rooms like fitness are nice but not a must, still we want the basement also because of possible resale value and flexibility.

The fact is that you have now changed the stairs despite your statement (see above).
And the fact is also that you could accommodate the space requirements in a smaller area. However, you can afford space if you disregard the building envelope. In this respect, I wouldn’t let corset-like thoughts limit you if I were you.

Kitchen on the left side practical because of light, but no sun in the living room after 7 pm in summer?

I can’t follow that thought logically.

Price estimate according to architect/planner: 700k€ including basement, garages and ancillary building costs (without land)

If you continue like this, you’ll crack 800,000 just for the house without ancillary building costs.

If in his DIY planning the corridor keeps getting bigger to realize as many gadgets as possible in the house, he probably got himself tangled somehow.
You’re not starting anew either, you’re just changing things here and there. And with an enlargement of all rooms and the house, you of course don’t see any options because there rarely is any tightness. And hardly any gadgets are installed: I don’t even see an air space, a gallery...

At the beginning there is already the confused thought about boundary development and the garages.
The layman builds garages like elephant ears on a block house and two driveways, the architect integrates a double garage partly into the house and leaves projections which can then be used in various ways as wind protection, external appeal or waste disposal, so that an aesthetic house is created. With good planning you can also get your room program smaller. Of course, a basement may then play a role, but the basic body of the house won’t have to be oversized and bulky.

We had this idea too, it was sobering. The architects’ designs hardly gave any valuable new input here, we like this design better.

Which architects? Those of the general contractor? Forget it. They work for little pay.
With that budget and room plan, get yourself a capable architect and later the general contractor can build the house for you.
You yourself have limits, like every layman facing such a complex task.
Also the idea of building with a basement because of the resale value is somewhat off: the budget will be accordingly, and buyers also look at the money. I believe that you greatly narrow the target group with the square meter number. And you see yourself: the basement rooms are mostly just placeholders. A tool cellar may be nice, but without an outside stair you won’t start woodworking down there.

One detail:

1) Should kitchen/dining room be on the left or should the living room rather be there?

Through the entrance into the living room we practically have a reception area, through the additional passage to the kitchen we find that rather practical.

You plan a reception area with over 30 sqm of hallway space on the ground floor still in the living room... I wouldn’t plan the living room as a passage room anymore with children. I don’t think you will find it funny when watching TV if the teenagers are having their kitchen party and receive their friends right in front of your eyes. But that’s what you plan.
