Single-family house with staggered floor, southwest location in Bonn

So I think the drawings are cool – and that the architect is thinking about the sight lines as well. He placed a lot of value on that on the ground floor.

Compared to the spaciousness of the house, I find the children's rooms pathetic. Narrow, with lots of corners and edges. Without measurements it's hard to judge, but in the sketch it looks like there is no nice corner where you could also put a 1.40m wide bed for the teenagers instead of the drawn 0.90m.

How are the 230m2 distributed between living area / terrace area and cellar area?

How are the 230m2 distributed between living area / terrace area and basement area?

230 plus basement, estimated 140sqm ground floor, 90 upper floor

What do you mean by sightlines?

In architect-designed houses, not only rooms are planned, but also the view from the living spaces. He also drew those in. That makes a big difference. The cheap standard house construction almost completely forgoes that and plans only effectively.

Even if one of the daylight rooms was intended as a play or hobby room. For model trains or table tennis.

Well, you have to want and be able to afford an indoor playground. You asked about potential savings and that definitely lies in rooms that eventually just lie fallow, are surplus or get cluttered.

But he didn't specify an exact amount, or it sounded as if the basement wouldn't make it much more expensive otherwise.

If the basement costs 150-200,000€, then the walling off naturally does not carry much weight.

We already have a lot of stuff and without a basement, I can hardly imagine it without an attic.

A house is not there to be filled with stuff. You should also occasionally part with things that are surplus. Either you can afford an architect-designed clutter floor or not. But eventually, the room distributions no longer fit.

Mediating?

You mediate: if one part grows bigger, the other must adjust or be arranged differently... a planner knows what mediating means.

but at least the terrace above the kitchen could make sense,

A roof terrace makes no sense at all if you have a garden downstairs that you have to maintain. You rather sit on the terrace near the kitchen and sip a drink because then you have to prune the branches on the trees again, or water, or dig something up. Or so.

You find our parents' area too big? We thought children's rooms with 15 sqm are sufficient

I didn't say that: I said the ratio is not right. Children's rooms are lived in, children's rooms are retreats and serve personal development. Bedrooms are mostly small palaces that exist uselessly during the day.[/QUOTE]

Save costs - paint the basement. Find the children's rooms small and cramped compared to the rest. Roof terrace no bigger than the ground floor.

So the ground floor is about 130sqm, the upper floor just under 100sqm. I'll take into account the children's rooms and whether a 140cm bed can fit in there. Our suggestion was actually once to place all the rooms on the front axis, for which we would have "given up" the en suite bathroom. The architect didn't like that and therefore his suggestion is so that the parents' area can be completely separated.

We thought children's rooms with 15 sqm are sufficient and well, eventually they are gone and then the rooms become dead space.

To define it once again: a children's room should never be just sufficient. Instead of wanting to build this disproportion because eventually... eventually when the children have moved out, these rooms can become dead space, I clearly see the dead space in a model railway room in the basement. This basement is more likely to become dead space. Eventually it gets cluttered with things no longer needed, stops being cleaned, and you live above it... just barely still use the pantry and laundry room... By the way, children’s rooms can be wonderfully converted later into grandchild rooms and sports rooms (because then there is finally time for that).

No idea why the drawings are so praised. At first glance they are nicely colorful, but much is quite hard to recognize. Measurements instead of so much color would be much better.
