Floor plan single-family house, 140 sqm with basement

Hello,
I have been following here for a while and have already gathered some good ideas.
Today, I would like to ask you about our floor plan.

We are building on a relatively small plot. Therefore, we decided to build with a basement, as my wife and I both work from home and therefore need an office.

Since we have planned for children, we also need space for them.

Here is the completed questionnaire:

Bebauungsplan/Einschränkungen

Edge development: yes
Number of parking spaces: 2
Number of floors: II
Roof shape: SD max 45°, PD, ZD max 30°
Style: basically masonry, plaster or wooden facades permitted

Maximum heights/limits: GH max 9.5, TH max 4.5

Why did the design turn out the way it is now? For example
The plan was based on a house we liked. However, it had to be smaller and with a basement. Initially, the stairs were swapped. But we did not like that the children always had to go through the living room.

Additionally, a laundry chute was added, and the fireplace was moved from the corner where the laundry chute is now to its current position.

For this reason, a storage room was added on the upper floor (by the stairs). We don’t like it because it blocks the light for the hallway.

For my taste, little to complain about. (Except that my preferences are different ) (Cooking/Eating on the terrace, living more in the retreat area)

The stairs from the basement now end in the living room. Will there be a door there? I would recommend that.

Laundry chute, I would place it so that it is accessible from the upper floor hallway (that should actually work and could extend down to the basement). Then the children don’t have to use the parents’ dressing room, but the laundry chute in the hallway wall to the dressing room can be used by everyone.

Regarding the kitchen planning .. make sure the floor-to-ceiling window is positioned so that the distance between the cooking island and the row does not exceed 120 cm. In general, a cooking island could be too small, hardly any space to put pots around it, the room is only 324 cm wide ... the more I look at it, the more I would place the kitchen completely differently in the room. Just a few quick notes: base cabinets at the bottom of the plan, so then no window at the bottom of the plan, cooktop row on the left side of the plan, sink island in the middle with a bench between the floor-to-ceiling windows on the right. I can sketch this more precisely if needed.

For a house without a basement, I would really like the floor plan.

What I don’t like, however, is the access to the basement through the living room and the gigantic storage room on the ground floor, which would probably suffice as a utility/house connection room in a house without a basement, but here is completely oversized thanks to the basement.

These "problems" probably come from transferring the floor plan of a house without a basement to a design with a basement.

Hi,
thank you very much for the quick responses.
The storage room is really quite large. We marked it out in our apartment yesterday and were a bit shocked. It is too big. And yes, in the house that serves as a template, the building services are located there.

Unfortunately, it is already relatively narrow. To make it smaller, you can only enlarge the living room and make it even narrower, right?

Moving the laundry chute to the hallway is definitely a great idea. I don’t want to have to walk through all the rooms later to collect the laundry if the kids can do it themselves.

In our house model, the kitchen is also designed differently. There, the stove is at the bottom next to the sink, so the kitchen island is more of a bar. But we are still completely free here. A sketched idea would certainly be helpful.

Thank you very much in advance.

A really nice floor plan, I would possibly swap the WC and shower on the upper floor so that moisture is not directly at the door.

Hello,

overall a nice floor plan.

However, I would still consider the following points:

Shower in the bathroom on the ground floor:
Wouldn't it make sense to make the niche exactly the size so that the shower fits perfectly and then only a glass door is needed at the front – instead of a two-sided shower enclosure as required according to the plan?

Storage room on the ground floor:
As already mentioned several times, slightly oversized for a house with a basement.

Bathroom on the upper floor:
The distance between the end of the sinks and the 2m line seems a bit tight to me – how tall are you? At 190cm +, one could quickly hit their head if they take just one step back.

Child2:
The door is positioned somewhat awkwardly. If you open it with momentum, it slams into the roof at just over 90°. To avoid this, you would have to screw a doorstop basically "in the middle of the room" onto the floor (tripping hazard) or onto the roof (an acquired taste visually).

Bedroom:
Here, I would consider whether I really need the wall between the sleeping area and the dressing room, or whether I could achieve the room separation with a built-in floor-to-ceiling wardrobe. This saves money and space.

Finally, one more question:
Are you perhaps considering a photovoltaic system?
As currently planned, your fireplace is on the southern half of the roof. If a photovoltaic system is considered, the issue of shading and thus reduced performance of the entire system should definitely be kept in mind.

Regards,

Dirk
