House Design
Who created the planning:

- Architect
- Do-it-yourself

What do you not like? Why? Stairs and bathroom on upper floor (not yet fully designed)
Price estimate according to architect/planner: 310,000
Personal budget limit for house including fittings: 360,000 including ancillary building costs (including landscaping)
Preferred heating technology: air source heat pump

If you have to give up something, which details / extensions:
- Can do without:
- Cannot do without:

Why is the design as it is now? For example:
It was difficult to design the ground floor because the entrance should not be on the south side, so there are not many options for the ground floor layout;

What is the most important/fundamental question about the floor plan summarized in 130 characters?
Can the living area still be optimized (is the living and dining area large enough)? Ideas for the upper floor bathroom design?

Floor plan of single-family house: office, living/dining, kitchen, hallway, terrace, WC.


Basement floor plan: hall connects basement, hobby room and utility room with stairs.

Where is south?

Overall, not a disaster. Just a standard design, which doesn’t have to be bad. Without a site plan, it’s just a house.

I find the following points concerning:
- Draw the furniture to actual size. How many people can really fit at the dining table? There also needs to be space behind the chairs to move them.
- How deep are the bedroom closets? They look about 50cm (20 inches) deep – a standard depth would be 60cm (24 inches) – but the impression might be misleading.
- The wardrobe space on the ground floor for a total of 5 people is too small. I don’t immediately see a solution for this.
- Child 1 might be suffering from feeling unloved, possibly leading to depression. I would give them your bedroom and take a more modest place for myself. This could require a complete redesign, depending on the new knee wall height, bathroom size, etc. This is also something that can change over time – but it needs to be planned now.
- The door to the living room is always in the way. I would replace it with a double-leaf sliding door.
- I would add a laundry chute from the bathroom down to the basement for the convenience of the homemaker. To make space for this, the fireplace and chimney would be removed, as we need to protect the environment and CO2 will have a very bad image in the future.
- The staircase with a width of 2m (6.5 feet) is quite narrow – it fits the house and I would build it like this too – but you have to be aware of it and want it.

Thank you very much for your reply.
The terrace is planned to wrap around the southwest corner, so the entire living area (kitchen and living room) faces south.
We are currently planning the master bedroom in this location because we are not yet sure if we want one or two children. However, if we have a second child, we plan to move to the smaller room. The depth of the bedroom wardrobes is planned to be 60 cm (24 inches), that is our intention.
As I mentioned, there will be a glass sliding door to the living area, which has already been accounted for in the calculations.
A laundry chute is not very important to me.
I am not very happy with the staircase, but a straight staircase would require the house to be one meter (3 feet) longer overall, which would be too expensive. :-(

Since we have a similar floor plan, only without a basement, here is a comparison.

I find the windows quite asymmetrical, but I guess that is a matter of taste.

With a higher knee wall, the bathroom will feel a bit more spacious. That is planned, right?
I don’t fully understand the bedroom layout for the children yet: one for the 14-year-old. And if the plan includes two more, how is that supposed to work?
Could you please also upload the site plan showing the plot with the house?

Thanks for your feedback. I think the bathroom layout is a good solution for you. I’ll take a closer look at that.
The windows were chosen deliberately. For us, functionality is more important than appearance ... and we really like our front elevation with the narrow but tall windows.
