Hello everyone,

We have just purchased a plot of land and are now at the stage of planning our house.
After two initial attempts at designing it ourselves without much success, we have now met with a structural engineer who helped us create a floor plan tailored to our needs.
I would like to share this design here for discussion.
We have already chosen a local builder. The plan is for a timber frame house with solid wood interior walls and a timber frame exterior wall filled with blown-in wood fiber insulation.
The entire house is intended to meet the KfW 40+ energy efficiency standard eventually.

Owners’ Requirements

We are a small family: two adults, age 41, and one child, age 6. Our family planning is complete.
We would like a detached single-family home with two full stories, no basement, a double garage, and a storage room as a basement substitute.
The architecture should be modern, bright, with an open living/dining/kitchen area.

Architectural style, roof type, building type

- Modern
- We currently favor a gable roof with a 22° pitch.
- We also like the idea of a pyramid (hip) roof, but unfortunately, this roof type is less than ideal for installing photovoltaic panels.
- Large windows for lots of light inside, including external venetian blinds for shading.

Basement, floors
No basement, two full floors

Number of occupants, age

2 adults, 41 years old, and 1 child, 6 years old

€580,000 including plot (€65,000), landscaping, kitchen, furnishings

If you had to give up something, which details/features

Why did the design end up as it is now?

We wanted to make the best possible use of the plot.
Basically, we would have liked to orient the terrace towards the southwest, but unfortunately, there is the street there, and I don’t want to be completely exposed.
Also, the west side is the weather side with a lot of wind.

What do you think makes it especially good or bad?
???

What is the most important/fundamental question about the floor plan in 130 characters?
What do you think of the design, and what could be done differently?
We might want to redesign the bathroom, maybe a T-wall?
Would you change anything about the window layout?

We would appreciate any ideas or constructive criticism very much.

Uh... I would expect a bit more foresight from my guardian if I’m not being asked. The child spends more time in the kids’ room than you do in the bedroom,
And from the age of 14, it’s only there or not there at all, right.

It actually starts much earlier, practically from school age or when they get their first mobile phone. From 14 onwards, they spend all day lying on their bed (as long as they are at home).

I understand your concerns regarding the children’s bedroom (sleeping area), but he has the luxury of two rooms.
It’s not located in the south, but at least it is still in the nice west. What good is a nice room in the south if the exterior blinds have to be closed in the afternoon to darken the room? As I said, I understand your objections well, but it can also be seen from another perspective. Additionally, he would have peace and quiet in his room when we spend longer summer evenings outside again.

The ground floor needs to be revised, then you can swap the rooms on the upper floor. I don’t really understand your arguments.

I tried out a few changes. The living area was widened by 75cm (30 inches).
Because of this, I had to swap the guest toilet and the storage room; otherwise, the toilet wouldn’t have a window.
Upstairs, I rearranged and swapped the rooms. Now we have a larger bathroom and a bigger office,
but unfortunately no storage room. Since we are building without a basement, this might become a problem.
Above the corridor/dressing room/office, we have an attic space of about 30m² (320 sq ft), but it is only accessible via a pull-down ladder and
therefore only suitable for storing smaller items.
What do you think is better for the kids’ room? Option 1: two separate rooms (sleeping/playing) or Option 2: one large room?

When making fundamental changes, I would suggest letting go of what doesn’t work from time to time. Start fresh, do it differently, forget the hose: there are many ways to reach the goal.
