House Design
Who designed the plan: By me (don’t hit me!!)
What do you particularly like? Why? Living on one level (upper floor).
What do you not like? Why? Paths from living area to the garden.
Estimated cost according to architect/planner: ?
Personal price limit for the house, including equipment: 300,000
Preferred heating technology: Gas condensing boiler and solar thermal on the roof, underfloor heating, (water-bearing) wood stove

If you have to give up something, which details / extensions could you do without?
- Difficult to say

Why is the design like it is now? For example:
Whim born from boredom, professional advice has not yet taken place.

What is the most important / fundamental question about the floor plan summarized in 130 characters?
Which basics might I have completely misunderstood or insufficiently considered due to lack of expertise?

Also: Is it even possible to “bury” the house in such a way that I can access the upper part of the garden directly from the upper floor, or does the slope not allow this? (--> see “ZoningPlan.jpg”)

The blue line in the 3D views should represent the building boundaries.

Is the price not achievable even with timber frame construction?
Maybe possible with own labor? Which kind?

Never ever. At first, I thought the 300,000 € was equity ;-p

You have 3 floors with living space quality.
For 300,000 €, you can barely get 2 floors. With medium to high-end finishes, not even 2 🙂 given the site conditions.

Labor by yourself hasn’t even been considered. Or do you want to save 50,000 € just by painting?

About the budget
A general rule of thumb is 2,000 euros per square meter (approximately 185 USD per square foot)
Some manage with 1,700 euros (about 157 USD) per square meter through careful planning and saving
Additional construction-related costs apply and can be significant for a sloped site
Landscaping also tends to be more expensive on a slope

Owner participation
Try searching online for “owner participation house construction table”

Timber frame construction is not necessarily cheaper than traditional masonry. Especially since your ground floor is not timber frame

Does the house really need to be moved that far north?

Do you need all the rooms or is the workshop just filling space?

Regarding the basic layout, I am also wondering... what happens in practice?

Basically, I would place the practice area more towards the right side of the plan, facing east. On the living floor, I would position the dining, kitchen, and living areas on the left side of the plan, facing west, with a level access from the kitchen/dining area to a west-facing terrace.

I understand the staircase – but apparently the mind behind these freewheeling ideas doesn’t.

The fact that it opens into the living room then becomes just a minor detail.

Ahh... I’m banging my head, right? But that fits. It’s known to enhance thinking ability. We deliberately planned for it to open into the living room. But we’re still unsure about that.

Going through the storage room to get to the workshop seems backwards to me.

I think that would work. Besides skis, tents, and so on, we also want to store drink crates, milk, etc. There, I wouldn’t want to always have to go through the workshop.

As a painted wish list for Katja, the plan might be suitable; the rooms will probably still work in budget-appropriate smaller versions ;-)

Glad to hear that. Where and how would you reduce the size of the house if you look at the living floor upstairs? To me, it doesn’t seem overly spacious (kids’ rooms 14m2 (150 sq ft), bedroom 16m2 (170 sq ft)...) Would you rather save space in living/dining/kitchen areas?

You have 3 floors of living space. For 300k€, you’d barely get 2 floors, and with medium to high-end finishes, not even 2 🙂 considering the terrain.

I have two floors of finished living space. So that would fit then :-)

Or do you want to recover 50k€ through painting?

I’ve considered doing most of the ground floor myself since it’s not strictly needed for living at first. So moving in and then painting, laying tiles, and finishing the ground floor “comfortably and gradually.” Too crazy?

Do you need all these rooms, or is the workshop just a filler space?

So I’d have to reduce the house from about 300m2 (3,230 sq ft) to 200m2 (2,150 sq ft) to get around 300,000 euros. As asked above: how do I best go about that? The rooms are needed, including the workshop.

I’m unsure. On one hand, the building boundaries are quite far north on the plot. On the other hand, I want to be able to go outside from the upper floor... If I don’t set it deeper into the slope, that won’t work. Or are there good options for that?

Thanks for your feedback! 🙂

And on the living floor, I would put the dining/cooking/living areas on the left side of the plan, facing west… with a level access from the kitchen/dining area to a west-facing terrace.

And we will definitely take that into account. It kind of rubbed off from our current living situation. Sunrise during breakfast and all...

If you want to include the legal building aspects in the discussion, a larger section of the drawing part of the development plan and all the textual determinations would be necessary, or alternatively, references (no links) to where the plan can be viewed online.
I assume that garages are not permitted outside the designated building area. The balcony and the exterior staircase definitely are not allowed.
Is the pitched roof with a 22° angle fixed?
Do the wall heights apply to all plots alternatively, or is the building style ground-floor plus one upper floor or ground-floor plus attic floor plot-specific?
How is the height reference point defined?
The solid lines in the development plan excerpt are probably contour lines. Are there numerical elevation values available for these?
Does the terrain slope continuously, or are there significant discontinuities? The standard reference elevations at the plot corners and the building window corners would be helpful.
