Bungalow planned on existing basement: ideas?

What do you notice about the floor plan?

That there are no walls? Scale unknown and flexible? The wardrobe is bigger than the kitchen and bedroom closet combined? Maybe you should fill out the pinned questionnaire for floor plan discussions here and use graph paper where one square equals 50cm. Thanks

The staircase is predetermined, so we planned a bungalow around it. What do you notice about the floor plan?

Why around and not on a basement, what is the unfortunately not-to-scale drawing supposed to represent at all: the floor plan of the lower floor aka "basement" or that of the bungalow built on top of it? What obviously stands out is that there is no staircase to be seen at all - at most the position of a staircase (from what kind of staircase is that supposed to be, which is apparently smaller than the guest WC?). Even for a halted construction, there should be more than just a child's drawing of the existing structure - by the way also one of the back then planned above-ground building part. As much as I am a fan of reusing (suitable!) basements, I still advise against considering the contamination of a property with a ruin - and what has already celebrated its ten-year anniversary as a lost place can hardly be anything else! - as anything even remotely other than a legacy burden, just because the substance in the layman's opinion (in this sense inexperienced architects are also laymen!) is supposedly not or at least not visibly scrap. "Location, location, location" may in individual cases also apply only to a limited extent, and I see that as given here.

Many thanks for your feedback I actually did not read the comment. I will revise my drawing. I have all the documents etc. and the floor plan is a 1:1 copy of the basement. Hand-drawn and built the way we like it. Also thanks for the critical comment regarding the basement: Actually off-topic here but gladly: What problems would you expect with the lost place? As a layman, I am already trying to read up on it a bit, for example, the stone used is not damaged by permanent moisture.

I would have concerns about water and frost damage.

What do you mean by age-appropriate?

Regardless of the dimensions.
Separate spa area and sleeping.
Not that the clothes smell like infusions or, despite controlled residential ventilation, moisture remains in the wardrobe.
Direct access to whirlpool - spa

Guest/children's bathroom lacks a window.

Very large wardrobe

Open-plan room.
Kitchen feels quite small
Table blocks terrace access
Please draw chairs, and make it look like someone is sitting on them.
Sofa stands in the middle of the room.
The room is a good example that size is not everything

I can’t find any “off topic” at the core of the issue. Vacancy actually accelerates any decay – and here the shell construction has basically even experienced a “first occupancy” through vacancy, which probably hasn’t “seasoned it dry.” A self-regenerating stone crosses the line from wishful thinking to nonsense. What should have impregnated it that thoroughly? Ten years without adequate weather protection – i.e. not only precipitation events but also climate fluctuations over days and years – take their toll on every building. That this unplanned long-term exposure test would be shrugged off without a blink, even a layman can hardly seriously believe. Furthermore: if this really is such a prime location, in ten years you’ll hardly be the first to smell a bargain in the property. Don’t you wonder why your predecessors ultimately weren’t the fools? At least demolition contractors, drying specialists, appraisers, and other professionals would have been predestined property developers here. Without a boil, this sleeping beauty would have long since been under the hood.

Thank you for the suggestion. Since it is not to scale, it looks very unbalanced. I will revise it again.
The guest WC/children's bathroom should get a skylight. It will be a bungalow with a flat roof.
But yes, maybe there are better options! Thanks for that!
