Heating terrace area / windbreak?

One with large folding doors that are open on 2 or even 3 sides in the summer and closed when it’s cold. Then you can also heat nicely. As the OP wrote the introduction, she is quite sensitive to the cold. And it will probably be used more often than just during the transitional season.

Nobody needs something like that – especially not to extend living space outdoors on colder days.

My thoughts exactly :)
If you design the living space to be bright and cozy, with beautiful views and sightlines towards the garden, then you don’t need the appendage of "some enclosed gardens," which are only good for storing secondary furniture. An example of how broken your living space planning can be is clearly visible here – neither area is optimal. Even rather counterproductive in design.

Attached conservatories can shake hands with urinals and saunas in basements from the 80s. Often just planned as an extension of space because a lot of nonsense was built in the living room, either too small or too uncomfortable. Many just needed to make use of their home savings contract somehow.

But well: to each their own. Whoever wants to extend a used property should do so. But this is about a terrace where you don’t want to freeze, right?
The ecological stamp hasn’t arrived there yet ;)

At least the electricity comes from the battery charged by the sun during the day.

I’m laughing myself silly at this list of outdated insignia from previous generations of homeowners! Although: such an attached conservatory can really enhance old houses. I know plenty of men who would like to have urinals but couldn’t get them approved (I didn’t want one). A sauna is a wonderful thing even if there is only space in the basement – OK, my preferred place is the garden with a view of the valley and no strangers looking in.

In 40 years, the list will be: cramped dressing rooms, tiny pantries, squeezed-in home offices, vinyl floors, and noisy heat pumps... yuck, like the 20s!

And kitchens that don’t work at the front and are too small at the back (called backup). ;)

Implementation on our terrace - the black elongated thing in the ceiling is enough for the seating area.
