Sweden is very green and comparatively car free. Having open windows during summer to let in light, fresh air and bird sound is culturally strong here.

You can buy curtains, you can't retroactively insert a window as easily nor should you have to my lord.

I can't imagine living in a dark, centrally ventilated container. Most Swedes agree (massive pushback when this happened, gov backtracked).

No, you are right. It is absurd. The same government also increased the income tax deduction on renovations both in percentage and amount.

So is the suggestion of less light and more isolation in Sweden. One of the darkest and most lonely countries in the world. There is already no requirement for windows in bathrooms and kitchens, as you can't regularly open windows in winter anyway.
