Look for Wohnungsgenossenschaft or Wohnungsbaugenossenschaft. They are relatively common in Germany and Austria; Vienna is an example where the majority of flats are owned by such cooperatives. In Hamburg roughly 14% of all flats in the city are being provided by cooperatives which has huge advantages for those who get to become members.
All sources I know are in German language so if you want to read further just go for these texts and translate them into your mother tongue. Maybe start with Wikipedia:
There’s an alternative missing in all these graphics: Feet not on the ground.
If your feet are on the ground for hours and hours your heart will be in trouble to pump the blood back up all the way. It’s even worse with standing. So see to that your feet are not on the ground, rest your legs on some support under the table, sit cross legged (it’s feasible even in office chairs) and take every pose that’s not feet in the ground.
Your venes and your heart will thank you.
