ᐅ Are external blinds necessary on the east side?

Actually, the question can be asked more generally: On which sides do external blinds really make sense if privacy is not an issue and it is only about sun protection?

Or is it better not to differentiate, and should external blinds be installed everywhere if you are already installing them on the south and west sides? For us, the south and west sides are definitely decided on — so with external blinds.

We have mixed solutions.
North side has only roller shutters, but these are just for secondary rooms.
East side: 1 venetian blind in the living room, 1 roller shutter in the bathroom.
South side: venetian blind in the open-plan living area, roller shutters in the other rooms.
West side: 1 venetian blind in the office.

Many people mix them, and so do we. One should not forget that external venetian blinds are more susceptible to wind. That can be inconvenient, especially with the floor-to-ceiling bathroom window during storms.

We have no exterior shading on the north side. On the east side, only in the upper floor main bathroom, nowhere else.
The other building sides, which generally have significantly more glazing, are fully equipped with external venetian blinds.
So far, we have not missed any shading.

North: nothing
East: roller shutters (bedrooms, kitchen, etc.)
South: external venetian blinds (because of living spaces)
West: no windows (semi-detached house)

And yes, this is exactly right. The east side stays completely dark, which is good for falling asleep and blocking the early morning sun, the south side blocks the sun but lets light through, and the north side only has the bathroom, toilet, and utility room anyway.

For us, the east side includes the main entrance, the main hallway (from the entrance to the open living, dining, and kitchen area), and the dining area. The facade is actually slightly northeast-facing and faces the neighbor. Therefore, we are not considering any external shading options (such as venetian blinds or roller shutters) but only internal curtains for privacy.

From what I see here, in such a situation, no one would find it necessary to install expensive venetian blinds or roller shutters on the east side facing the neighbor. Bedrooms, of course, are a different matter.

On the south side (garden side), we will equip everything with venetian blinds, and probably on the west side as well. We have no windows on the north side (street side, garage).
