Even I most likely do play well enough yet to optimise my city building plan correctly. I always feel like I get a new culture too quickly (and not always being the first) and didn't have time to build more than one unique district. 

As was able to continue producing unique units after changing culture I feel like we should still be able to build our unique district from previous cultures.

I don't know if it's a technical limitation or a balance one, but for me, it doesn't feel right as a balance one. Maybe one way to fix my problem is to allow building them for at least one era more or if they're in the queue to still allow their construction.

EQs (Emblematic Quarters) can indeed only be placed on the map during their specific Era.

There's a "trick" though : if you started building them (production already invested) and they are in your building queue when you move to the next Era, their construction can be completed on the next Era.

Before moving to the next Era, production invested in all EQs in building queue :

After moving to the next Era, 1 EQ has been built, production queue follow with the remaining 2 :

Not true, my active construction simply disappeared because it wasn't completed on transition turn.

Probably because there wasn't any production invested in the queued EQ ?

Here's turn 65, the 2nd EQ has been built in Athenai, and currently finishing the 3rd EQ

On turn 67 (or buying out the 3rd one on turn 65) :

It is clearly intended that you lose the old emblematic quarter given it say so in the select culture tooltip. Also since you lose access to all unclaimed fame stars of the past era, you don't have to rush through the eras as quickly as possible.

I tend to wait for the AI to have one star left to take my culture, but when I did not play well enough and I'm late I tend not to wait to much to avoid not getting what I need for my plan.

Thanks to confirm my feelings about that, but most of my frustration comes when I'm building a new city. As you weren't able to put a turn of production in it.

If pacing ain't improved at release and I still feel this too annoying I might try to do the mod to "fix it". 

The mayor effect is regarding territories or cities that you attach or found later on. Hence, you will never have your ancient era EQ in all modern time territories, which changes the balance of them. Not sure if it is good or bad balance wise but from a narrative stand points it is the logical approach. 

I also like that it's a trade-off regarding moving to the next age: the option to add more of a certain EQ and total fame vs. new options regarding technology, culture bonuses and directly available fame.

In summary, I'm in favor the the current approach.

I had this feeling only in the ancient and maybe sometimes in the classical era because I think those two feel somewhat shorter since you need to wait so long for or territories to be ready to go while still making progress towards the stars. I think in this case it is mostly an issue that the star requirements within those two eras might be too low. Once you have reached the medieval you should have enough production and research to get and build them quickly. 

I think the mechanic that lets you loose access to those districts is a good one because it makes cultural transcendence be an interesting choice. Otherwise transcendence  would just be strictly worse than anything else, and that discourages a variety of different play styles.

Not loosing access to the emblematic unit, as it was in the Victor OpenDev, also makes a lot of sense to me because it ensures that jumping to the next era does not immediately put you in a vulnerable position in which it is harder for you to defend yourself than it was before. EUs are also gonna out-date in the future when you get stronger units. So I think that aspect is atually fairly well balanced. I think it's mostly the pacing of the first two (full) eras that might need some adjustment
