Buildings
Hello Swabians and everyone else who wants to know how to make your base more beautiful without going broke. Here's the bad news: you'll go broke. It takes a lot of resources to expand and it takes patience. In this short guide you'll find some tips on how to speed up the expansion, what you need and a list of which buildings you should upgrade and in which order.
What is the goal?
The goal is simple. We want to have all buildings at maximum level. Some buildings are more important because they help you achieve this goal, and some are not quite as important. A big aspect is the procurement of materials for the expansion, so depending on the level we focus a little more on strengthening the troops, in other level areas a little more on building other buildings.
How do we expand our buildings?
The maximum level of each building is defined by the level of the headquarters. If this is level 23, for example, all other buildings can also be upgraded to a maximum of level 23. If there are enough materials (iron, food, gold) to upgrade a building, the building is marked with a green arrow. Click on it, upgrade, wait until it's finished.
Is there a faster way?
Of course. There are four ways to speed up.
The Craftsman Hut is the basis of acceleration through its free acceleration time. This should always be at the maximum level to speed up all further construction.
Alliance support is a central component. Whenever you start an upgrade, you should request alliance support.
Next, you can use the construction accelerators 
or universal accelerators 
. However, this should only be done after all alliance support has been received.
On the other hand, you can reduce the construction time by taking an official position (Secretary of Development = 50%, Secretary of Science = 25%). The best thing to do is to look at the Guide Capitol Ministries. There you will also find an explanation of the acceleration calculation.
Where is the chalk line, or the common thread?
The common thread is the leveling of the headquarters, so here is the table that everyone probably already knows anyway. Let's ignore the first 7 levels because they are already pretty well managed in the game. It is important to see that every headquarters upgrade has certain requirements. From level 7, the 1st Tech Center 
must always correspond to the level of the Headquarters 
. In addition, depending on the level, the Alliance Center 
, the Tank Center 
, a training ground 
, a barracks 
or the wall must correspond to the level of the Headquarters . Just look in the list. This will give you the first clear dependencies in the further development of the base.
In terms of the requirements, it is of secondary importance whether you always keep the relevant buildings at the same level as the headquarters or whether you carry out the most urgent upgrades in steps of four. This should also depend on how many buildings you can carry out in parallel. If there are few, I would always keep all of the above buildings at the maximum level, if there are many, I would work in stages.
What else is important?
Resources
The supply of resources is also important, because without them you cannot build. At low levels, the guided activities in the game are sufficient to obtain enough resources for the expansion. In the level range up to about 12, the upgrades should flow into gold mines 
, farmland 
, iron mines 
, training bases 
, smelter 
and material workshops 
in order to create the basic stock of resources.
From about level 12, you will no longer get enough material with the resources you have grown yourself to continue building efficiently. A new source of raw materials is needed and that is your heroes, who are involved in various battles and events provide the necessary materials. From this point on, you can upgrade the buildings you produce as you wish. For example, on city building day for the alliance duel - they use little time or resources to upgrade, so you can get them up to a good level pretty quickly to gain a few extra points in the duel. From around level 24, you should start saving, especially gold 
becomes scarce. From here on, the focus should be exclusively on the buildings that are necessary for reaching the next level.
The smelter is a small exception - this should always remain at the max level, as the upgrade ores 
produced will never be enough.
Buildings for hero improvement
As written in the previous section, from level 12 onwards you need a lot more of your heroes to get the necessary materials for further expansion. So let's take a closer look at these buildings:
Here we have the tank center , which you always have to follow anyway due to the red thread. We have the aircraft center 
and the missile vehicle center 
. Both are important because, in addition to building power, they provide something for your heroes: troop capacity, HP and ATK power for the corresponding hero types. This makes a big difference in the combat power of your heroes, but if you don't have any heroes of the corresponding type, the influence is not so relevant. If you have a hero at five stars, the corresponding center is more important again, as further upgrades (Wall of Honor) are only available from level 20 of the respective center. For aircraft and missile vehicle center , I recommend attaching both to the maximum level of the headquarters from level 20.
Barracks, training grounds and hospitals
One thing at a time. You need barracks to train troops. These are connected to the upgrades of the headquarters anyway. But there is more than one barracks . Read through this trick and adjust your barracks to the level of the respective situation so that you can train the corresponding troop tier.
There are also several training grounds , but here the level of the training ground determines the maximum number of troops you can have. Which in turn means how much combat power you have and how many troop losses you can tolerate. You definitely have to make more space available here than the maximum troop capacity of all your heroes, otherwise you will limit your combat power.
Rule of thumb: for each headquarters level, you should provide 1000 soldiers capacity on the drill grounds .
There are also several hospitals. And at least one of them depends on the thread, so it should be increased with each level. However, there is another aspect, namely the capacity of the hospitals. If a hospital 
is full and you have no hospital capacity available in battle, your soldiers die and you have to train new ones - this costs time and money, so make sure you always have enough capacity by keeping the first hospital at the max. level and upgrading the others flexibly.
There is also a rule of thumb for this: for each headquarters level, you should provide a hospital capacity of 333 soldiers. This corresponds to a third of your total number of soldiers.
Component factory and equipment factory
Both are extremely important. The equipment factory 
produces weapons, etc. to improve your heroes' equipment. During low levels, the level of the equipment factory is not particularly relevant. But when you have collected enough epic equipment (equipment level 40), the equipment factory must be at level 20 to be able to use the blueprints for further upgrades.
The component factory 
is similar, it produces drone components. Not particularly relevant at the beginning, but from Headquarters level 15 onwards this should also be brought to maximum level.
Garages
You can ignore your troops' garages. These bring combat power and the speed of your troops during troop movements is not quite as important for someone who has time.
Other buildings
There are not many other buildings left now. You can always upgrade them if you feel like it and have too many resources or if you are running low on points for the duel.
Dekorative Buildings
On top of the buildings described, there are decorative buildings available in game, improving your strength and other attributes. Please check out this guide to learn more.
Season 1
At the beginning of Season 1 there will be additional buildings which will be explained in the corresponding guides. On the one hand, the professional hall, on the other hand, the season-specific buildings which are removed after the season.
Summary
I hope you are not disappointed that there is no clear guide telling you which building to upgrade in which order. Since the upgrades are always very situational and react to different circumstances, it was important to me to convey a basic understanding of the building types and to shed some light on the dependencies. I hope I have succeeded in conveying the basics to you and enabling you to make a good decision yourself about which building you will upgrade next.

4 x Lazarett auf Lv 27 (mehr geht bei HQ 28 bei mir nicht) = 7.520
Ich weiß, über Forschung und Allianz lässt sich das noch steigern, aber um 2.000 Plätze?
Danke dir :)
ist wie geschrieben eine Faustformel, also so um die 333 pro HQ Level. Aber schauen wir mal kurz in die Rechnung. Das Spital beginnt mit einer Basiskapazität von 800 und erhöht sich je HQ Level um 40. also sind wir nach 30 Leveln bei genau 2000 pro Spital. Als erstes addieren wir die zusätzliche Kapazität, welche durch die Überlebenden dazu kommen (bis zu 25 pro Überlebenden bei vollem Sternelevel). Pro Spital ist das eine maximale Erhöhung der Kapazität um 100, da es ja vier Überlebende pro Spital sind. Jetzt kommt die Forschung oben drauf. Hier insbesondere nennenswert die Erweiterungen des Krankenbettes 1 - 4 im Bereich Entwicklung. Diese werden aufaddiert und die Gesamtprozentzahl auf die Kapazität aufgeschlagen. Die Erweiterungen 1 bis 3 jeweils bis zu 5% und die Erweiterung 4 mit bis zu 10%. Bringt also 25%. Im Bereich Verteidigungsbau kommen dann noch mal bis zu 10% oben drauf. Heisst dort ebenfalls Erweiterung des Krankenbettes. Es ist davon auszugehen, dass danach noch weitere Erweiterungen folgen, diese sehe ich aber bislang nicht
Also ist unsere Formel gleich (4 Spitäler * (800 Basis + ( 40 mal HQ Level) + 100 von Überlebenden)) + (5 + 5 + 5 + 10 + 10)% = 11340. Das macht einen individuellen Maxwert von 378 Betten pro HQ Level Der Wert wird abgerundet...
Einen Einfluss auf die Spitalkapazität durch Allianzforschung oder Dekorationen gibt es zum aktuellen Stand leider nicht, heisst aber im Umkehrschluss, dass Du diese Zahl absolut ohne fremde Hilfe erreichen kannst. Noch ein kleiner Hinweis, wenn Du auf dem Spital auf Upgrade tippst, wird die die aktuelle Kapazität und die Kapazität nach dem Upgrade angezeigt. Das sind aber nur die Basiswerte ohne Überlebende und ohne Forschung. Die zusätzliche Kapazität durch die Überlebenden findest Du in der Überlebenden Liste. Die Gesamtkapazität je Spital findest Du wenn Du das Spital antippst und dann auf die Linke Taste klickst.
Viel Spass beim nachrechnen :) und weiterhin viel Erfolg und Freude am Spiel
Gruss
