Usage tips
Word structure with 'Haupt-'
The word consists of 'Haupt-' (main) and 'Gebäude' (building). The prefix 'Haupt-' means 'most important' or 'central' and is very productive in German. If you know this pattern, you can also understand words like 'Hauptbahnhof' (main train station), 'Hauptstadt' (capital city), or 'Hauptstraße' (main street).
EXAMPLE
Wir treffen uns vor dem Haupteingang des Museums.
We'll meet in front of the museum's main entrance.
Context of use
The use of the word 'Hauptgebäude' (main building) implies that there are other, usually smaller buildings, known as 'Nebengebäude' (outbuildings/annexes). It is typically used for universities, large companies, hospitals, or palace/castle complexes.
EXAMPLE
Die Bibliothek befindet sich in einem Nebengebäude hinter dem Hauptgebäude.
The library is located in an annex behind the main building.
Typical prepositions
Pay attention to the difference between 'in' with the dative and accusative. You are 'im Hauptgebäude' (in the main building; location, dative), but you go 'ins Hauptgebäude' (into the main building; direction, accusative).
EXAMPLE
Die Vorlesung findet im Hauptgebäude statt.
The lecture takes place in the main building.

Hauptgebäude vs Hauptsitz
headquarters
'Hauptsitz' and 'Hauptgebäude' can be easy to confuse because both describe something central. But they do not mean the same thing. 'Hauptsitz' describes the central location or central administration of a company, organization, or public authority. So it is about the function of the place. 'Hauptgebäude', on the other hand, means a concrete building that is the most important building in a larger site, for example at a university or hospital. An organization can have its headquarters in a city; on the site, there may also be a main building.
Hauptgebäude
Wegen der Bauarbeiten ist der Eingang zum Hauptgebäude morgen geschlossen.
Because of the construction work, the entrance to the main building will be closed tomorrow.
Hauptsitz
Der Hauptsitz des Vereins ist in Köln, aber es gibt auch Büros in anderen Städten.
The association's headquarters are in Cologne, but there are also offices in other cities.
