Headquarters
From OpenTTD
In OpenTTD, the headquarters or HQ is the building where all administration of your business is carried out. You can click on a headquarters to open the Company Window, to change any details for your company.
The headquarters, like your company, will grow larger and upward to show your success as a company. Overall there are five stages for the headquarters, starting off as a small building no larger than a house, and finishing as a very tall skyscraper sized building.

The HQ also accepts passengers and mail delivered to it as well as providing a limited amount of passengers and mail itself.
As the HQ shows your success, it is common for players to build them as centerpieces of the transport empire, usually atop a large, artificial mountain, or on an island in the sea. It is common to see millions spent on such large areas.
There are various different NewGRFs available if you don't like your HQ design, or it being dwarfed by other buildings in the town!
