Each planet type has a different number of building slots. These slots come in three varieties, resource harvesters, city buildings and space stations.
Some buildings, such as the Residential Community can be built several times on a single planet with cumulative effects. These buildings are recorded in the table below with a 'yes' in the MPP (Multiple-Per-Planet) column.
Some buildings have a system-wide effect. The Commercial Dock provides transport ships for moving and trading resources. Some of these buildings have a cumulative effect when more than one is built in the same system. For others, only the highest level building in the system has any effect. These two scenarios are recorded as 'cumulative' and 'highest level' respectively in the MPS (Multiple-Per-System) column below.
The Intergalactic Relations Center is a special case. Only one may be built anywhere.
There is one type of resource harvester for each resource. The number and location of these buildings are fixed by the planet's type.

Space stations can be divided into two categories. Regular space stations require only a single building slot. Large space stations require all building slots on a particular planet.
