Notes
The Orbital Office is a cheap, flexible space station design intended to provide space for administrative and other support amenities for orbital drydocks. [2] The station core consists of a small hangar bay which can handle Work Bees or small shuttles, an arboretum/recreation area, and several large bulk storage tanks. Various booms can be attached below the arboretum; modules of various sizes can be attached to these to provide living and working space. 
A typical module might provide transportation links via a transporter and one or more docking points for small shuttles such as travel pods. Others provide power systems, office space, recreation areas, or other facilities.
