Skyscraper aims to be a fully featured 3D virtual building simulator. Skyscraper is an open source program simulating a 138-story skyscraper. Skyscraper represents an open-source program that will simulate entire buildings in first-person 3D. It aims to be a fully-featured, modular, 3D realtime building simulation engine, and will eventually include game support.

Skyscraper aims to be a fully-featured, modular, 3D realtime building simulator, powered by the Scalable Building Simulator (SBS) engine. The main feature SBS provides is a very robust elevator simulator, but also simulates general building features such as walls, floors, stairs, shaftwork and more. Many more things are planned, including gaming support (single and network multiplayer), and a graphical building designer. Skyscraper is written in C++ and uses the Crystal Space 1.4 graphics engine, the wxWidgets GUI library, and is multiplatform. The current versions aim for a future 2.0 release.
