Blueprints for spacecraft and buildings are created using the Shores of Hazeron Designer. The designer is a free form 3D surface modeler, accessible in-game and out-of-game. All buildings and spacecraft in Hazeron are designed by players.

Architects publish their blueprints at the in-game Blueprint Exchange so other players can get them. Publishing terms, set by the architect, dictate who can access their published blueprints. The exchange contains 1,617 blueprints. This page only shows blueprints with terms accessible to everyone, regardless of empire, listing 120 of 259 spacecraft blueprints and 1,129 of 1,358 building blueprints.

Final blueprints are ready for use in the game. They are optimized from the original drawing, through a process called finalizing. Final spacecraft show MinQ, the minimum quality of materials needed to manufacture a spacecraft using the blueprint.

An Assembly blueprint may be at any stage of completion. It could be ready for finalizing, as with the Atlantis assembly. It could be a set of useful geometry, such as furniture and consoles. An assembly is simply a saved copy of a blueprint, with nothing left out.

Prices are in cronodollars ¢, the money of the game. Cronos are not related to real money. Spacecraft and building blueprints do not cost real money.
