The first permanent settlement on [[Neutanoa]] was founded on 16 February 1991 as a sealed construction camp supplied from Aconcagua and Earth orbit. Workshops at [[Siedlung Neutanoa]] tested power systems under planetary conditions before larger residential construction began, showing that an off-world community could remain occupied between supply missions. The [[Planetarisches Bauamt I]] was created on 27 September 1993 to standardize sealed buildings and their utility connections. It introduced common pressure doors and power couplings for settlements and spacecraft. A permanent mining base opened on Eisenwelt on 4 April 1994 and began supplying [[Ferrum nigrum|ferrum nigrum]]. The metal reduced the mass required for pressure frames and external armor, addressing the structural shortage that had blocked the first city-ship design.

Construction machinery reached [[Himmelswerft Schwarzhafen]] on 6 January 1995, allowing hulls to be assembled in orbit from Patagonian modules and off-world structural metal. [[Octavio Lascano Biedma]] supervised the transfer before [[Ramiro Zubizarreta Oribe]] assumed control of the branch later that year. The Himmelswerftdirektion authorized the first complete city-ship hull on 12 December 1996. A Patagonian resistance cell destroyed two habitation sections awaiting transport from Puerto Deseado on 3 August 1997, after which pressure testing moved to Schwarzhafen while replacement modules were built. [[Grüngürtel I]] began operation on Grünmond on 8 May 1998 and replaced stored food shipments with a complete local growing cycle. Its agricultural design entered the unfinished city-ship, but early water-recycling equipment accumulated dissolved metal from the pressure system. A revised filter plant began continuous testing aboard the hull in February 2000.
