While buying this plan for cash requires having the Nagrand Outpost or being Level 100, as it indicates on the tooltip displayed here, using Guide détaillé sur la construction d'avant-poste only requires having the manual.

You can thus upgrade your Large building just by completing the introductory Talador quest line for establishing your Artillery Tower or Arcane Sanctum. You can get starting quest at level 94, Des nouvelles de Talador. Alternatively, start with the quest available at the board in your garrison, La voie stratégique. Then follow the special chain for your chosen building until the construction guide is awarded.

Your special ability will become active before the end of the quest line. For the Arcane Sanctum quests you have to do keep going with Le pied de la forteresse through to Une bonne raison de se réjouir, unlocking Magistrice Serena / Magistère Krelas as a follower.

For the Artillery Tower it is Chez les Gordunni through to La seule manière de voyager, unlocking Miall / Morketh Hurlame as a follower.

Once you have Guide détaillé sur la construction d'avant-poste, head to Stormshield and find Kinkade Jakobs on the in-progress building next to the flight point to exchange it for the blueprint.
