Si vous ne le saviez pas, les joueurs (ou les guildes) pourront construire leurs propres maison dasn Vanguard . voici un post du forum officiel qui en reprend quelques informations (si j'ai beaucoup de courage et de temsp j'essaierai de le traduire )

Plots
Plots are located throughout the world; see below for lists of chunks that contain player housing plots. Plots that are for sale will have a sign in front of a stone marker. Right clicking on the sign will bring up a window that displays some information about the plot and allows you to purchase the plot. After you’ve purchased a plot, you can right click on the stone marker to bring up the plot UI at any time.

If you decide you no longer want a plot, you can abandon that plot by clicking on the abandon plot button. NOTE: You will not get any money back if you abandon the plot.


Construction
To begin construction, go to the construction tab on the UI and select which house to build. For a list of houses available for each continent, see the list below. I will try and post some screen shots of each house and add them here.

Once you begin construction, the stone marker will be replaced with an “under-construction” house model. You can access the construction menu by right clicking on the “under-construction” model. The construction UI displays a list of building materials required to complete construction and the quantity of grade A items required. NOTE: Lower grade items may be used, but a higher quantity will be required. Most of the required items are crafted with the Mineralogist, a type of Artificer, as the primary crafted. Some items are purchased from house vendors who are found in most player housing chunks.

The recipes for the crafted items are either trained from a normal trainer or obtained by completing quests. The quests are available to crafters at level 20, 30 and 40.

Resources for the crafters are obtained from harvesting. You are more likely to get a crafted to help you if you are providing the resources.
Tier 3 materials are required for the One Story homes.
Tier 4 materials are required for the Two Story homes.
Tier 5 materials are required for the Two Story Plus homes. These houses require level 40+ crafters.

Bricks and Cornerstone are made by Mineralogists
Panels and Beams are made by any Artificer (Carpenter or Mineralogist)
Fasteners are made by Blacksmiths
Thatch is made by Outfitters
Kojani Window Coverings are made by Outfitters


Known bugs
Some people have found their plots abandoned after purchase. We’re looking into this issue but you may lose your plot after purchasing it.
