House Portal

A House Portal is any furniture-like item that can be placed in a player house or guild hall. In a house you own this as simple as getting a portal, traveling to another house your character owns, and placing it as you would with furniture. In order to get a portal you must own a Prestige house.
 * You must own the house you want to place a house portal in or have the correct level of access set by the owner (even other charcaters on your account. The same is true of their placement in guild halls.

The Benefit of Getting a Portal
Any Prestige Housing you get via the Marketplace using Station Cash, those that come from special offers (typically pre-orders of game expansions as well as, special events and other sources can be used as a link between one or more houses or a guild hall. In effect, they allow you to travel effortlessly from one place to the next and (if you have housing in multiple cities), you can even use them as a means of fast travel from one city to the next.

Getting and Placing a House Portal
No matter where you are in the world, all you need to do to get a portal (after you own a prestige house) is to open the Housing & Leaderboards window and find the house portal you'd like to get in the list under the My Houses tab. The quickest (and generally easiest) way to open the Housing & Leaderboards is to press C and open the character sheet and click on the Housing side-tab.

After doing so the rest is as easy as follows:
 * 1) Go to the house or guild hall you want to place it in.
 * 2) Press B to open your bags
 * 3) Locate the portal in your inventory (the icon is that of a door, shown in the image here)
 * 4) Right click on the portal in your inventory
 * 5) Select the Place option. Doing so will make it an object (like furniture)
 * 6) Use your mouse to move it around and when you like the location, press the left mouse button to "release" (place) it in that spot.

Moving and Resizing
You can resize these like normal furniture, but because they have an actual click-on to zone (into the house they represent) function, you'll need to the use the manual decorating options. This means you need to be in the process of placing it in order to make it smaller, larger, or to lift in up pr down in the house. To do so, right click on a placed portal and choose Move from the options.
 * Holding down the CTRL key and using the scroll wheel on a mouse will lift it up and down (in the air)
 * Holding down the SHIFT key and using the scroll wheel on a mouse will make it smaller or larger.

Tips and Tricks

 * Many players use these portals as a way to "link" multiple houses, by placing portals from each prestige house they own in a single location. The house you place it in does not need to be a prestige house, but can just as easily be a Standard house
 * Many player use the portal-linked houses described above as a "portal hub" by including other house items that allow for travel in one location, like a guild hall door.
 * Because they are attractive, many players use these almost as one would a painting, by placing a building block like a wall to frame it.
 * In situations where it doesn't suit the decor, the house portals are easily moved far above the visible ceiling or floor in most houses.
