Just moved into a place and one of the bedrooms (corner room, extends beyond second story) is easily 5 degrees colder than the rest of the house. Heating is forced air.
I have to use a space heater for supplemental heat in that room.
What kind of heat? Are the walls insulated? Is the door kept open for return air flow? What's below and above? Are the windows closed and well sealed?
Forced air.
Don't know about the insulation situation.
Doesn't matter whether door is open or closed.
Below is a crawl space (insulated rafters), nothing above.
Windows closed obviously, but can feel that it's clearly colder near the window. But it's no different than other windows in the rest of the house since they're all the same windows (double hung, double pane).
There are many factors that can contribute to this condition-
And without going into a long drawn out diatribe, I strongly suggest getting an energy audit for the home. The results may surprise you; and you may even find a direct correlation to the condition of that one room.

We have a few rooms colder than the rest intentionally because they are rarely used guest rooms, so the furnace vents are closed and doors are closed. In your case, it could be a clogged duct (mouse nest) or an undersized duct. The most likely cause, though, is the room is far from the furnace, a long duct run, and the room with the thermostat in it heats up a lot faster. You can supplement with a vent fan device, rather than a space heater. When the furnace is on it will pull more into that room.
Yes. eta: Not that it is correct to have but that it occurs often enough that it can be considered "normal" to have it all the same.
It will likely be warmer than the rest in the summer as well.
There is a tree shading it so summertime isn't much worse. I'd say my computer running in that room adds more heat than sunlight.

Some newer thermostats have a "Circulate" fan setting. This will run the fan 20-35% of the time minus the time when the heat or AC is running. This fan setting is apparently supposed to help with hot and cold spots. Note that this setting isn't recommended if you have a zoned system.
