ᐅ Interior corner of an older building feels very cold, but the wall itself seems fine. Could it be poorly insulated?

Hello,
here is an older building with a bedroom facing east, sandstone/brick wall.

The room feels very cold, even though it is well heated (new heating system, new floor, 2 new radiators).

I have now taken thermal images of the wall with the windows using a thermal camera.

The problem is the corner of the wall. At a room temperature of 22°C (72°F), it is only 9.5°C (49°F) near the floor and rises to just 11.5°C (53°F) up to the ceiling.

The windows and the wall itself are fine.

Is there any way to improve the corner?

Unfortunately, I can’t provide any qualified input on identifying the cause. This forum is mainly frequented by non-professionals. If you don’t get any helpful responses here, you might want to try asking in a forum for experts.

Get a professional to take a look at it. Not everything can be solved in an online forum.

It is difficult to assess from a distance with the available information.
To help, we would need:
Year of construction, wall structure, close-up photos of the area from both inside and outside, and whether there is actually a draft or if it just feels that way due to the temperature difference.

Generally, I become concerned when there are rainwater downpipes and an unusually cold and possibly damp corner—but it doesn’t necessarily have to be caused by the downpipe. If it is clogged and water penetrates the wall somewhere, that area will also get cold. Without more information, it’s not possible to say more.
