ᐅ Possible Thermal Bridges at Wall Corners in New Construction

Good evening,
Our new build is mostly complete, and the interior work is in full progress. The underfloor heating has been running for about 5 weeks.
We built with Wienerberger T10 36.5 without additional external wall insulation. Three of the four walls are below ground level, as our site is on a slope.
Where the brick wall meets the concrete wall, the internal temperature at the joint and corner is about 10°C (50°F) with an outside temperature of 1°C (34°F).
The other walls are around 15°C (59°F).
We took our first measurements today and will continue to monitor this daily.
What do you think—should we consider insulating the exterior facade after all?
In my view, this would clearly be a planning error, wouldn’t it?

Or are the house corners made of reinforced concrete?

The exterior plaster will be applied next year. From your perspective, is that an issue?
Our architect says it’s fine, but he usually says that... I’m a bit uncertain.

We have temporarily plastered the corner on the outside. Additionally, the concrete wall inside the garage has been insulated.
Of course, we didn’t have really freezing temperatures, but since then the corner has been drying well.
However, we now feel that the garage roof might not be completely watertight. For this reason, we opened a section of the upper insulation. It was damp underneath.
Now we are puzzled... It probably can’t be condensation since, as mentioned, the outside temperature hasn't been that cold.
What do you think—could the roof not be properly sealed?
