ᐅ Construction of a ground-level, covered terrace directly attached to the house

Hello, we would like to build a ground-level terrace on the east side. It should be paved with travertine stone on a layer of crushed stone. For moisture protection, it is well known that a 30cm (12 inches) splash guard should be maintained. I am aware of this, but in this case, a ground-level terrace simply wouldn’t be possible.

My first thought was to use frost protection gravel and crushed stone right up to the facade and protect it with a drainage membrane. However, I’m concerned that this might not be good for the house in the long run due to moisture (even though the terrace is actually protected from rain by a pergola).

Attached is a picture for illustration.

Now my question is whether it would be possible to simply build a concrete base to connect the terrace to the building. That is, to pour a concrete base about 10cm (4 inches) wide and 60cm (24 inches) high between the house facade (timber frame construction) and the terrace. In this case, moisture shouldn’t be an issue anymore, right? Alternatively, drainage channels could be installed along the house, but these would also need to sit directly on crushed stone or concrete against the building.

Of course, this might not be fully compliant with standards, but it should work, or am I missing something?

Thank you very much in advance!

The splash guard is omitted in the terrace area. Since it will be covered, only a small amount of rain and therefore little moisture will reach that area anyway. According to standards, a drainage channel is required, but if you do not have a risk of standing water, you can also leave it out.

Our terrace is also covered and has a simple slope of 1% away from the house. And yes, if bad weather happens to come from the south, the exterior of the house can sometimes get a bit wet.

This is installed to keep the facade from getting dirty. If the area is paved, this issue usually doesn't arise. Plus, the facade should be able to withstand rain.

Unnecessary nonsense...

Did you attach the lamp above with steel screws? It's already starting to rust. It should be fixed with stainless steel screws.

Without concrete, the gravel would basically be separated from the house facade only by a dimpled membrane – I’m concerned that over time, moisture might still get to the house from below or above.
