Oh, are those holes almost the size of the paving stones? I was thinking more of drill holes the size of knots in wood. Pretty much. Zoom in closely, and you can see the size of the holes behind it.
The guy who came with the apparatus used to blow in the cellulose insulation was nicknamed "Flocki" by the construction team.

Retrofitting air cavities in cavity walls from the 1980s/sarcasm mode on
Noticeable air cavities in cavity walls were only common in buildings constructed roughly between 1900 and the early 1960s.
The cavity thickness ranged between 2cm and a maximum of 15cm (1 inch and 6 inches), but usually air gaps of 6–8cm (2.5–3 inches) were left. Only in older buildings, especially villas from around 1900, did air cavities sometimes measure between 12 and 15cm (5–6 inches).
From the 1960s onward, facing bricks were mostly installed without an air cavity, using mortar joints in a “sharp mix” as a moisture barrier directly against the load-bearing wall. However, since everything was allowed until November 1, 1977, there are exceptions and special constructions within this timeframe. For example, my older building from 1959 has, according to the building permit, a 4cm (1.5 inches) air cavity between the load-bearing wall and the facing masonry. But during the inspection for the planned blown-in insulation, we found that 2cm (0.75 inches) styrofoam boards were already glued over the entire exterior wall.
From 1977/78 onwards, brick facades with insulation and sometimes with ventilated cavities were installed again—but no blown-in insulation is added, since insulation is already present.

Yes, that is really a pity. We thought for a long time about whether we still wanted the window. Having an unobstructed view would, of course, be great, but it’s unlikely to find a lot where you get such a view. So you have to live with the conditions...Here in our rather plain northern region, this house is a real eye-catcher, and that’s the reason for choosing this window—to create a holiday atmosphere.
