Hmm, the doors frames etc being raised would give the buildings a bit more definition. That said, there are quite a few architecture styles that have the frames fluch with the sides. Is that the case with these? Not my area of knowledge.
Not really. Actually, apart form the shape of the building fronts, there's not much Dutch (or Belgian I reckon) about these buildings to begin with.
But then again, I yet have to see an accurate, or even good approximation of a real Dutch style house (if indeed there is such a thing. If there is though, it sure as heck won't have shuttered windows or exposed beamwork...)
I am tempted to buy from them though, but only the residential urban buildings, which can pass for Victorian style housing, but can also be found in Dutch urban areas...
