"Windows are cheaper or at least price-neutral, and all houses with a lot of glass are a sign that the builder wants to save money"
...and all houses with a lot of glass are a sign that the builder wants to save money"...
Interestingly, the sales representative from Helma told me the opposite: "Windows are cheaper/or price-neutral and all houses with a lot of glass are a sign that the builder wants to save money." However, it must be said that at Helma - regardless of the building structure and complexity - the price per square meter always remains the same. That seemed a bit strange to me, at least that's what their sales program shows. I am still waiting for a concrete offer.
