Please can you translate this into English?
"Einerseits gedrungen und plastisch wie die alten Fläscher
Herrschaftshäuser, verdankt er seine fünfeckige Grundform der
spitzwinkligen Parzelle, bzw. dem daraus abzuleitenden, korsettartigen
Baufenster, dem im Süden ein kleiner Garten vorgelagert ist." (From a
description of a building completed in 2001)

Dear leander1,

Here is the translation you requested. Please note the annotations I
inserted for the terms "Fläsch" and "Grundform". Also, the term
"Baufenster" refers to a complex planning regulatory definition of
what part and area of a lot may be covered by a building.

"On the one hand compact and plastic like the old manor-houses of
Fläsch [obviously referring to a town in the Canton of Graubünden,
Switzerland], it receives its pentagonal basic shape [or: ground plan;
the exact context of 'Grundform' is not well-defined by this short
paragraph] from the acute-angled lot, respectively from the resulting
corset-like share of the site where erecting a building was allowed,
with a small preliminary garden."

Hope this is what you needed!
Best regards,
