Lebisey was almost 100% based on that historical map (drawn by the British from intelligence-gathering patrols). I know there's no church irl but I felt the Germans needed somewhere to coordinate their defence from 
I'm not sure what you mean about the houses though. I used the FH2 statics in positions marked as buildings on the historical map. The bunker in the forest is the "underground petrol storage" on the map, the water towers are there, the AT defence ditch, the burnt out tanks, the roads, the burnt-out houses, the field boundaries, even the orchard trees 
The chateau in the woods is, as far as I know, a fictional addition but it adds a focus to that corner of the map.
The problem isn't the place but the texture. They are very differents from the Manche (maps like Luttich or Purple heart lane) or the Orne.
Around Caen, from the sea to Falaise approximately lots of houses are made with Caen stone, this is very specific for this part of Normandie.

I know you can't made statics only for few maps, this is to many work. But think it for FH3
