Does anybody know of any layout(s) with stately houses in the scenery? (Low relief or complete buildings)

A complete house might be a bit difficult to build, but low relief should work; a bit of "parkland" with a herd of deer, fancy gateway and gate keepers lodge.

Start with a photo of suitable building scale as required (if possible find a photo with a person or vehicle to aid scaling), make card cut outs with door and window apertures, maybe modify sizes to take available etched brass windows and doors; things like the columns for the porch and decorative mouldings should be available  as white metal/resin castings or 3D prints (York models & Scale link among others), cover the card with Scalescenes brick, or stone etc or a print of your photo  .



This photo has been extended from the original by a bit of copy/paste and some use of the clone tool to fit on a sheet of A4 scaled to approx N gauge (needs a bit more work, you can still see the joins)

Just finished one Mike . I used scalescenes low relief hotel, cut the top off 2nd floor) and used that to extend the sides .
Scaled it down to 3mm ,and set it at the back in the hope it would give the impression of perspective.
Did not think of a deer park ,but thought of a gravel drive ,statues of course ,and maybe even a maze using N gouge hedging.  Still ongoing with the grounds ,so will have to see how it turns out. Had to print out a further sheet to get enough decent pediments ,and here and there used a grey wax pencil.  Could not get the roof on which is a shame ,that's what attracted me to it in the first place.

Buckingham had a small one tucked in a corner. I believe it was built slightly smaller scale to look further away.
