I am going to answer the question that the OP has raised "
So You Think Playmobile Is Toylike And Not Worthy Of A Place On Your Line?
Yes
Ian, I thought that some of the adaptions that I and others have done might have made you think a bit differently. Never mind. We all have our Rule 1.
Now for my final piece some of the changes that I have made to PM Buildings. The first one is not so much of a change, just to use pretty well as is because it is a rather nice Halt Station. I use it for my Sternhaus Station. As you can see from the picture below the prototype has limited facilities. I have given the residents a nice new shiny roof to wait for Trains. Though I think that on a Snowy Day the Garden Shed might have been more appreciated by the residents of Sternhaus.

Below is the PM Model Cat 4382:-
This is how I have used it on my line, note the Clock set forever to Pub o Clock:-
Next we come to Cat 5301 The Grand Mansion, I lucked out at a Bootsale with this one going for a very reasonable £10-15 quid I think. I had the vague idea that it would fit in somewhere in my old Garden at Hemel. However it was just too big so languished for a while till I had the lightbulb moment and it became 2 Station Buildings and a Hotel/Bar. I had a very inconveniently placed Brick Support Wall and just wrapped part of the structure around it.
They have all found a new place on my current line.
The Wrap Around one as a Hotel at the end of my Alexisbad Station, it also doubles as a Wagon Load Store. Plus it disguises nicely the exit from the scenic Alexisbad Station to the non scenic bit of the Shed that has my Workshop and Carriage Siding. The inevitable East German Trabant Executive Saloon awaits it's Driver.
As you can see the other side is not so pretty beyond the PM Structure, but as it is impossible to see this no problem.
Here is how the Hotel has been used as an add on to my Silberhutte Station:-
And my old Gernrode Station is emerging as a small halt called Strasberg. Still work in process as the levitated Building shows.
Finally for inspiration just a few more Buildings that I think are of Great use for the builder that wishes to capture that nice old European feel. I have not used any of these, but if I had space I would not hesitate to hunt them out.
