Very nicely done Mr Ripley it all works very nicely. If you want more buildings you should look at the Hornby range in the coming years they make some teriffic ones under the "Skaledale" label they are not cheap but they are very nicely detailed and painted and being OO scale are just about right for BPT layouts. They are also open on the bottom so you can insert LED's or whatever inside them for those lovely night time shots
Happily collecting things all my life...
