Hi Paulo,
If you want Micro layouts, then look no further than http://www.carendt.com - produced by Carl Arendt, this massive website will keep you occupied for months or even years!!! Also pay a visit to Cheshire Railway Modellers (forgotten website) and just to start you off, here's my two micro layouts:
Walmington Pier Tramway - An HO Edwardian British seaside pier 914mm long x 152mm wide.
Routes End 2 - An HO generic modern Light Rail terminus with stabling sidings, 1067mm long x 175mm wide.
Good luck in your searches!
Dave
