Faller, based in the Black Forest in Germany, are probably the worlds foremost manufacturer of building kits. They manufacture in HO Gauge (1:87 scale), N Gauge (1:160), TT scale (1:120) and Z Gauge (1:220). For model buildings, think Faller. With a huge range in different scales of Continental style buildings, any European layout will benefit from the inclusion of Faller kits.
