This model comes in several pieces including: building body, roof, roof supports and chimney. Due to the size of the building the 00 version have the building split in half and has an extra block of brick texture for the roof. 
 
The building is scaled in both 00 gauge and N gauge. For those modelling in TT:120 the N gauge model can be scaled by 125% and those modelling in 3mm can scale the 00 gauge model by 75%.
