G-Scale Building Kits

Bring more detail and personality to your railway with G-scale building kits designed to create realistic towns, stations, industrial areas, and trackside scenes. The selection includes PIKO and POLA structures such as locomotive sheds, railway stations, warehouses, factories, storage buildings, platforms, homes, and other distinctive additions for a G-scale layout.

Only Trains offers a range of structures for different levels of involvement, from pre-built buildings that can quickly become part of your layout to elaborate building kits for hobbyists who enjoy assembling and detailing their own structures. Whether you want a convenient addition or a more hands-on project, you can choose buildings that match the amount of time and customization you want to put into your railway.

Whether you want to create a busy rail yard, a small community, or an industrial district, these kits give you plenty of options for developing a more complete setting around your trains. You can also combine structures and accessories to create scenes that fit the size and theme of your layout. Browse our G-scale building kits to find structures that add visual interest, depth, and a stronger sense of place to your railway.
