HO Scale Building Kits & Model Railroad Structures

Create towns, industries, businesses and trackside scenes with HO Scale Building Kits from MegaHobby. Structures help transform a model railroad from track on a surface into a recognizable miniature world, giving trains destinations to serve and providing visual context throughout the layout.

Building kits also give railroaders a modeling project separate from locomotives and rolling stock. Assembly, painting, signs, weathering and interior or exterior details can all be used to give a structure its own character.

Build HO Scale Towns & Industries

Structures can establish the purpose of a scene, whether you're developing an industrial district, commercial street, rural area or railroad facility. Multiple buildings can be arranged together to create a convincing community around the tracks.

For ready-made structure options, browse Built and Ready Buildings.

Add Figures & Vehicles

Bring completed structures to life with HO Scale Figures and HO Scale Vehicles. People, cars and trucks help establish how a building is being used and can make even a small scene feel more active.

Landscape Around HO Buildings

Connect structures with the surrounding environment using HO Scale Scenery and Landscaping Materials. Roads, terrain and vegetation can help blend a structure naturally into the layout.

Paint & Weather Model Railroad Structures

Visit the Paint Store for colors and primers used on brick, wood, concrete, metal and other modeled surfaces. Browse Weathering Products for fading, grime, rust, staining and age.

Careful weathering can help a structure reflect its purpose and environment, from a maintained storefront to a heavily used industrial building.

Customize HO Scale Buildings

Builders modifying structures or creating additional details can explore Scratch Building for styrene, structural shapes, siding, roofing and other fabrication materials.

Browse Tools & Supplies for knives, cutting tools, adhesives, sanding products and other equipment used during structure construction.

MegaHobby's HO Scale Building Kits give model railroaders the structures needed to turn open layout space into detailed towns, industries and trackside environments.
