Bachmann 45191 House Under Construction Plasticville USA Kit HO ScaleThis is a snap-together plastic kit. Plasticville® pieces add character and dimension to your HO scale layout. Many buildings and accessories have been added to the Plasticville® line throughout its history, and many are still produced from their original molds. As a fun challenge to collectors (you can even join the Plasticville Collectors Association), you can collect hundreds of product, color, and packaging variations that have occurred over the years. Whether you're new in town or an established civic leader, Bachmann builds Plasticville® U.S.A. for you. City growth is limited only by your imagination!
