Here is a very interesting single track locomotive shed with exposed steel truss construction with red brick infill featuring a barrel roof. Experience building these kits is suggested, try building a few of the Archistories buildings before this one. The steel truss framework is made of very fine cardstock comprising four pieces: one per side. Very little room for error with this kit: gluing and assembling has to be quick. And re-positioning the fine lattice truss is not possible (tears easily). For alignment I lined up the bottom of each side with the bottom of the building, I then allowed the lattice framework to naturally fall into place before applying light pressure for gluing. Maybe as an alternative try placing the steel truss on the building and then apply tiny drops of glue in several discreet places. The whole range of z locomotives are easily serviced in this shed which features large windows and hinged doors.
