6m Wide Montana and SiP Barns

The Montana Barn’s distinctive look comes from the collar tie trusses which are located at 1.2m centers along the eave beams. The most popular size in this design is the three bay, six meter wide barn. This gives an 82m2 ground floor area and a 55m2 upstairs, a total of 137m2.

The 6m wide SiP frame offers a modern ceiling line, replacing the Montana’s collar tie trusses with large dimension rafters with purlins between. The SiP frame was designed specifically for structural insulated panels (SiPs) but the modern design also appeals to those who prefer to build conventionally.

The 4.8m Montana version has a 1.2m knee wall height and a 2.1m clearance below the collar tie on the first floor. This design has a 40 degree pitch which means that about 75% of the floor space offers standing room for someone 1.8m tall. This barn suites large gable end windows to bring in light and the use of skylights to bring in additional light if needed. This frame suites one or two loft bedrooms or can have a lean-to veranda added to create a cozy 2 or 3 bedroom home.

For areas where secondary dwellings need to be 70 m2 or less, the bay width can be reduced to 3.9m modules. This is ideal for a secondary dwelling or garage with sleeping accommodation above. For garage spaces we typically add horizontal girts which allow the cladding to be direct fixed to the frame while wall framing and insulation can be added upstairs.
