This kit is laser cut wood, plenty of strip wood, some corrugated metal, shake shingle siding and a ton of signs.The kit also includes the block and tackle for the lift to the dormer and the material rack for inside the metal clad shed. Construction is our usual "siding on ply" construction, that is you build up an interior "box" and then apply the various sidings to complete the structure. To ease painting, we have separated the window frames from the mullions and have included an adhesive backing on the mullions to make mounting the glazing a glue free breeze! This is a great 4 or 5 evening project.
