Specifications

2×4 Douglas fir framing, 16″ on center in the floor and 24″ on center in the walls and trusses, with double top plates. 3/4-inch CDX plywood floors and 1/2-inch CDX roof plywood. Douglas fir T1-11 siding. A moisture barrier in the roof, floor and walls using synthetic roof paper and Tyvek. A 30-year black architectural composition roof. Pressure-treated 4×4 skids on 4-inch concrete leveling blocks. And a single out-swing door in 36, 42 or 48 inches with a lockable handle and black colonial hinges. Delivery, installation on a prepped lot, and a limited 5-year workmanship warranty are all included.

Site prep is the customer’s responsibility, but the specs are straightforward. For gravel: 4 inches of 5/8-minus crushed rock, compacted well, spread a foot past the perimeter of the building on all sides. That extra foot handles drainage and keeps weeds down.

For concrete: pour the slab 4 inches above grade and an inch shorter than the building in both directions, so the walls tie straight to the concrete and the siding drapes over the edge and seals moisture out of the floor. The shop doesn’t do site prep in-house but has landscapers it refers people to, and most customers end up using one of them.

Not much. Most sections are panelized at the shop and carried in by hand, so 3 feet of width and 10 feet of height is usually enough, plus room to turn the corners of the house. Anyone with a tight gate should send a photo before signing anything.

One to two days for a building with a bare-bones interior. Twelve to fourteen business days for a fully finished one, because the schedule has to leave room for the electrician and the inspections.

Yes. Douglas fir T1-11 is standard, and past builds have gone out with Hardie lap siding at a 7-inch reveal in a cedarmill texture. Roofs can be extended two feet past standard for more overhang, and CertainTeed shingles have been used on custom orders. Anything along these lines gets priced with the quote.

Standard walls are 7 feet 4½ inches, and they can go taller or shorter. A loft is the best value of any add-on, since it turns dead roof space into real storage. On buildings with side walls over 12 feet a loft does double duty as the spreader that keeps the walls from pushing outward, and gables over 12 feet need manufactured trusses.

Yes, in any brand and color from a local paint store. The customer buys the paint and the shop applies it before installation for an extra charge. Walls get painted indoors at the shop, out of the weather, which is why the color has to be picked early. Anyone planning to paint it themselves can ask for primed whitewood siding instead.

Workmanship. It doesn’t cover settling, which comes back to the foundation, and it doesn’t cover anything with its own manufacturer warranty, like the roofing shingles.
