Three things to know before you buy

  • 1
    You'll need a level base. Gravel, slab or deck blocks — sized 12′1″ × 10′1¼″. Not included.
  • 2
    Roof boards are included; the top layer isn't. The 4° slope needs metal, rolled or PVC — shingles won't shed water at that pitch.
  • 3
    It arrives as sanded, kiln-dried, untreated spruce. Bare wood has no weather protection, so stain or paint it within the first few weeks — you pick the color.

In the box — and not

One pallet. Almost everything.

Every wood part is pre-cut and numbered. Three things are deliberately left to you, because climate and taste vary too much to ship one answer.

  • Roof boards, floor kit & joistsT&G spruce floor on pressure-treated joists
  • French double door, lock & keys52″ × 6′2″ with dual-pane glass

You'll add — and roughly what it costs

  • Foundation DIY $250–700 · pro slab $1,200–2,500Level, well-drained, 12′1″ × 10′1¼″. Built before the pallet arrives — size it in the foundation calculator.
  • Roofing material $200–600The 4° slope needs metal, rolled or PVC — shingles won't shed water at that pitch.
  • Stain or paint $100–3001–2 gallons outside, about a gallon inside, and a quart for trims and floors. Try the colors on the 3D model before you buy a can.

From our warehouse to your curb

Delivery, then a weekend.

Step 1

Order — on your schedule

Buy now, build later: tell us when you want delivery and we hold the kit. Free shipping in the lower 48.

Step 2

Arrives in 1–3 weeks

One flat-packed pallet, about 2,260 lbs, every board pre-cut and numbered.

Step 3

Curbside drop-off

The dispatcher calls to agree a window. The pallet is too big for a liftgate, so it comes off by hand — plan on two people for about an hour. Driver-assisted unloading and expedited delivery can be added for a fee; ask us for a quote when you order.

Step 4

Build it — 8–20 hrs, 2 adults

Check the pallet against the packing list in the first 30 days — anything damaged or missing ships free. Boards interlock tongue-and-groove; no framing skills needed. Manual, blueprint and video library included. Prefer not to? A local handyman can build it — ask us and we'll recommend someone if we cover your area.

Tight street, steep drive, or an island address? Call before ordering — we'll check the route with the carrier so there are no surprises on the day.

Common questions

Frequently asked questions.

At 117 sq ft this model sits under the 120 sq ft threshold most US counties use, so a permit usually isn’t required. Rules vary by county and HOA, so one call to your local building department settles it. Every kit includes a blueprint you can hand them if plans are asked for.
A level, well-drained base sized 12′1″ × 10′1¼″, flat within ¼″. A compacted gravel pad, deck blocks or a timber frame all work; a concrete slab is the premium route but is not required. Most owners do it in an afternoon for $250–$700. The foundation calculator gives you the shopping list and cut list.
The 4° slope needs metal, rolled or PVC — shingles won’t shed water at that pitch. Budget $200–600 for 166 sq ft of roof area. Roof boards themselves are included in the kit.
Most owners finish in 8–20 hrs, 2 adults with basic tools — hammer, drill, level, ladder. The wall boards interlock tongue-and-groove, so no framing skills are needed. Manual, blueprint and video library are included, and the support line answers mid-build questions. If you would rather not build it yourself, a local handyman can — we can recommend services in some areas, so ask before you order.
Yes. Insulate the roof above the T&G boards under your roofing layer, and the floor between the joists. The walls are solid 1⅜″ double T&G spruce with good thermal mass; pair with a mini-split for full climate control.
Yes — most office and studio builds do. Conduit surface-mounts neatly along the solid wood walls with clips, so no in-wall channels are needed and the wiring stays inspectable. Plan the trench or overhead run before the build. A shed under 120 sq ft rarely needs a building permit, but the electrical work usually does — ask your city whether it wants a permit and an inspection.
Free curbside freight in the lower 48. One flat-packed pallet of about 2,260 lbs arrives 1–3 weeks after ordering; the dispatcher calls first to agree a window. The pallet is too big for a liftgate, so it comes off by hand, board by board — plan on two people for about an hour. Driver-assisted unloading and expedited delivery can be added for a fee; ask us for a quote when you order.
The two opening side windows install toward the front or the back of the side walls — you decide during assembly, at no cost. The French door and the two tall front windows are engineered into the front wall panel and cannot move. An add-on double window ($495) can go into either side wall.
Call (800) 590-2508 ext. 1 within 30 days of delivery and the replacement part ships free within 10 business days. The 1-year limited warranty covers manufacturing and workmanship defects.

Second-guessing the size?

The two nearest neighbors.

Most people who return to this page were deciding between these three. Same build, same wood — only the footprint changes.

One size down Aspen 12 × 10 103 sq ft 14 sq ft smaller — still fits a desk and a chair, tighter for a meeting corner. $7,495
You're looking at California 13 × 11 117 sq ft Desk, shelving and a reading chair, with the door and four windows placed where you want them. $8,895
One size up Optima 12 × 12 136 sq ft 19 sq ft more — room for a second desk or a proper sofa. Note: over the 120 sq ft permit line in most counties. $9,295

Still torn? Call (800) 590-2508 — tell us the room you want and we'll tell you which one fits it.

Environmental commitment

25 trees planted with every purchase.

Every order plants 25 trees through the Cauvery Calling movement. The shed itself is slow-grown Norway spruce from our own family mill, sustainably harvested and milled to order.
