Three things to know before you buy

  • 1
    You'll need a level base. Gravel, slab or deck blocks — sized 11′10″ × 9′1½″. Not included.
  • 2
    Roof boards are included; the top layer isn't. The 3:12 pitch takes shingles, metal or PVC — match the house.*
  • 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. See our Paint and Stain Guide.

* Between 2:12 and 4:12 lay shingles over two layers of felt or an ice-and-water shield. See our roofing guide.

In the box — and not

One pallet. Almost everything.

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

Included in the kit

  • Double tongue-&-groove wall panelsSustainably harvested Norway spruce, untreated
  • Roof boards, floor kit & joistsT&G spruce floor on pressure-treated joists
  • Double door, lock & keys4′3″ × 6′
  • 2 double-pane windowsFront 2′6½″ × 3′4½″ + side double 4′7″ × 3′4½″, tilt & turn
  • All hardware, manual & blueprintPlus the full video library — build in 1–2 days

You'll add — and roughly what it costs

  • Foundation DIY $250–700 · pro slab $1,200–2,500Level, well-drained, 11′10″ × 9′1½″. Built before the pallet arrives — size it in the foundation calculator.
  • Roofing material $240–960The 3:12 pitch takes shingles, metal or PVC — match the house.*
  • 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. Which finish for your climate: Paint and Stain Guide.

* Between 2:12 and 4:12 lay shingles over two layers of felt or an ice-and-water shield. See our roofing guide.

Typical owner-built total: the kit price plus foundation, roofing and stain. Hiring out the base and the build adds roughly $2,700–$5,500.

From our warehouse to your curb

Your shed, step by step.

Step 1

Order — on your schedule

Order now, receive it later: tell us when you want delivery and we'll hold the kit until then. Free shipping to the lower 48.

Step 2

Arrives in 1–3 weeks

One flat-packed pallet, about 1,750 lbs, every board pre-cut to size.

Step 3

Curbside delivery

The carrier will arrange a delivery window with you. The pallet is too large for a liftgate, so for standard delivery, plan to have two people available to unload it by hand. It usually takes about an hour. Driver-assisted unloading and expedited delivery are available for an additional fee.

Step 4

Build it — 1–2 days

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.

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

Fast

“Fast. Good communication. Exactly what we expected. Well priced.”

Excellent quality product

“Excellent quality product, from the wood to the doors. It's never easy to take on a major project like this as a husband and wife team, but with the SolidBuildWood staff being incredibly responsive to a couple of questions we had about the directions, we ended up with a beautiful 'guest house'/formally a shed. We were able to get it done in a 3 weekends with one other guy, and we did hire local roofers. In 3 short months we created a beautiful place for my 92-year-old father in law to sleep. This was far superior to leaving him in a facility. It cost us 1.5 months of what the facilities charge and is far warmer, more personable and beautiful and best of all - we are right there for him!”

Common questions

Frequently asked questions.

At 103 sq ft, Aspen may not require a building permit in some locations, but requirements vary. Check with your local building department before you build. Every kit includes a blueprint you can provide if requested.
A level, well-drained base sized 11′10″ × 9′1½″, flat within ¼″. A compacted gravel pad, deck blocks or a lumber frame all work; a concrete slab is the premium route but is not required. A simple DIY base usually takes an afternoon and costs around $250–$700 in materials. The foundation calculator gives you the shopping list and cut list.
The 3:12 pitch takes shingles, metal or PVC — match the house. Budget $240–960 for 133 sq ft of roof area. Roof boards themselves are included in the kit. Between 2:12 and 4:12 lay shingles over two layers of felt or an ice-and-water shield. See our roofing guide.
Plan on about 1–2 days 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 our support line answers mid-build questions. A local handyman or an assembler would be one to hire.
Yes. The roof can be insulated above the tongue-and-groove boards, under the roofing layer, and the floor between the joists. The solid-wood walls are designed to expand and contract naturally, so they shouldn't be insulated like conventional framed walls. Depending on your climate, add a heater or mini-split for year-round use.
Yes. Power and lighting can be added using surface-mounted conduit, keeping the solid-wood walls intact and the wiring accessible. Plan the electrical route before the build, and use a licensed electrician for the installation. Electrical permit requirements vary by location, so check with your local building department.
Free curbside freight to the lower 48. One flat-packed pallet of about 1,750 lbs arrives 1–3 weeks after ordering. The carrier will arrange a delivery window with you. The pallet is too large for a liftgate, so for standard delivery, plan to have two people available to unload it by hand. It usually takes about an hour. Driver-assisted unloading and expedited delivery are available for an additional fee.
Aspen includes one opening front window and one double opening side window. The double window can be installed on either side wall during assembly. The French doors and front window can be swapped places during assembly as well.
Let us know within 30 days of delivery and we'll take care of it. Missing or damaged parts are replaced free of charge. Reach out or call 1-800-590-2508 ext. 1 and we'll help get it sorted. The 1-year limited warranty covers manufacturing and workmanship defects.
