Custom Builder
Design exactly what you want
Before you buy a shed, ask what it's made of.
Every shed I build includes upgraded materials most builders charge extra for — or don't even offer. All 23 sizes, all options.
What's included when I build your shed
Before you add a single option, here's what's already in the price. Ask the other guy for his list.
50-Year Exterior Panels
Engineered LP SmartSide with waxes, resins, and zinc borate. Resists moisture, rot, and termites for decades.
↳ Competitors use OSB or T1-11 that starts rotting in 3–5 years
3/4" Moisture-Resistant Flooring
Advantech/DryMax resin-infused subfloor. Won't swell, buckle, or delaminate.
↳ Kit sheds use 1/2" plywood that warps in one season
Treated Floor Joists, 16" O.C.
30-year ground contact rated lumber, sized to the span, elevated on TuffBlock footings for airflow.
↳ Prefabs use 2×4s at 24" spacing, or steel that rusts
PVC Trim — Maintenance Free
25-year rated. Won't warp, cup, split, or rot. Never needs repainting.
↳ Wood trim needs repainting every 3–5 years
Built On-Site, In Your Backyard
Constructed from scratch, right where you want it. Tight gate, narrow side yard, back corner? No problem.
↳ Prefabs go wherever the delivery truck can reach
✓
All-In Pricing. Tax Included.
Foundation, framing, siding, roofing, trim, vents, doors, and labor. No hidden fees, no surprise charges.

What your yard needs: I build in place, so I never need truck access, just a path I can walk 4×8 sheets down. Room for the shed plus about 3 ft to work on 3 sides, and a clear way back to the spot. If it's a long haul from where I park, there's a carry fee (75 to 150 ft +$150, 150 to 250 ft +$300).

Drip Edge & Vents
The metal edge along the roof and the gable vents. White or black, included.
Paint
Paint — Any Sherwin-Williams Color
Sherwin-Williams Emerald® Rain Refresh™
+$540
Not regular paint. Sherwin-Williams' top-of-the-line exterior coating with Self-Cleaning Technology. Dirt washes off when it rains. UV protection prevents fading. Resists peeling and cracking through Midwest winters. Lifetime limited warranty. Your shed stays looking fresh for years with zero maintenance.
The panels need paint either way. LP's 50-year panel warranty calls for a finish coat within 180 days of the build. I paint it, or you do.
Without paint, your shed comes primed tan with white PVC trim.
Painted trim
Standard trim is white PVC that never needs paint. Want the corners, door and window trim in a color? Paintable trim, any color on the list.

Accent color on the doors
Door leaves in a second color, like black doors on a gray shed. $125 per door.

Carrying everything in from the truck is included up to 75 ft; farther than that is a small carry fee (75 to 150 ft +$150, 150 to 250 ft +$300), and stairs, a steep hill, or no gate get priced on the call.
Want to sleep on it or show someone? Every option you picked is saved in the link.
A $4,685 shed that lasts 25+ years works out to just $16/month to own.
It's in your backyard, not across town behind a unit number and a padlock. It adds value to your home. And it looks like it belongs there.
A storage unit? $150/month. And you'll never own a thing.
Thinking about a plastic one? A resin shed this size runs about $2,150, and the makers say 10 to 15 years. Call it two of them over 25 years: $4,300 in plastic, plus the solid base you have to build for it, plus a weekend putting each one together. At the end of it you own nothing.
Half done is fine. I'll help you finish it. Prefer to text? Send the link to this design to 630-802-4016.
Already decided?
50% ($2,343) locks your date. I'll text or call to confirm the details first, then invoice. Nothing is charged online.
