Pocket Doors Included!

This storage shed comes standard with a set of wood pocket doors. If swing out doors will get in your way, this is the shed solution for you! Pocket doors provide a smooth opening and keep the weather out when closed and out of sight when open! Doors are structured with a pre-primed wood siding installed over a solid 2x4 frame for superior strength. We use an unfinished white pine trim for exterior design over the siding. Door glides on a heavy duty aluminum track. A galvanized door sill and latch to lock the doors are both included. The pocket doors are shipped ready to install.

Door opening clearance: 5'-5" x 6'-6"

Optional Flooring Package

FortressFloor

Upgrade your Best Barns Shedquarters shed kit with the FortressFloor, a commercial-grade wood flooring system designed to enhance both durability and appearance. This optional floor kit provides a solid, level foundation while raising your building off the ground to protect against moisture and rot. Engineered for heavy-duty use, the kit includes 4x4 pressure-treated runners, 2x4 treated floor joists spaced 16" on center, 3/4" thick 4x8 plywood sheets, and all necessary hardware. Built with premium treated lumber, the FortressFloor is made to withstand demanding loads and harsh climates. Please note that materials are not pre-cut- simple straight cuts are required during assembly. The floor kit ships separately from your building and is delivered by a local lumber dealer, who will contact you to arrange a delivery time. Someone must be present to receive and sign for the delivery. This flooring upgrade is a smart, long-lasting investment in the stability and function of your new structure.

Optional Premium Roof Package

Roof finishing materials not included; Add roofing materials to your shed kit!

Our premium roof package includes everything you need to finish the roof on your new shed! Underlayment, drip edge, 25 year warranty shingles and even a ridge vent are all included. Choose 3 tab shingles in black, gray or brown colors to match your home or style. Getting our roof package delivered on site saves you time and work to buy and transport them locally.

Optional Item

Add optional windows to your shed or garage kit.

Our windows are made of durable aluminum and include decorative, paintable vinyl shutters for each side. They feature lockable frames and integrated screens to help keep both intruders and pests out.

Choose between two sizes: 18"x27" or 18"x36". Both window sizes are compatible with all shed kits. While the 27" high window is generally well-proportioned for a 6'-4" wall, and the 36" high window complements an 8'-1" wall, these recommendations are based on Best Barns' design opinion. Final selection should reflect your personal preference and desired aesthetic.
