Optional Flooring Upgrade – FortressFloor
Take your Best Barns Planner’s Paradise shed to the next level with the FortressFloor, a premium, commercial-grade wood flooring system designed for maximum strength, longevity, and visual appeal. This optional flooring kit creates a stable, level base and elevates your structure off the ground to help prevent moisture damage and rot.
Built for heavy-duty performance, the kit includes:
Crafted from high-quality treated lumber, the FortressFloor is engineered to handle tough conditions and substantial weight loads, making it ideal for long-term use in any climate.
Please note: Materials are not pre-cut, but only straight cuts are needed for assembly. The flooring kit ships separately from the shed and will be delivered by a local lumber supplier, who will contact you to set up a delivery appointment. Someone must be present to receive and sign for the shipment. This upgrade is a smart, durable investment that enhances the stability and functionality of your new shed.

OPTIONAL WINDOWS
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.

**OPTIONAL ITEM
Decorative octagonal gable windows illuminate interiors, beautify exteriors.
**OPTIONAL CUPOLA
Optional Cupola offers an attractive addition to any building and provides ventilation.

We just finished up our backyard build and honestly, I’m pretty happy with this shed kit. The size (12x20) gave us so much more room than our old shed, so now I can actually walk around my tools instead of squeezing past everything.
