Modular and Expandable
Keystone preassembled deck kits come in standard shapes and sizes that fit together as easily as building blocks. Begin with an 8’ x 8’ Keystone Deck starter kit, and grow from there—you can add on to your deck anytime using our 4’ x 4’, 4’ x 8’, and 8’ x 8’ expansion kits.
Completely Portable
All Keystone Decks are designed as free-standing structures, making them completely portable. You can take them anywhere!
Quick and Easy Assembly—Even for Beginners
You don’t need special tools, additional nails or fasteners, or construction experience to build a Keystone Deck. Even a do-it-yourself beginner can build one of our decks with ease—often in less than an hour!

Keystone Connectors Add Strength
Keystone’s heavy-duty connectors are factory-mounted onto our pre-cut deck sections, so you can simply slide the sections together. The connectors’ unique shape makes your deck extra-sturdy, with superior load-bearing strength.
Customizable Designs, Multiple Options
With Keystone’s multiple, functional options and expansion kits, you can customize your deck to make it truly your own. Add an extra stairway using our stairway kit, or add a Keystone Grill Balcony—these are just some of the many options available to you with Keystone Decks.
KDAT Lumber Keeps Its Shape
Keystone Decks are made of KDAT lumber, which means the wood components were dried and pre-shrunk to prevent substantial shrinkage, cupping, or warping. Your deck will keep its shape. And because excess moisture has been removed, KDAT lumber is lighter than standard pressure-treated wood, making Keystone components easier to handle and install.
