Assemble the bed following the manufacturer instructions. We moved the bookshelf section to the outside of the under bed area and also lowered the foot rails down below the mattress height for easy access from the stairs in the middle of the two beds.

Cut 18 inches from each of the bed posts from the extra loft bed kit. These will be added between the lower section of the loft bed and the upper bed section.

Drill holes in the center of each extension post at the top and the bottom.,

Use the extra hardware and a few extra dowel pins to attach the bed post extensions to the original bed posts.

Reassemble the bed with the leg extensions between the lower section and the bed frame section.

Add a few flat braces (mending brackets) to the back legs where they are less visible.

(Optional) Add extra bed slats to the mattress platform and screw them into the frame to help the bed be more stable and comfortable.

It's important to secure the high loft bed to the wall for extra security. Attach it to the wall with a few screws into studs or using drywall wingnut anchors.

We also secured the loft beds together via the bookshelves so they were ready for the stairs!

Build a platform frame for the landing using extra unused pieces from the bed kits.

Place the frame on top the bookcases and attach it to the bookcases, the beds, and the wall.

Attach the cut and stained 2x6 boards to create the landing.

Build the steps of the stairs using extra pieces from the bed kit as the stringers and 2x6 as the treads.

Use the extra pieces from the beds/ladders to build the stair railings.
