Hello,

I am looking for some advice on adding a loft to the left and right sides of a new shed.

I was hoping someone might be able to explain the best way to go about making this work for my particular shed. I will attach photos at the bottom.

Shed: 10x12 (Dutch Barn)

Interior dimensions:

Interior width (OSB to OSB): 9'9" (117")

Interior length (OSB to OSB): Approximately 12' (144")

Floor to top of double top plate: 76.5" (6'4.5")

Floor to interior roof peak: Slightly over 10' (120"+)

Existing construction:

Wall studs: 2×4, spaced 16" on center

Double top plates around the wall perimeter

Roof rafters: 24" on center

Wall sheathing: 7/16" OSB

Floor decking: 5/8" sanded plywood

Treated floor joists: 12" on center

Five pressure-treated 4×4 runners underneath

Loft Proposal: – Two side lofts:

One along each side wall

Each loft: 36" wide × 117" long

I also need shelving added to this shed, so I was thinking it might be possible to add shelving space under the loft and potentially use 2x4 posts…
