Build a Kit-based Solar Garden Shed That Doubles as a Greenhouse

For this project, we replace a run-down metal building, encroaching vines, and accumulated junk with a charming, practical and organized solar garden shed that doubles as a greenhouse. The structure is made from a kit that comes with materials and instructions making the new building a cinch to put up.

Step 1

Prepare for the New Solar Garden Shed

Clear vegetation and demolish the old building, leaving the concrete foundation. Purchase your solar garden shed kit in appropriate size and configuration to suit the location and required orientation for light. Inventory kit components against the parts list and assemble tools.

Frame and Cover Four Solar Garden Shed Walls

Measure and Cut Sill Plates for the Solar Garden Shed

Cut pressure-treated two-by-four to length as sill plates for the solar garden shed. Temporarily position them on the slab along the shed's perimeter and drill through the sill plates to mark the slab for bolt holes. Remove the sill plates.

Complete the Solar Garden Shed Roof

Nail a drip cap at the bottom edges of the solar garden shed roof sheathing to prevent water seepage. Horizontally layer overlapping strips of roofing felt across the sheathing. Use a roofing nailer to layer overlapping asphalt shingles.

Install Roof Windows and Finish the Solar Garden Shed

Run double-faced tape along the roof trusses and position the roof windows on top of the tape. Secure windows with metal trim strips. Paint trim. Install latch hardware on the door and grilles in the air vents on the gables.
