Quick Answer
Assemble the Vego Victorian Greenhouse 8.5ft Wide by following a logical sequence: lay the foundation, build the frame, install the polycarbonate panels, and secure the roof. Focus on leveling the base and using the stainless steel hardware correctly to ensure wind resistance and longevity.
Why Assembly Order Matters
The Vego Victorian Greenhouse uses a classic gable roof design that requires the frame to be fully squared before adding panels. Rushing the base setup is the most common mistake; an uneven foundation can stress the aluminum frame and reduce wind resistance to below the rated 62 mph.
Step-by-Step Assembly Instructions
- Prepare the Foundation: Choose a level site and assemble the base frame on a flat surface like concrete pavers or a wooden deck. Use a spirit level to check all corners; shim if needed. An uneven base will cause the entire structure to twist, making door alignment difficult and reducing wind resistance.
- Assemble the Side and End Walls: Connect the 1.2mm aluminum frame sections using the supplied stainless steel hardware. Do not fully tighten bolts until all wall sections are joined and the frame is square. Check diagonals for equal length. Overtightening early can warp the frame; leave bolts finger-tight until the walls are upright and plumb.
- Erect the Frame and Secure to Base: With help, lift the assembled wall sections onto the base and bolt them down. Install corner braces and cross-bracing as shown in the manual. Recheck plumb and square. Skipping the cross-bracing step compromises the structure’s ability to withstand 62 mph winds.
- Install the Polycarbonate Panels: Slide the double-walled polycarbonate panels into the aluminum channels. Ensure the UV-protected side faces outward (marked on the film). Use the provided gaskets and caps to seal each panel. Installing panels with the UV side inward will cause premature yellowing and cracking within two seasons.
- Assemble and Mount the Roof: Build the gable roof trusses on the ground, then lift them onto the walls. Attach the ridge beam and install the roof panels. Work from one end to the other to maintain alignment. Do not walk on the roof panels; use a ladder and work from inside the greenhouse to attach the final roof sections.
- Install Doors and Hardware: Hang the doors on the stainless steel hinges and adjust the latch mechanism. Add the door handles and any optional accessories like automatic vent openers. Doors may stick if the frame is not perfectly square; adjust the hinges or recheck the foundation if needed.
