Assembly Tips

Assembly is easy, even without experience. Depending on size & options, it may take a weekend & 2-3 adults. Consider hiring a handyman or contractor- affordable online at AngiesList or HomeAdvisor. Read the assembly manual near the bottom of this page. Prepare a level, square foundation- best with concrete. Remove grass & weeds; cover with a weed control mat. Concrete slabs freeze & impede temp regulation. Add a path down the center with flagstones, bricks, or decking.

Staff Recommendations:

• Note: Please be sure to check your local building code for any required permits
• Please contact us with any questions; lead time is 1-4 weeks, and returns are costly.
• Maintenance-free design means the Riga only needs occasional washing with a garden hose and recommended annual tightening of all nuts and bolts
