This kit includes parts to extend both door frames, making it a complete two-door solution. The other extension kits ($379 and $439) cover a single door each.

The standard Riga base frame raises the greenhouse by 6 inches. Whether you need the door frame extension depends on the total height of your foundation. If you are installing on a raised concrete pad, timber platform, or other elevated foundation that significantly raises the greenhouse above ground level, this kit is recommended. Contact us with your foundation height and we’ll confirm whether the extension kit is needed.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy is free shipping only available when purchased with a greenhouse?\u003c\/strong\u003e\u003cbr\u003eThe door frame extension kit ships free when ordered together with a Riga greenhouse because it can be included in the same shipment.
