Great extension
The extension came as part of the 11x18 package and we added an additional 2.5 ft extension to the overall shed. Competitive Edge is a great company to work with. Fast shipping and Customer service was quick on responding to the questions I had. Bit of a problem with the window latches on the shed, but my husband contacted Lifetime and the issue was resolved.

Great Extension, Slight Fit Issues
Just as easy to assemble as the shed. didn't follow the directions by only removing one section of the shed and sliding it apart due to the fact I was relocating the entire shed. Shed is 2 years old and every new extension piece seemed to be an inch longer than the existing pieces. didn't cause too much issue on the walls and ceiling besides having a slight gap, but the floor would not fit together without trimming some of the lock tabs
