Swallow Jay 6x6 Wooden Potting Shed
Excellent and solidly made small greenhouse/shed. Enough room in my back garden for it and surprisingly spacious inside. Love the automatic roof vent.

Swallow Jay 6x6 Wooden Potting Shed
After looking at a few on line we were not sure as the potting shed we liked was a little more expensive than others. Decided to go with it and have to say from start to finish the customer service was excellent. When the potting shed arrived it was assembled and advice given . The quality is second to none and so glad we went for this product
