Honestly hadn't expected it to look this good once assembled. the cedar smells wonderful and the automatic roof vents work exactly as described. freight delivery was straightforward, they called ahead to confirm a time which was helpful.
The T-shaped footprint works really well in our garden and the half-boarded panels give it a more finished look than I expected. took us about three days to assemble with a friend but the mortise and tenon joints made it far less frustrating than other kits i've tackled. customer service was responsive when i had a sizing question before ordering.
We'd been looking at this model for over a year before finally ordering and i'm glad we went for it. the cedar quality is genuinely impressive and the portico really does make it a focal point in the garden. delivery was well coordinated and the team at Venture Beyond answered all our questions before it arrived.
The glass is noticeably heavier than on our old greenhouse and the frame feels very rigid once everything is in place. we had a small issue with one glazing bar during assembly and the team sorted it out quickly with no hassle. overall very pleased with it.
