I purchased a Petrus Workshop Log Cabin and Interlocking base, the whole service provided and product supplied have proven to be excellent. Good advice available on the Phone and superb service from delivery who covered all the components with plastic sheeting on a rainy day so it remained dry until I could place it under cover at the end of the day. With a good stable base the cabin has not moved and no excessive gaps have formed in any part once settled. Good head height has made it a very useable space as a workshop and is used frequently. I can thoroughly recommend it.
