We bought the Cotswold Birdlip. It is stunning, well made and strong.
We fervently suggest that if you buy one, use their recommended installers - unless you are an experienced DIY enthusiast.

This is the mistake we made as we would have had to wait two months before an installer could book us in. So we used a local firm which was a disaster.
All the capping strips were installed back to front! We also had to disassemble and refit the doors.
We contacted the support team and spoke to Michael Butcher from technical support who was absolutely brilliant.
We sent photographs of the problem and he sent us a very detailed and comprehensive set of advice and instructions as to how to resolve the issue. We cannot thank Mike enough for his help.
This took us one day but the greenhouse is now perfect and full of plants. Thank you again Mike.
