The whole structure should have gone just after the wedding.I agree, but let's remember that SJ is cheap. Grant Hill could only work with the materials he was given. Yes, it's basic but the pergola wasn't meant to be a permanent structure and was put up so Stephanie could have a place to hang her fairy lights for Mummy and Percy's wedding. If the facade rendering goes ahead, it'll have to come down anyway.
For someone who says she's so into restoration and saving a historical château, Steph kept this wooden thing for years.
