  • Ultimate Greenhouse 3.5m

    Posted by Gary Fell on 3rd Jul 2018

    I bought this to replace a previous model bought over 24 years ago - for which I cannot fault - as yet not erected - I have only opened the boxes to check the parts, all parts seem to be there.

  • safety greenhouses are a must.

    Replacement for same greenhouse bought in 1999 or 2000 which proved to be excellent, until I cut the hedge down which was acting as wind shield. Not erected yet, only checked parts, all parts there. There should be no trouble erecting the same as the instruction booklet is much improved on the two page leaflet that was issued 14 years ago! The quality is still there. Hope i get as much success as I did from my previous NORFOLK greenhouse.
