Palm House, Sefton Park, Liverpool. Mackenzie and Moncur, Ltd. 1896. Restored 2001. There are older, larger and more elaborate Victorian glasshouses than Sefton Park's, but this Grade II* three-tier palm house by Mackenzie and Moncur, who also built the north and south blocks of the temperate house at Kew, is very beautiful. Octagonal, with four entrance porches, it has eight main support beams, which along with the rest of the cast-iron structure hold together 3,710 individually-cut panes of flat glass.
