Octagon Summerhouse under construction, 2008.

As no image was found of this garden building, thought to have been built by C. W. Bampfylde in the 1750s, the design of the reconstructed Octagon Summerhouse was based on archaeological investigation - in 2006 the original foundations were discovered by archaeologists intact along with some building fragments - and contextual evidence. The latter consisted, in large part, of C. W. Bampfylde’s own design for an octagonal building with crenelated walls for his friend, Henry Fownes Luttrell, MP, of nearby Dunster Castle.
