A little cheaper than usual! Good spot!
I'm hoping it'd go into rich detail about the planning and construction of the asylums - like architectural drawings, sketches, types of fixtures and fittings often used, and further info about the processes employed in the construction and hopefully a lot more about Hine and Howell and other architects. The RIBA doesn't seem to have much on these subjects, strangely.
I'm making a model of an imagined 1900s-era compact-arrow plan asylum which takes its style off of Hine, with some Howell and dash of Whitmore thrown in, such as elements of Cane Hill and Severalls, together with Hellingly to give a combined summary of these institutions in miniature.. Most of it is just working off of photos and floorplans on here, Simon Cornwell's site, County Asylums etc with some detail provided by the research papers I've downloaded. Very much enjoying this project, though as I don't have the lingo to describe some of the architectural features and elements it's hard to find out more info on things I'd like to know about and/or need to know. I really wanna know what those "spires" are called, and things like that! :-p
