I came across this about Kayseri's traditional houses.

Vacit Imamoglu, Traditional Dwellings in Kayseri. Geleneksel Kayseri Evleri (Ankara: HALKBANK Kultur Yayinlari, 1992)
And the photographs are at:

Alas, almost all of the houses depicted in the photographs are now demolished. Even in the 1980s the author was describing old Kayseri as looking like a bomb-site, which is exactly what I thought it looked like in the mid-1990s.
In his footnotes, he makes a brief comment on the doubtfulness of their being any such thing as an "Ottoman-Turkish house type". He mentions that the idea of such a classification was formulated by a Prof. Sedat Hakki Eldem. Does anyone know in what period he did this, under what circumstances, and in what books.
I had an encounter last summer with a vile individual in Kars, name of John Hurd, from the Global Heritage Fund who are, come spring, going to demolish every house in the old disticts of Kars and rebuild it full of fake "Ottoman-Turkish houses". He literally blew his top when I dared to say that there never were any "Ottoman-Turkish" houses in Kars, and that there actually was no such thing as an "Ottoman Turkish house" east of Ankara.
