How to Extend your Victorian Terraced House

[Green and Teggin]

I am a local architect and I am in the middle of compiling a book of ideas for extending a Victorian terraced house. This book will consist of various case studies of different kinds/sizes of Victorian terraced house, showing different plan options (annotated) for each floor with photos or 3D sketches showing how these ideas would look.

I have had publishing offers from the RIBA (10% of book sales, they pay for all production and distribution) and Artifice (33% of book sales, but I pay 50% of publishing and distribution costs, which I think will amount to holf of around ?40,000 for 1000 copies). Neither seems that attractive. I am therefore turning to you to ask your advice. Should I go with one of the offers or do I risk it and self publish? One of the big questions is how many copies do I think will sell. There currently isn't anything else like it on the market.

What do you think? Do you think it will sell? Would you buy it? Anyone had experience of publishing?

Any advice much appreciated
