Black Books Inspired Modular Building

The first episode of the Black Books series aired on 29th September in the year 2000, the shop is located in London and I thought it would look great as a modular building. I have created this 4 storey building with the ground floor having a book shop and kitchen/tea room out the back, on the 1st floor there is a living room sort of area with sofa, chair and table. I have left the other two floors empty so you can put in whatever you would like on those floors :) The model is made from 1322...
