These instructions are using only parts from 10270 Bookshop set. You need also spare parts from the original set. You will get light and dark version of the handcrafted instructions in PDF and bricklink list in XML.
Inspiration for this build was the official bricklink set Retro Bowling Alley. This build contains some of the features similar to that set.
On the first floor there is small bowling alley with two lines. There is also small bench and shelves for shoes or bowling balls. There are also stairs to the second floor accessible from separate entrance.
On the second floor there is small kitchen and dining room. There is also cooling fan and retro radio.
Outside stairs leads to the third floor. There is a bedroom with fancy old school cupboard and terrarium.
Roof is not accessible but it is nicely decorated.
Instructions are handcrafted in Studio 2.0 with all details and proper views of the build. You should be able to build this modular building without any issues. Please let me know via private message if something will not be clear. I will try to help you.
Enjoy the build!
