Ruby Template Design Pattern folder convention

Requesting a high-level overview of how to structure the directory of a project using the Template Design Pattern in Ruby.

I have a project directory with one venue.rb file & one folder containing base.rb. I see them used a lot in my companies Ruby on Rails project but would like to understand how to structure the project regarding the template design pattern independent of Rails.

Current Setup:

~./project
  +--venue.rb
  +--venue
  |  |
  +--base.rb

venue.rb

require_relative 'venue/base'

class Venue
end

puts "Loaded class Venue:"

a = Venue.new
a.base

~./project/atm/base.rb

module Base
  class Venue
    def base
      puts "base"
    end
  end
end

puts "Loaded module Base:"

When I run the venue.rb I get:

#=> ruby venue.rb
Loaded module Base:
Loaded class Venue:
venue.rb:9:in `<main>': undefined method `base' for #<Venue:0x007fe77209cf20>         
(NoMethodError)

I'm pretty sure I've misunderstood inheritance but I believe this should work. Any suggestions would be appreciated. Thank you in advance.
