There are some bots programs out there which can generate custom buildings such as that brick house. If you don't see it in yours at level 5+, most likely it's a bot.
Btw, bot is a 3rd party program which change the behaviour of the game. Some can even raise your coins, energy or almost anything to the sky.
For you who enjoy playing the game in oldschool way, you should not try any of that bot.
