Basically, floor plan is the first plan that needed to be thought about before starting the tiny house project. Our plan is 7.8m long and on a 2.44m wide trailer. The plan is all depend on our own preference, for example, how long is your trailer? Where would you like to have door and windows? How big are them? Would you like the your kitchen facing the entrance or living room facing the entrance? How long would you prefer for your sleeping loft? Your loft is above kitchen or above living room? and to avoid too many pipes running around in the house, we would prefer kitchen sink, shower place and toilet sink are close enough to each other. we also prefer that the wall facing north side has less window.

To have a better understanding, I also sketched out the plan below:

Below are the plans that we did not use, feel free to use them as your references:
