Leading on from the last point, weight is a huge issue to be considered when designing and building a tiny house. If the house is designed to be transportable, lightweight materials must be used to minimize the weight of the house. If built on a trailer, you must also consider “tongue weight,” meaning how much weight is on the front, toward the tongue of the trailer, and how much weight is on the back. If there isn’t enough weight on the trailer tongue, it can end up swaying from side to side when transporting the house, and if there is too much weight, it can overload the tires and push the vehicle around. Both situations can be extremely dangerous, so calculating the weight of the house is essential.
