Hannah Mummert is a senior in college studying English at the University of Montevallo. Her dad, Mike, is an amateur, but gifted, carpenter, crafter, plumber, electrician, and all-around handyman, with an actual job in Birmingham. Together they make up the team that dreamed up and built, top to bottom, Hannah’s tiny house. With some help.


Screen Shot 2018-03-03 at 12.19.45 AMBuilding a tiny house started as a joke between Hannah and Mike. She wanted a place to live off campus, in hopes of saving money and becoming more independent. It started with a wrecked travel trailer and a rough drawing on paper of how they wanted the final product to look. They demo’d the RV down to the frame and built it back up as a tiny house. Even though the short-term goal is to have it in an RV park, this tiny house is built to be capable of being completely off the grid.




Tiny House Fast Facts

  • The overall outside dimensions are 27 feet by 8.5 feet with roughly 300 square feet of living space with slide-outs and lofts.
  • The total weight is 14,500 pounds outfitted for full-time living.
  • It is powered by 50 Amp RV service to be able to power the 220V requirement of the Mitsubishi mini-split heat pump (though it only needs 15A).
  • All connections (water, power, sewer) are standard RV hookups because it will spend the first few years of its life in an RV park setting.
  • All appliances are RV-style that are either propane fired or propane capable. Most all lighting is 12V LED, and those that aren’t are 120V LED that are connected through a 2000W inverter, as are most all outlets.
  • The power is broken up through two breaker boxes – one that is for shore power / generator only (electric portion of the water heater, HVAC, microwave, washer/dryer) and one that is powered through the inverter to be battery-powered if off the grid.
  • It is also wired for solar panels and controller in the chance that those are added later. The intent is that the fresh water tank will be filled by a water-catchment system (gutters on the roof) in an off-the grid setting.
  • Currently the bathroom is configured with a standard household toilet since it will be in an RV park setting for a while, but that will be replaced with a composting toilet if it is taken off-grid.
  • Much of the original RV is reused, including the frame (with slide-outs), appliances, fresh and waste water tanks, and more.
  • To handle the weight, the frame was strengthened and the axles replaced with heavier ones to handle the weight. The slide-outs that were part of the original RV were reused, though one had to move forward and be shortened to fit the design. These add an additional 36 square feet and opens up a large area for the living room.
