Building the Fencl

Over the spring of 2009 we built our largest home on wheels, the Fencl. This small house is 130 square feet and features a kitchen, bathroom, sleeping loft, fireplace and much more.

How long did it take to build?

A crew 4 built this house over 10 weeks. We spent 825 hours to purchase materials and build this green design house.

How much did it cost to build?

When all was said and done we spent $19,148. We shopped around and shaved almost $2,000 from the cost when he found a trailer 100 miles away at a much lower cost.

Build one myself?

Depending on your skill level and determination it is possible to build a mobile home for a fraction of the cost of buying on already built. We do recommend hiring licensed contractors for the plumbing and electric work. When we build a house we hire specialist for those tasks. Typically, the electrician and plumber are the highest paid people per hour, so we keep the amount of their work limited to just those two areas. We spent less than $2000 to have that work completed on the Fencl. When we build a small house we usually hire a finish carpenter as the job foreman. We keep the number of workers at any given time to 2 or 3. Aside from the finish carpenter and electrician and plumber, the other crew doesn't need as much experience.

 

Buy this house from Tumbleweed?

This green home can be purchased for $53,997 plus shipping and applicable tax.

Is the price negotiable?

We price our homes and home plans with a very low markup. We do not leave room in our pricing for a discount. Our expenses are subsidized by selling ad space on our website and by the sale of our books. We are proud of the fact that we pay our crew a fair US wage with insurance.

Salvaged RV into a Tiny House

damaged-rv-trailer

Salvaging an old or destroyed RV trailer can be a great way to furnish your tiny house. Many salvageable items can be claimed from an old trailer to be used again in a tiny house on wheels.

The above photo shows a 32 foot trailer that was listed in Kentucky for $600. The side was ripped off but the owner still had the sink, tub and other appliances available that were included in the purchase. Watch your local craigslist for bargains like these or check around your town, you may find someone who would be happy for you to take it, just to get it out of their way.

The base trailer was not damaged so the the outer shell could be completely removed and you would than have a 32 foot trailer to build your tiny house on. You could than salvage all the internal items, such as the electrical control system, plumbing and water supply. Re-use the furniture and cabinets and incorporate the kitchen appliances and bathroom toilet and tub into your tiny house.

What is not salvageable you could take to the dump or donate to a local charity organization. Below are a list of three things that you should consider as options when using an old RV.

  1. RV components are designed to withstand trailering long distances, are made to be turned off for many months, so they are very durable.
  2. Most RV’s utilize 12 volt direct current systems or DC electricity, so generally use 12 volt appliances. However they usually have an inverter for when they are plugged into a grid which converts everything back to AC usage. Most inverters will transfer back and forth automatically.
  3. Many RV’s have portable gas stoves that can be moved in and out of your home. Many of the new bathrooms are one peace and incorporate everything in them form tub to toilet, so this can make setting up your new space a relatively easy process.

So keep your eyes open at your local craigslist and ebay for a great deal and you may find that you will have just about all the items you need for furnishing your tiny home. by Kent Griswold

Off-Grid Power Station

powerstation1

In the previous two posts we discussed a couple of off-grid options. Wind and Solar and how they can generate power for your tiny home.

For both these power sources you need a place to store and distribute the power. In this article I will show you a basic power station set up to run a tiny house on a part time basis.

This unit consists of a box that contains all of your storage requirements. Propane to fuel your stove and hot water heater and batteries and inverter to power your electrical needs.

powerbox-assembly

Here is the basic box under construction. Built with three compartments. The right one holds your propane bottle.

The top left is for your inverter and meters and wiring. The bottom left holds two batteries for your storage which is generated from either your solar or wind power or both if you are set up that way.

wiring

The next photo shows the inverter and the wiring involved with the setup. One cord coming up from the batteries and the second one going into the inverter to convert the electricity to the right output.

meter

In the following photograph you see the meter that lets you know the status of your charge, etc. battery-connection

The next photo shows the connections to the battery and the wiring going up to the inverter.

batteries

Following are the two batteries that power this unit. This power station is set up as a camping unit which is mainly used on weekends so two batteries are sufficient. If you are living in your home full time more batteries may be required to fill your needs.

This photo shows the completed unit with the exterior wiring and switches and adaptors for bringing in the power and also using it externally.

This article is not a how to article but an illustration of a power station set up. You should consult a professional in setting up your home power unit so that it is done the right way and you can sleep peacefully knowing that your power unit is working properly.

Off-Grid Wind Power

windturbine

Wind power is a great source of energy in some areas of the country. If you live near the coast or in the desert you will have a steady stream of wind on a regular basis. In other areas of the country the wind may not be as consistent so wind power may not be the best option.

Where I live it the winds pick up usually for two or three hours in the late afternoon, so wind energy would make a good back up source to solar energy as we get a high amount of sun in this part of the country.

There are many type of wind generators out there from extremely large to small. For a tiny house on wheels you might consider a marine type wind generator as these are small and can be rigged to fold up or down for travel. They have few moving parts so are very dependable and surprisingly affordable.

Rooftop generators are becoming a hot item and there are several versions being designed with the goal to make them affordable and available to the masses. I discovered this neat link to a website that shows several of these ideas in movie form. To learn more visit the The Rhode Island Alliance For Clean Energy and the page Residential Wind Power.

The following video proves that wind power can be built and manufactured using recycled materials and very inexpensively. How would you like to use everyday recycled products to manufacture residential wind turbines, which will give you your own energy independence!

As with any type of off-grid power you will need a way to store your energy and your power station will need the correct inverters and batteries to make your  home fully independent. Below is a picture of a power station with the batteries, inverter and connections all in one unit. This one is designed to have a nice size propane container built in also.

img_6258

This unit is set up to accept the wind generators power, plus connect solar panels also. With the propane setup you could also install a propane generator for back up purposes.

Hopefully, this article will inspire you to research the wind energy potential out there and you will figure out the best solution for your current and future needs. Wind is a free source of power, you just need a good way to harness it and store it.

Please add any suggestions and/or resources to the comment section below.

Mobile Solar SolMan

Adding Solar to your tiny house can be a daunting task if you are not up to date on all the latest technology and how it works together. 082

A couple of weeks ago we had a "Meeting of the Tiny Minds" and Bill Kastrinos of Tortoise Shell Homes told Stephen, Michael and I about this great solar solution that was out there.

What if there was a simple solution to this and all you had to do was plug and play? SoleMan a company based in Willits, California has come up with just that kind of solution.

They call their system the "one small, easy to move, all in one integrated unit, ready to point towards the sun at your best location, and deliver up to 1200 watts of AC power, and 12 volts DC power, and even charge all your Ni-Mh smaller batteries."

This little unit is on heavy duty bicycle wheels so you can have your Tumbleweed home in the shade and easily roll your solar unit where it gets the most sun.

084

The cool thing about the SolMan is that if your needs grow, so can the SoleMan. You can add another solar panel easily and even a third. The second one sits on it is own stand and can be adjusted as needed. If you chose to get a third panel they have a bracket that attaches all three together that can be folded up for moving. No need to deal with big panels and connecting them to your roof and knowing you have to park your home in the sun to get the most voltage to your system. Here are list of the SolMan features:

  1. Silent Operation: No sound whatsoever. Won't bother your neighbors or you with gas generator noise.
  2. Clean Operation: No gas needed, no gas cans to transport, no fumes or exhaust to worry about.
  3. No additional costs EVER! : Once you buy a Solman, it doesn't cost anything else to run, as long as you can point it towards the sun.
  4. No recurring gasoline costs, that are only going to go up, no oil changes, no short life span, as unit is designed to keep working for years. ( 20 year PV panel warranty)
  5. Completely self contained, integrated unit: Ready to go, plug and play green power. No engineering or electrical skills needed.
  6. Transportable: With ramps, the Solman can go with you in the back of a small van, SUV or truck. It can be laid horizontal safely.
  7. Mobility: 26 inch heavy duty aluminum spoke and rubber bike tires and perfect balance allow the unit to be wheeled to any location for the best sun, and can easily be turned thru the day for maximum solar tracking and optimal PV energy input.
  8. Deep Cycle Batteries: "2 or 3 -100 (200 to 300 amp-hr total) deep cycle sealed gel cell. No acid spills or venting. No maintenance.
  9. Enclosed battery Container: Optimizes battery life.
  10. Two 12 Volt Auto Plugs: Plenty of places to plug in your 12 volt accessories, lights, chargers, etc.
  11. One heavy 30 amp marine trolling motor plug on exterior, for water pumping, external battery charging, or additional external inverter.
  12. All external plugs have covers and are set up for outdoor use, even in the rain, and all critical components are inside and protected from the weather.
  13. Array only switch: to route unused, excess PV power during the day to external battery charging or water pumping.
  14. Blue Sky Solar Boost 2000E MPPT PV Charge Controller: can handle up to 25 amps or 3 PV panels, and Maximum Power Point Tracking gives additional 10% to 20% charging efficiency to PV input.
  15. 120 Volt Magnum MM-AE 1200 watt Inverter/Charger: this unit has a built in 70 amp charger for when your batteries are down, and you have access to a gas generator, or the grid, you can just plug in the unit and bring your battery bank up to full charge in as little as two hours, also has an AC transfer switch, that automatically senses external power and switches load to that when on.
  16. Magnum Inverter remote switch and status lights on back of unit.
  17. Fuse Protected: 150 amp inverter fuse, triplex plug 20 amp and exterior 30 amp plug.
  18. Heavy 15 amp solar PV-in plug, wired to solar controller for adding an external solar panels.
  19. Toe piece L on bottom, allows for easy transport of optional external PV panel.
  20. Solar PV panel hinged for easy access to internal box, and latches and locks if needed.

So if you are looking to take your tiny house off the grid and become independent and want to use solar as your main component this SolMan option is worth looking at. Of course there other other RV and home options so do your research and choose what is best for you and your situation. I just like the idea of plug and play and having everything put together where you need it and mobile to boot. by Kent Griswold
