420-square-foot ‘big tiny house’

This is a larger than usual tiny house from Michael Janzen. It’s called the 10×42 Carrack because, well, it’s 10-feet by 42-feet. It’s a big tiny house on wheels, technically would be classified as a park model. This type of unit is great if you want to go tiny, but not too tiny.

It’s comfortable, spacious, and still mobile if you ever really wanted or needed to move. The Carrack 1042 is part of Michael Janzen’s new generation of tiny house designs for 2019. Michael says, “It’s wider and longer than most tiny houses but a project sized for many do-it-yourselfers.”

It’s name is inspired by the Carrack class of wooden sailing ships common during the 14th-17th centuries. These ships rode high in the water and had two to four masts rigged with square sails and fore-and-aft triangular lateen sails.

The Carrack 1042 has a large open main room with a small loft accessed by ladder. The main room has a long kitchen on one side and a dining table and french door on the other side.

A small living room, which can be closed-off, joins the main room. This room could also double as a bedroom, office, or guest room with the right choice of transforming furniture.

Under the loft above the main room is a hallway, bathroom, and closet with laundry hookups. The Hallway leads to a dedicated lower level bedroom, shown here with a queen size bed.

Trailers under 10-feet wide are easily moved with an oversize single move permit. Trailers as wide as 14-feet can be moved by truck, but when you exceed 10-feet the permitting challenges grow – not to mention the physical size of the tow vehicle.

A 10×42-foot tiny house will still be easily towed by a full size heavy duty pickup truck, and the single move permit will be easy to get.

    It is still on a trailer; and a bog one at that. So it is still an RV. It comes with a title not a deed. Spend a few more $$ and build a small house on a foundation!

      Tiny Houses shouldn’t be confused with RV’s, as a RV is only designed and built to be a recreational vehicle but a Tiny Houses is designed and built to be a home and has far more in common with a traditional house than a RV… For example, unlike an RV, some THOWs can be taken off their wheels and put into a foundation and aren’t necessarily tied permanently to the trailer and Tiny Houses are generally built to higher standards like traditional houses.

      Besides, there’s a lot of additional costs when building on a foundation… Permits and other fees can add tens of thousands to the cost and is one of the reasons why people choose to put them on wheels as that helps avoid many of those additional costs… Along with reducing other costs like property taxes…

      It also helps get around restrictions as many places impose things like minimum square footage that would block people from just building a tiny house on a foundation or make it their primary residence, which is one of the reasons why ADU’s/Secondary houses are the primary on foundation options for most of the country.

      Though, other restrictions can still make it difficult but options are starting to improve as states like Oregon and Washington have started to become tiny house friendly and Oregon’s Reach Code provides a lot of flexibility to have tiny houses on wheels or on foundations or have one on wheels put on a foundation as long as the building codes are met…

    Do you know of anyone in the St. Marys in Pa. Area that would be able to build this for me ?

    It reminds me on a 40′ shipping container with a different roof shape but 2′ wider.
    I don’t like the four different roof shapes. It increase costs, work and material and what does it provide?
    The loft above the bathroom isn’t suitable for sleeping because iy lacks headroom and can be used for
    storage only.
    I would go for a 40′ high cube shipping container, achieve more width with slide out, chassis are a dime and a dozen, no special permit required.
    It is less work and costs less. Beside that its rock solid, fire resistant, water tight and can easy withstand hurricanes and other natural disaster.

    Everything has trade offs and not all situations will be the same…

    For example, some places ban shipping container conversions. Others can require them to meet the same building codes as local residential houses.

    It may be required to put it permanently on a trailer or weld on axels and wheels to avoid this in those places but features like a slide out would only make sense if you intend to move it regularly anyway.

    Otherwise, just combine multiple containers…

    While roof shapes can effect things like how it handles snow load, whether it’s effective for use in rain catchment, whether it’s optimal for placing roof solar panels, and other things like lighting, heating and cooling of the house as it effects things like solar gain, and simple curb appeal…

    But container conversions aren’t always cost effective, especially when you start scaling to larger sizes or have to do significant work on them then it can quickly cost a lot more.

    Are there any actually built? To see how it really looks and have worked out the bugs in the drawing? I used to work for a high end home builder and learned even the most expensive plans can have flaws.

    To the guy who commented that it is still a RV, a THOW in most states can have the axels and tongue taken off, a brick or other “permanent” foundation be put around,then the title be can be dropped and a deed and mortgage can be obtained. Like a mobile home is. Get out of the dark ages.
