floor joist span

Hi,

DIYer here, I am building a small house that will be built off site and done in three stages.

Stage one is a 12’ wide (left to right) and 30’ depth (front yo back) next two stages will be built at site and will be about the same size as stage one and will all be attached to each other which would make a 30’ by 45’ roughly (not fully decided on end size as in left to right part.

Okay with that said I am trying to figure out the best way to do the floor joist for stage one? Any ideas? The first part of the building will be moved by a trailer like they use for moving a portable shed.

Thank you and looking forward to the ideas and advice.

    Drawings and a local architect would be helpful, not necessarily in that order.

    and an engineer. moving a finished product adds an entirely new dimension to something that is usually designed and built on site.

    Having lived in a house that was moved, where nothing was straight, and all rather loosely connected as a result, DON’T. Not unless you are hiring a modular builder who understands all of the stressors that toddling down the highway at 30 mph puts on connectors and the concepts of level, plumb, and coplanar. Get the experts involved at the Concept level. Before wasting a minute on Design that doesn’t work. Much less a single box of screws on any Build portion.

    I've built small buildings that were moved. Once a wood frame structure is sheathed it is amazingly rigid. The floor joists are the simplest part of it. Just design to clear span the width and to cantilever whatever the mover tells you his supports are. Then go up one size. The rest is more important: depending on your design and materials you may need to temporarily brace, maybe install windows later. What kind of siding, roof or openings are you planning?

    I am planning to install as little windows or even siding, drywall etc to it’s moved. The thing that worries me the most is the toilet that will be in it. Most other things will not be finished till it’s moved. Vinyl flooring will be used a kitchen sink

    Don't use the toilet until the building is in its final resting place.

    Good advice for a good life.

    Excuse me, but you're in over your head. Hire an experienced framer, not an architect, not an engineer, a framer, and do just what he says please.

    The reason I suggested an architect is because I thought a good one will talk you out of what you are planning on doing.

    As mentioned above, the phase one structure will have to be designed and built to act as a building and a trailer (or sports car depending on who's pulling it). It just doesn't sound like a good idea. A framer with the right experience may be hard to find; and any architect, framer, engineer, or anyone else may not want to take on the liability without extensive signatures on several waivers. Don't hire the framer that was hired to demolish a garage from one of my projects, he decided to try to move it instead. That's him under the window. (just kidding, that's not him)

    Mark-

    I think the detritus on the roof caused the problem.

    If Phase 2&3 can be site built, then so can Phase 1. None of this makes any sense. Neither logistically or financially. Certainly not structurally.

    Ok a 12’wide house? So framing takes up 1’ and pathways another 3’ which leaves usable living space at only 8’ wide.
