Pre-Fab Homes?
itwerx asks: "I am considering purchasing a pre-fabricated home to put on an empty lot in an urban area. I have researched hither and yon and Googled to my heart's content and found great gobs of information online. The question here is what the SlashDot community's own experience has been with this type of technology? Anybody purchase a pre-fab home recently? What was your experience like?"
I work in construction, we've worked on a few modular homes and from what i've seen you can find some well build ones.
We did some repair work on one last winter, a tree had fell on the house and it was barely damaged.
This particular house was build WAY above code, it was very empressive. I wish i knew who manufactured it, i would have recommended them highly.
Surely the geeky thing to do is casemod an existing home. What you could do is add a window, and put some lights on the inside, so making the internals visi... I'll get my coat.
You are not alone. This is not normal. None of this is normal.
Check with the manufacturer, ask for details on how it's constructed. They've been required since the mid-80s to build them to at least HUD code and since they're generally shipped down the road in pieces, each piece is usually sturdier than many "stick-built" homes (in order to survive the trip).
:D Also, prices vary from dealer to dealer (even with the same manufacturer), so you may be able to drive an extra hour or two and save yourself a few thousand bucks.
Even with these requirements, there's still a _very_ wide range of construction quality, both exterior and interior. Shop around, walk through a few lots physically. Beware, we work on commission. Don't seem too interested or you may find yourself sitting at a table with a pen
As for the houses themselves, there are several different types (manufactured, modular, etc.) each with their own features and price ranges. I sell manufactured homes. They have their own shipping frame built into the bottom of the house. The structural benefits make construction less expensive for the manufacturer, but as a result they're built less like a stick-built home than a modular is (where rooms are preconstructed, minus foundation, and shipped to the site). Also, much of the construction contains OSB (oriented strand board) which can cause problems for severe asthmatics due to possible low-level formaldehyde release from the bonding adhesives. Most modern homes actually use this material in one place or another, it's just more prevalent in a manufactured home. If you're worried, look for adequate ventilation in the construction. As a side note, I've worked 8 hours a day (sometimes more), 5 days a week in one (for an office) for a few years and feel fine.
I actually got into the business when my wife and I moved and were looking for a new home. We considered a manufactured home, but eventually settled for stick-built. Here's why: the house was already built, all we had to do was pay a price. With paperwork, site-work and build-time, a manufactured home can go up in as short as 2 months. This is _extremely_ fast in comparison to constructing a stick-built home, plus you have a considerable amount of 'customization' available (at roughly half the cost per square foot). However, it _is_ a construction site and will probably end up being a construction loan. Be prepared for it to take time and you'll need to be in constant contact with your salesman and bank.
As for the prior poster who wrote: "If the soil is clay or too rocky, you could spend as much as 50-75k putting in a septic system!", I can honestly say I've _never_ seen a system cost that much. Maybe it's just where we live, but high end systems here run just under $20k, while the average is $12k. You will need to be sure of: Electrical access, septic rated for the house you order, site-work for the foundation, garage (?), access for getting the pieces of house on-site, etc. There are a lot of costs that aren't included in the house, _make sure you get it all up front before you sign_.
All said and done, manufactured homes are a great way to go for a semi-customizable home at about half the cost of building your own. You'll probably be limited to a single floor (2 story homes are still a rarity, but they exist), but we've got some that are in excess of 2700 sqft. I really like the product and may end up living in one at some point in the future. Good luck in your research.
