Has anyone done a modular addition to their current house?

So given there is no way I can sell my house for the price I need to buy a new house, I was thinking of adding a second floor. Has anyone used a modular company to build their second floor? It seems it would take less time to build and may be even cheaper. But I have not spoken to anyone yet, so if you have had experience and have some pointers about the process I would greatly appreciate it. I would also be interested in recommendations of companies too.

Please let me know too, if you find any negatives in doing modular?

TIA

BUMP...

Maybe any thoughts why on not to go modular?

Is this Long Island? Module is not popular out here. Poor craftmanship. And still not cheap.

Just sell your house and take the loss. There is no guarantees you will recoup 100% of your value in adding a dormer.

I would think it would be tricky getting a factory-built module to attach properly to a hand-built, old lower half. There are always bulges and variations in a stick-frame house.

We looked into this when we expanded our home but decided against it because our house is a bit unusual with the design - we couldn't just plop a pre-made on top. But it is an interesting idea. Basically, the boxes come in certain sizes so you can maximize your money if they fit your house (say it comes in a 10 x 20 - if you can use all that size, it's cheaper for you you. If you have to use a 10x15, I think you have to pay the same as a 10x20). There are also accessibility concerns. They will use a crane to lift the box off the truck and put it on your house. If there are electrical or phone wires in the way or the truck and crane can't maneuver on your street, that could cause some issues. Your house needs to be prepped before they deliver (roof ripped off, new plumbing extensions, wiring, etc installed). They will do that for you (for a price, of course).

We looked into this a few years ago so I'm not certain of the exact details, but I think the price was just slightly cheaper than traditional construction. It's just done much faster, of course.

It can be done. Best bet is to start calling up companies for estimates. It may be cheaper it may not be, it depends on a bunch of variables. I would get quotes both way, modular and traditional and then decide.
