Brian, You can build a metal bldg. with Foam panels (metal skin inside &
out) on the walls & roof and get a heck of an insulation factor plus a
completely open bldg. free of internal supports. You can free span 150+ feet
if you want and go to 20, 30, 40 foot eaves as well.

However, I really believe you need to decide, and list, a definitive set of
parameters that will fit what you're looking for to get some best result
answers here. Anything can be done as long as you have the money to pay for
it......Anything else is probably guesswork from any responses you'll get
here....

Appreciate your almost steely conviction about this newer method.In
fact,I do wonder how, with so much possibility of DIY using steel,
there are not a lot of people who prefer or argue in favour of
building steel houses.The problems may be deeper than what they appear
to be upfront, especially those from the cost of pioneering.Due to
exports,steel is now more expensive than before.Those who follow are
wiser about earlier pitfalls. Some ideas:

A rudimentary computer stress analysis or calculation for structural
loads, especially at stress concentrating joints.

Lightning conductors and circuit breakers against danger of
electrocution.

Aesthetics and neighbourhood issues. A cuboid steel house may be an
eyesore in spite of other advantages and could be pulled down in court
action.

A limited sponsorship from the steel builders, who could offer
readymade structural elements not yet available in Home Depot.

A regular contact by blogging on the net among interested steel house
builders. An individual's gutsy is a thing apart, combined action could
build a quicker all around confidence.

Benefit of high strength from wind loads and earthquake.The latter
advantage is an advantage for example in CA when two steel floors can
be more easily implemented due to extra structural stiffness. etc..

Good Luck. Narasimham

Ever seen a Lustron house? A very interesting concept that didn't quite
catch on, but very durable.


Posted by Raider Bill on October 20, 2006, 10:38 am
Well, I'm back to a wood frame house 3-2 with attached 2.5 garage. I
like the Barn home look, something like 40x 48 with a 24x40
greatroom/kitchen. Single story with a 12 ft ceiling peak in the great
room. Bedrooms would be on either end and attached garage in back.
My shop will still probaley be metal but detached and out of sight.
Now the next questions, post and beam or stick frame?, crwal space or
slab on grade, regular or extra crispy..................
I like the post and beam inside look.
My brain is on overload...............

Help!

Bill:

For energy efficient post and beam you might think about using SIPS. You
erect the post and beam frame then infill with SIPS. They provide both
lateral force resistance and energy (and sound) resistance.

SIPS work best in rectangular structures and can be used for energy
efficient roof structures too. This type of construction is not the least
expensive, but the house will go together very quickly and the energy
savings can pretty quickly amortize the extra constructions cost.

As for foundations, I generally like to see crawl space or basement to
allow for easy access in the future. However, if you want one story with
in-slab radiant heat, that's not a bad system either. The high ceilings
make the use of radiant heat a good choice -- these systems tend to keep a
comfort zone in the 7 feet or so closest to the floor and the rest is
cooler.
