For building a house,we usually consider wood,brick,concrete and light steel.At modern time,people often consider 

concrete or steel.A thick concrete wall can keep the house cool.Steel will make your house hot unless you insulated 

the walls well.From a safety standpoint,a steel beam will fail significantly faster that a wood one.It's true steel melts 

and fails faster,but at a much higher temperature than wood burns.Choosing light steel frame houses would be

 a good idea because steel is obviously stronger than wood and it provides more strength to house than wood can 

provide.It will surely be more expensive than wood but it will be far better than wood in the long run.

Would you like to choose light steel frame houses?I guess you need to consider the conditions where you live

like earthquakes,wildfires,tornadoes,floods and termites.You will need concrete for the foundation.There is probably 

a combination of the two that will suit your needs best.It would be helpful to know what you want to achieve by using 

steel.There are advantages to both.Floor and roof spans can be lighter and quicker to build with steel,but the roof 

will get hotter and therefore need good insulation and need to be well ventilated.
