A thick concrete wall can keep your house cool. Steel will make your house hot unless you insulated the walls well. Insulated walls don't work very well in a flood zone. When they get wet, you need to tear them apart. You will need concrete for the foundation most likely unless you are driving steel pylons. 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. Steel floors can be cantilevered further. It is easier to make bigger window openings. 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. These are just general assumptions of certain building practices so that you know what to ask people where you live. The practices and resources vary from place to place and building something for a specific purpose can change the benefits of one material or the other. My best guess is that you will probably want to use both.

Its a really lovely room! what a great place for kids to share. I like kids sharing rooms. I think you need another colour to tie it together. I would suggest a blue tone.... teal, navy blue, duck egg blue. to tie it together. Its a little to pale and looks sparse, but actually isn't. I would leave everything exactly as is, BUT, paint the back wall behind the bed teal and find a simple navy blue wall decal that is fun and kid- like maybe one with a sillouette of a boy and girl playing. I would paint the wall behind the sofa duck egg blue. Then I think it would suit both kids more and look more kid friendly. the blues will balance the pink and cream, but because you have a pale carpet i don't think it will look too dark. don't worry about making it totally kid like, its a room they will grow with, not a kindergarten, and it also needs to peaceful and restful for sleeping. besides with their art on the walls and bright toys everywhere it soon looks bright and kid like. Good luck!

Ideally master bedroom should be located in southern part of the house and all other bedrooms should be located either towards the East or North of master bedroom. Master bedroom may be located in south-west of the house. This room should be used by the head of the family and eldest son of the family. South portion is also recommended for eldest son bedroom. If there is more than one floor, the head of the family should have his bed room in south-west direction on first floor. This bedroom should not be used by young children otherwise unnecessary quarrels can take place in the house. A west sided bedroom is good for children. An eastern bedroom can be used for children. But this room should not be used by newly wed couples because it can cause unnecessary quarrel between the couple. Teenager girls should have their bedrooms in north-west direction. The bedroom should not be constructed in central portion of the house or in basement as it may lead to mental tension. Also bed room should not be constructed above porch and kitchen. An attached bathroom can be in north-west or south-east of bedroom. Taken from this website : http://www.bestastrologer.asia/bedroom-vaastu.html Which is very informative !

I have some suggestions if you are thinking budget friendly changes. Make a photo gallery with different size frames and arrange them parallel to the stairs, so you can enjoy each photo as you climb up. And for the area that will be on a level with your upper floor, try some pretty decal that will connect the photo gallery to upper level. And last, if you have budget add some beautiful hanging lights in the stairwell. Also think about repositioning your refrigerator.
