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.

This is second option where bathroom has been removed from the front room from left hand side..

I am so happy to see you here! I will have to go back and see if i can retrieve my posts... thought I would make them into a little book for my daughter, with photos. Quick run-down on the bathroom (not travels, no time) - The kitchen has a rather elegant sliding door with beveled glass panels. Painted white, since this was the original colour. GD's new bathroom has the doors I had picked earlier; i thought of polishing them but decided sprayed automobile paint (on a resin primer) would wear better. Especially since it is such a small bathroom, and she is so splashy. I have this finish in my kitchen and it has lasted 15 years now. A tad chipped here and there, but only needs a wipe down once a week. Same finish for the balcony doors, also split like the bathroom. We have a new wardrobe, a study table with built-in shelves, and a small chest of drawers for her odds and ends. I want to re-tile the tiny balcony, more as a little statement. Currently we are looking at Portuguese tiles, though I did think a mosaic with a funky cat might be nice. Let me see the costing. The room will be painted a neutral adobe, with bright white woodwork and an off-white ceiling. This means she can go wild with cushions and covers. Other changes in the flat; We have changed the glass in the master bedroom and living room from small cramped panes to a single pane for each section with a 1" bevel all round. Doubles the cost of the glass, but looks so elegant! The air-conditioning is being re-located. The compressors were all mounted in the bedroom and living room balconies, which looked terrible and meant the balconies (very narrow, only 30" deep) couldn't be used for anything. Not even plants. So they are being moved so that the compressors can be mounted at the rear of the building. two down, one to go. Now we can put in some nice plants, fishtail palms etc. The kitchen counter on one side came out intact and will be reused elsewhere. I am planning overhead storage, cupboards, and a draining cupboard for plates and glasses. Right now there is no dish washer, though a place is earmarked, but for now I will put in a cupboard with steel racks for cups, glasses and plates, all hidden behind pressed glass doors. This is all in the planning stage.... Pictures in a little while, they are mostly on my ipad and don't transfer well to the mac. They come without numbers... so I have to rename the or something. Somebody tell me how to do this!

Seems weird not to incorporate it into the design -- I'm all about having things "look intentional" rather than working around them later. Like could the island have connected to this, rather than extending past it? or been L-shaped, so there's room for an extra stool, and also a wall cabinet? Anyway, hard to discuss that in the abstract without kitchen plans. I'm with miacometlady's original advice to not worry about it right now, and decide how to deal with it once the bulk of your kitchen is in place. You might find that you hardly notice it, with all the beautiful new finishes, or it might seem obvious to put some stainless or glass shelves there, or maybe simple is best and one simple hanging picture does the job. Don't stress about it until After. :)
