Well, for lack of a better idea, since you find it a drafty little space. I'm assuming the draft comes in on the right? Most of the necessities in the area are located of the left side; i.e. vent, thermostat, light switch etc. What I would do I think is caulk up the drafty spots, maybe even add sized poster board wrapped in batting I covered in a gorgeous fuscia with diagonal grosgrain ribbons every which way covered with a heavy velvet to be attached to the area above & below the window. (Of course remove the drapes that are hanging in there). This for the purpose of using it as a pin-it board for notes. Attach a table height board covered in felt to carry across the full width of the little room. Leaving just enough space for a comfortable little antique desk chair. Paint the back wall a bright cobalt blue, paint the ceiling a silvery pearlescent white. Find a way to attach a clip-on task lamp. And stretch a heavy duty enough wire across the top of the opening and complete it with a heavy doubled velvet drape with a drooping valance. Place a swag with fringe & jewels on it to be closed when not in use. Voila intrigue is yours!

Your concrete specialist will have ways of sealing/coating the concrete in a low-slip/textured finish. This can be done by texturing the concrete while wet and by using a textured epoxy with low-slip properties. Ask your concrete specialist what they recommend when used in a wet environment such as a shower.

I love your post, there is a blueprint and you are giving out details and whishes witch is making it easier for all of us to help you and your family. This floorplans reminds me a bit about my uncles house. here are some of my thoughs witch you may/or may not use. I am not sure about the NSEV directions which have a major influence in building a house. Parenting so many kids also influence the house and the lifestyle in the home. I would maybe add, or rebuild an ancle to the house prevent from wind on the terrace. Commidded as you sound i would go all in with all of your wishes. I think a big master bathroom is needed to be used as a place to relax with so much to look after. I dont now if your coing to use the door in the lundry room or in the pantry most. I thinks its best to have your garrage entry close to the pantry and kitchen. A open kitchen is also a big decision when you have so many young kids. I would maybe add a breakfast area in the kitchen. SOme other things to consider is maybe the entry and the long hall way. I think you and your family might be a bit tired of the loong hallway. if possible i would switch the entry and the office. to make the entry in to the livingroom, if le librarry is going to be used as a familyroom. A toilet should always be placed near an entry to the house. And an extra toilet is only for u to clean along the way.... I you are looking to expad the family i would maybe build a playroom in the middle of all the kids rooms. At my uncle ealier house theay had a combined office space, guest room, playroom to combind a space for all of the children and their friends to be in. As far as going to design in your home can also maybe influence the layout. I think wood floors or tiles depend on style. I Personally prefer laminet wood floors in the kitchen and entry, but you are to buy some lovely tiles now a day. Pleace ask for a new blueprint suggestion if you are up for some changes. good luck.

@Tribbletrouble44152k7 Trek, no not necessarily.. it fulfills it's purpose if you buy the one that is correct for what you want it for.. a bit of a catch22 and up to the store to point out that the thin stuff may dent.. in fact any of it can... there are many things that will void warranty of laminate floors.. here is a good website dealing with the cleaning and care .. http://www.baneclene.com/articles/laminate-care-consumer.html Remove shoes with spiked or damaged heels before walking on the floor. Spike or stiletto high-heel shoes may cause denting and related damage to wood floors due to the extremely high compressive force they generate. Such footwear can produce dynamic loads in excess of 1,000 pounds per square inch, even when worn by someone of slight or average build. Worth reading the whole thing.. Just worth reminding people that laminate flooring is mdf with a picture of wood printed on the surface with a couple of protective layers of clear coating over the top..it cannot be wet or steamed.. it will swell. Make sure you ask questions.. Wood vinyl planking is very durable and hardy, and bamboo is considered to be one of the strongest timbers.. if you choose to have floors redone with any of the above products please look them up on google and find out the qualities.. I vote for wood vinyl.. looks brilliant, can float or be glued (recommend glue for wet areas such as bathrooms, laundries) is hard wearing and cost is comparable with mid range wood laminate flooring and hardier. Hope that all helps. If you must have wood laminate then go for 10 - 12 mm.. anything less will flex. Must have underlay and be laid on a level floor.. There are self levelling compounds you can use to make this easier... hope all this helps.
