Being able to build your own house is a wonderful opportunity, and when you should be able to customize it best to your own personal needs. So you'd need to be more specific about your family & lifestyle .. how many bedrooms & bathrooms do you want/need? How old are each of the family members? Will the house be detached, semi-attached or attached .. which controls window placement? Do you have a casual or formal lifestyle, want individual rooms, or open concept? Does family do a lot of cooking, and have activity revolve around the kitchen? Does that "triplex" include a basement and/or garage? Bottom line, is that "the best ever designed plan" might be totally different for you, than me, so a designer needs more details from you!

How do you decorate your place, what kind of style, colors, and feelings? That will greatly influence the type of door you might want. Also, think of your budget, and whether you want to install it yourself or hire a professional (you don't need to tell us, just keep that in mind). Then look around Houzz, in the products page, they have lots of interior sliding doors and hinged ones, from elegant frosted glass in a dark wood frame, to rustic reclaimed wood planks. You may not want to purchase that exact model, but it might give you a better idea of what would fulfill your airflow needs without sacrificing style.

The amazing thing is that you have the luxury of approaching the architect about these issues. Laminated glass should address the security along with any alarm or security system you plan on installing, though the laminated glass may have size limitations. Regarding the waterproofing you should contact the architect, contactor and waterproofing subcontractor, or see about hiring an independent waterproofing specialist who can detail and warranty the condition. As a design consideration, make the lower area a garden or gallery or sculpture area and upper should be all glass. Maybe a garden roof there too if accessible or visible. In any case looks like an amazing place!!

Your rugs are beautiful and very good quality. They compliment your property well. It is natural for wool to shed at first, but it will eventually stop. You can get a special carpet rake or use a broom to rake or brush the carpet weekly and also vacuum it once or twice a week. The shedding should stop after a few months. Once you get through that period, you can enjoy the many great qualities that wool has. It is extremely durable, more stain resistant than most, flame retardant and self-extinguishing, and it actually regulates temperature & humidity in the home by absorbing & releasing moisture as needed. That's how it amazingly feels warmer in the winter and cooler in the summer. Good luck! Don't give up on your rugs just yet!
