So much can happen on an exterior...trim, exposed rafters, doors, windows, siding, stone, brick, stucco, roofing, gutters and downspouts....hire an architect or a design/build firm to help answer these questions prior to building....like hiring an interior designer for help with furniture, these professionals will help decide the style of the exterior of the house and how that style interacts with the function of the house.

That explains his opinion. Your description until now was for outlay doors. Slideline 16 is capable for 50-60 kg and 18-24 mm doors only. As I said earlier, not a big fan of bottom running sliding systems. Hope it works fine for you. Steel decorative strip is possible . But avoid deep cuts on the door that would increase the chances of bend/warp.

Farooq, First one is a glass finish Subway tile. It looks good but many people back out due to budget issues as it is relatively costlier. Second image is of a brick cladding wall paper. However, similar looking ceramic tiles, mud tiles are also available locally. IMHO, red brick sand tile gives a more natural effect.What suits better would depend on the overall design of the house.

Yes. You can fix heavy duty fastners in slab. Just check out the fixing detail on youtube.
