Thanks Pragati, it looked to me like some sort of high polished quartz stone and if this was the case there would be a way to hide these joints by filling them with an appropriate material and polish them thereafter. So I guess, the framing-idea with the LED-Strips which pollyannagal mentioned would be a good option. You could also tape some sort of accent-tape over the joints or even just LED-Strips to hide these ugly joints. Cheers Bertram

There is contrast between the traditional furniture and the focal point of the floor which pops, draws attention. I would recover the sofas in cream colored soft fabric - suede. I would leave the curtains grey, and put down a large neutral area rug. The edges of the room would show the pattern of the floor. I would color the wall and add texture to it, but not too dark as the room will appear smaller. Add a picture and put a nice plant holder, large vase in the left corner of the room - an oriental-style vase. Or, a cream-stripe fabric on the sofas. You could go soft or bold in this room - depending on your taste.

I have tumbled travertine (basically a form of marble) in the master bedroom and a marble mosaic in the master bath. It is higher maintenance. It stains and it wears differently in different areas. I am not doing natural stone in my new home. There are some fantastic tiles now that mimic all the stones, and a good quality porcelain tile will be very durable. Some ceramic wall tiles are "weaker" but I have had excellent luck with porcelain tile. Granite floors. Sure. But as people have said they also require maintenance like periodic sealing etc. In a house that size you don't want a different kind of floor in every room. I would stick to one or perhaps two types of floor tile in the main rooms. You can get away with additional types on walls in the bathrooms but I would keep the floors consistent. As far as cost goes, there is a very broad range of tiles and stones. In my shopping I have found some very good high quality floor tiles for reasonable prices. Stone has priced out higher...at least the ones I have looked at. Good luck!

Yogender Sharma To make a grass cover, the first thing you will need to ensure if whether the structure of the half basement is capable to holding a green roof. The next would be to waterproof the top again, keeping in mind the soil and the constant contact with water. Once these things are done, you need to locate were it is you want the lawn and ensure you have access to a drainage within or at best near it the area. You will then require the services of a horticulturist to help you set up the lawn. In terms of cost, it really depends on quite a few factors Existing condition of the structure Location Quality of Horticulturist Type of Green Cover etc....
