Where can I get wall designs, colors and textures for showrooms, franchisee shop  

It looks fab guy. Really Hightech and with the times. Wall designs, colours and textures you can get at any household store no? I don't know if you mean like paint, paintings, and stucco and the like. We get that kind of stuff from like Wal Mart or Jysk out here. Now, if you are looking for that kinda stuff on the inter web, sadly I can be of no really assistance to you.

Cheers, and best of luck in all you do.

I have to say that I absolutely love the design of this showroom. It seems like it is very hip and very modern. It would be a very successful place in my honest opinion.

Okay, as far as where you would be able to find your textures and such for the walls. The first place that I would think about would be a store that specializes in building/home remodeling. Here we have Lowe's and Home Depot but I don't know what you have available in your neck of the woods. Somewhere like that would be able to help you get what you needed and also be able to steer you in the right direction.

As far as colors texture patterns, you can use clip art or use photo shop to create what you like and then incorporate them in your work. The design looks nice, but seems incomplete? need an entrance, windows, and from this point of view a functionality explanation and work flow for the users on site. Its a show room so where are the items being showed?, there are no shelves, and showcases of product. I see work stations. What are those sculpture looking things for? The wall colors lack harmony and the wall picture style is to Victorian for the modern contemporary room style.
