HTML5/Javascript Room Planner

HTML5/Javascript Room Planner. It allows users to choose a prexisting house/room layout or design it by themselves (Through drag and drop or choosing specific measures) in order to decorate the room by selecting different furniture options and be able to buy them. The website will work this way: Users will enter the website and choose a budget to decorate a room as well as their zip code (Automatic detection via ip address preferable). Later they will enter a screen where they will choose the room dimensions by drawing them (drag and drop) or choosing a preexisting layout. After that an interactive room will be drawn in the screen and a list of nearby furniture options (based in the zip code) from different suppliers will appear in order to decorate the room. After drag and dropping different furniture options into the room layout the budget will be lowered and the furniture will be inserted in scale of the room in order to keep designing his apartment. Users can create an account in order to save their favourite products and buy them online or share their designs via social media. The backend will allow: Furniture setup (Price, Supplier, Furniture Category Real life Picture and 2d scale picture for the layout canvas as well as sizes) Furniture Category Creation Supplier setup (Furniture owners and different products) Website User management Inventory Management Order Management (Online credit card processing) Region management (i.e: San Francisco = 500 zip codes, equal this products) I'm attaching examples of the website idea. We're looking if its possible to design this website in HTML5/Javascript combination.
