This is a dilemma indeed! Posts in the middle of rooms are always a little difficult. It would be helpful to have pictures of all four walls to suggest the best layout. From what I can understand of your dilemma, I've attached a layout that may work based on your description. It features a defined entry. So when you walk through the front door, you will see a console table with a couple of ottomans stashed beneath. They can come in handy for extra seating. In front of the console are two arm chairs, followed by a modular sectional - they make up your main seating area. To the right of the kitchen door is a TV console. Behind the sofa is a bookcase and to the right is a round table with a couple of chairs for games, paper work or what have you. You don't mention any windows. Is this the case? If so, we'll want to make sure you've got adequate lighting and colors that will work with the limited light. Hope this helps!

How is the bathroom design coming along? Did you already finalize the layout or are you still in the planning phase?

We have done it a few times. The greatest breakage chance is around the electrical plug locations. Care needs to be taken that the voids are filled and that the metal is kept from making contact wit the glass. A little care here makes using the plugs safer and adds less stress on the glass. Not all paints are equal. Make sure you check the references of the installer. this look can go horribly wrong if a newbie is in charge of the painting.

Why not go for a portico verandah style for the both sit out and car porch? You can see the images in google or houzz photo
