Most my doors were already here, but I did have one moved over, about 6 inches. However, the entire space was demo'd, and rebuilt, so that's not the best example to draw from. If you want the door hidden, in a pocket, yes, you will need a skilled carpenter. Essentially, the opening header and frame, will become twice it's size, with the "pocket" part, hidden behind the wall. The studs/supports will need to be removed to make a space for the door to slide into. Do you have any switches or outlets on the fireplace wall?

This kind of alteration really requires an architect and a good contractor. The architect will know all the local requirements and how to meet code on everything. You will want/need to insulate the ceilings of the downstairs for sound/fire control, separate the electrical and plumbing lines, and all the things the average homeowner doesn't know or hasn't thought of. In the long run, an architect will save you money. Your friends who have remodeled may refer you to their architects. It's worth interviewing two or three in your home to see which one can help you achieve the best result.

You can look for clear glass or red back lacquered glass top coffee table with metallic legs or even wooden frame to compliment. Glass will add sheen & variety ; to take theme further add painting with same color accent in the room.

have made 3 options of the layout. in all 3 options, the best position of the media unit is on the small wall. note - L shaped sofa is in Martin colour , hanging seating is in red colour and media unit is in blue colour. option 1- the hanging seating is kept near the window but the movement will be parallel to the window (i.e. from sofa to TV unit direction) option 2- the hanging seating is kept opposite the sofa wall between the living and dining area (as a divider and for more free space) option 3- the hanging seating is again on the window wall but the movement is perpendicular to the window wall. have attached some images for your reference. do get back to us in case of any further doubts. thanks and regards, deSigneR
