If you are working with an architect or interior designer, I would suggest creating a basic furniture layout, which will involve making choices in terms of which couches, end tables, lamps, coffee tables, et al, you plan to furnish the room with. This will guide the placements of where to place outlets. Randomly placing them without guidance may create problems, in terms of limiting how the room can be furnished, and outlet locations, whether in floor or in wall, are not cheap to move once installed. Work with a professional to maximize your benefits, while minimizing your uncertainty. Happy Houzzing.
