2 sofas look great when you are needed extra seating for people but i really like the armchair /wingchair idea with a sofa. As you have chosen a modern take on deco i would look at a side table that encumpases that style but as said functionality is key. No good having one sofa if you have 5 guests. It sounds so beautiful so keep moving with your ideas and remember that sometimes ideas can change with different advise but you have to love it

We built our house in 1975 and had a similar problem; A teeny tiny family room with too many doors. After several years of squeezing ourselves into this poorly functioning excuse of a "family" room, which has entrances in every corner bar one, plus an entry into the kitchen and sliding door to outside, in a fit of frustration, I decided that our under-utilised formal lounge/dining would be used as a living room with the TV, although we chose to keep the dining table in that room as it is a long narrow room. I made this change 26 years ago. The family room is now just a sitting area with one 2.5 seater couch and a side table at each end, no TV and is a great space for a few people to congregate in to keep the cook company or just to read. However it would have worked equally well with the dining table there. In any case, because of all the doorways, it is really just a walk-through area, but now feels spacious and "settled" instead of crowded and messy. I can recommend the change.....you will feel much less at "sixes and sevens" with your home.

If you have a lounge with a chaise it will not fit five people comfortably. Someone will be always having to put their feet up, and guests may not want to do that. I would have a two, and a three seater, at right angles, and single lounge chairs you can bring into the space if needed. This will allow for a table in corner, which you can't have with a modular corner lounge.

It's interesting to see the differences -- turning the flash on certainly makes the rooms look a lot better ! While some of the colours and the like are definitely better , I personally look more for honest before and after pictures as a gauge of a good decorator .
