Two years later... We ended up purchasing a 3-seater for wall opposite fireplace, a 2-seater for under the highlight window (leaves a comfortable space to enter the room) and an armchair placed diagonally opposite the couches. I've fooled the advice to pull the furniture in off the walls a little. We have just updated the fireplace with the (professional) installation of an insert wood heater and (DIY) replacement of hearth and tiles/timber mantel to conceal the brick while meeting the safety specifications of the heater (required a much wider/deeper hearth than the existing brick one so we removed and replaced with a slab of honed granite, and the minimum height for breastplate/mantel shelf posed a few design limitations). TV mounted above fireplace to allow for better furniture placement. Not quite the picture I had settled on 2 years ago, but works with the style of updates we have made elsewhere. Thank you for all the advice. before: After:

There are existing recessed motorised roller blinds (pale grey). The room is used as a kid's play space by day and an adult living room by night. Toys are stored in bedrooms at the end of the day and the dolls house is not a permanent fixture!

Selecting furniture in a residential interior, we carefully combine it with wallpaper and flooring, creatively compose sets and choose her companions. I haven't been a furniture planner inside a house or apartment for a long time, but a big furniture specialist in the landscape industry. In fact, as far as I am concerned, garden furniture for the country house deserves the same approach. Instead of wallpaper and parquet, we will have leaves, flowers and intertwining branches, paving, a fence, and a house facade. As in the interior, the choice will depend on the cosmetic goals that you set for yourself. It will also depend on the quality of the furniture made. You need to choose the right furniture suppliers with whom you can continue cooperating. My biggest preference is https://www.gardenfurniture.co.uk. As for me, here you can order the best garden furniture.

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.
