I also agree with the neutral lounge to be jazzed up with coloured pillows and such. It won't be too much with your feature walls plus, if your taste changes, you paint or you move down the track, the beige will be a lot easier to work with :)

I had a 2nd hand lovely resort style lounge (cane with fabric) which quickly became pulled and tatty after my 2 small dogs had been using it. The leather lounge & two large leather recliners I have show no damage (regardless of long or clipped nails) and both pets love these. Having a blanket the dogs know is theirs is a great idea especially with leather, as the initial cold feeling of leather means both dogs only want to be on the blanket.

It would be great to see the room or ideas of the style you are going for, but as a simple suggestion perhaps you could have a warm cosy throw blanket on the couch that could double as a blanket for when the sofa is transformed into a bed? some artwork or a mirror on the wall would add some character if you don't have any already and maybe suggest a candle or diffuser with a cosy/homely scent on a small side table (which doubles as a bedside also).

I am coming in very late to this discussion. But is there enough room in your space to move the furniture like this? I have moved your wooden coffee table where the couch is, and moved the cabinet so it is not the first thing you see as you enter. Moving the grey side tables to form one “modular” table creates a uniform look that doesn’t sacrifice functionality. The marble side table would then be used next to the other couch (as the cabinet is where it used to be) I would also take up the whole space between the aircon and the floor to hang your ‘family’ picture frames. The gorgeous plant is then placed on top of the coffee table to become the hero in the space. I noticed you used a grey soft looking throw blanket on the couch to the right. Is it possible to get matching versions of this to cover the sofa against the wall for the dogs? The texture and colour of the sheets you are currently using is what disconnects your lovely couch from the rest of the space. Regardless of what artworks you choose to use for above the couch, having a darker frame will help to ground them in the space. The white frames are getting lost against the white brick wall at the moment. You have great taste in furniture, it seems to be editing the layout of the space that is not quite working in your zone. Hope this helps!
