Here's an idea for a small bar in a corner that you could close off with beautiful draperies. The second photo shows a pretty bar cart which could hold the necessary items, and the third photo is of a simpler butler's tray.

Please treat the mould properly to kill it and remove as it can be a serious health hazard.

I have a few suggestions. Hope these will help. Go for a wooden sofa set. I know many people nowadays tend to go for fabric sofa sets and sectionals, but i fee that wooden sofas never go out of style. Also, you can change the upholstery colour any time if you want a more colourful look or a colourful slip cover (you can get a local uphostery guy to custom stitch one) which can be washed easily. Go for sleek furnitures that are not heavy. You can also add a few accent furniture pieces like an accent chair if the space allows for it. There are couple of things to note when you bring in colour. Choose one primary colour and maximum two secondary colours. See these links to [pep up your space[(https://www.houzz.in/magazine/is-your-living-room-too-brown-here-are-8-ways-to-pep-it-up-stsetivw-vs~101141558) and liven it. After you choose your colours, pick your decor. Add dashes of these colours through cushions, vases, flowers, paintings, figurines, curtains, carpets and other decor pieces. If you have a favourite painting, pick your accent colours from them. Or if you like the colours in a particular cushion covers, the other pieces can be colour matched. Always hang your paintings at eye level. I noticed that your hang your frames quite high up. Place them around 57 - 60 inches from the floor. Hope I could help

Hello Shivani, For antique look, you can use an indian wooden swing as one seating on one of the sides of the seating, for wall treatment you can also go for pop textures with rust color on the wall. For the sofa go for a light color like beige or creme, with bright color cushions. You can also go for one seating in a contrast or bright color. Attaching reference pictures.
