So you like purple? Please buy soft lavender curtains, or some with purple printed flowers, I've had dark purple curtains in my old house (3meter high ceilings) and it looks really dark when they're closed. Add a purple sofa or lots of purple accents to keep it calm and friendly. You could paint the window wall a deep eggplant (not the other walls because of light) with creamy curtains.

Most of the ceiling looks like veneer on plywood and the balance is plain gypsum . If so , then just polish the veneer either in the same shade of wood as your furniture or one tone darker or lighter . The gypsum ceiling can remain white . If the ceiling height is too low , do not go for a jhoomer but rather a simple mounted light. Good Lighting is key to any design to look good.

It’s great you're focusing on recycling! If the dado tiles are in good condition and neutral, you can leave them, but check grout and overall security. When replacing bathroom floor tiles, ensure the waterproofing layer remains intact, as redoing it can prevent water damage. For plywood, if the quality is good, you can reuse it, but ensure a skilled carpenter finishes it properly. The kitchen countertop can be reused if carefully removed and in good shape. Just make sure all structural and waterproofing aspects are intact.
