Hi Angela, this space has mega potential. For starters it has fantastic symmetry. However as the space is very long I would recommend you break it down into 2 zones. The front zone as the place for bride and bridesmaids to get ready and the end wall zone as the sleeping area. Divide the space with a set of luxurious pooling drapes, and keep the lighting in the sleeping zone dimmable wall hung bedside lights and and a conversation piece chandelier. Go for warm colours and a touch of gold. A high oversized shallow tufted bedhead will add luxe. A upmarket Bohemian theme could work well. The bridal preparation zone needs to be well lit, (daylight) bars, with floor to ceiling opposable mirrors, (side lit also). Remember this is a functioning space, there needs to be ample hanging for dresses/clothing, clear space, formalish seating (no bride or bridesmaid wants to get stuck in a low lounging sofa and need a hand-up. Have sideboard space for jewellery, flower holders etc and keep the colour palette very neutral, a blackwhite, and mid range neutral grey will work with any bridalware. If you would like any further advice you are welcome to contact me. As an interior designer I often work alongside a styling company that specialises in weddings and other events.

You could install racking for both sides of the room, toys & clothes that aren't being used can go into large plastic containers with lids. The two bikes could be hung from the wall or ceiling. And yes, anything that doesn't need to be there, move it on. There are so many hooks and storage options available that it would be very easy to sort this out and by getting a lot of it off the floor.

My very first thought was to paint the ceiling white. Some colourful artwork would be nice I think. I see you have some blue cushions, so some art with that colour would be helpful to tie it together and also a rug on the floor. What about a lampshade with a shiny chrome stand A tallish plant or two in white or pale coloured pots placed somewhere on the TV wall. I see something else on the back of the lounge suite that looks an interesting colour. Wouldn't hurt to bring that colour into the room too.

How about something like the below up and down wall lights in a black/dark charcoal. Up and down beams can be adjusted and when lit at night, they will show off beautifully the linear cladding.
