I need an interior designer to help transform our spare bedroom into a wfh office/ guestbedroom

We have a spare room that we would like to transform into a wfh office / guest bedroom( maybe a sofa bed?) we would like to keep the room fairly neutral and flexible in its purpose as we would like the ability to transform it into a nursery down the road. Some ideas we had was to have a foldable desk thats mounted to the wall and or a sofa bed etc . Whilst the room is small we have a lot of wall space that could be utilised for shelves , desk etc
