Emily, with being a renter, I'd definitely check Pinterest for temporary solutions. I've seen DIYs where you can starch fabric to walls with an iron. Also try temporary wall paper/decals, but I'd test a small area first. Cabinet makers or even yourself would be able to create a flush vanity without attaching it to the wall. Plywood, especially hoop pine, has received a lot of traction. It really gives a clean, organic look that you could have custom cut to fit in the area. You could also use it on the wall – it could be stained, left natural, or painted for a feature. Have a look at EchoPanel. It is a decorative, acoustic pinboard that would add a splash of color/design. If it is above your vanity, you could pin pictures, inspirations, etc.

I love the option to work in a private office while still feeling connected to the larger open plan space. And who doesn't want a huge blackboard to creatively brainstorm?

Suzineedsahouse, what is the era or character of the house you have moved into, because perhaps that will influence design style regardless of size? Also, if you have been knocking out walls is it likely to be more open plan?? I moved from a small 1960's era granny flat into an as-small Art Deco 1940's apartment and found I went with more classic furniture with the second place because it just suited the aesthetic of high ceilings, floorboards, wide skirting boards, fireplace, ceiling roses etc. Having said that, I live in a block of 6 apartments, and I have seen the other apartments decked out completely differently (all of similar layout), from really modern, to mid-century, also one with a real retro art vibe, and they all looked great and seemed to suit the space fine. So maybe go with your taste in the end??

Am using these concepts for playspace in a Java playgroup, kindergarten & primary school. Key to success is linking & embedding into curriculum so learning is both inside & outside. Also have complementary kitchen garden for learning....and field for growing. Children are loving it.
