I would start with a loft like room, with exposed brick and large windows. Something like this.
A gorgeous hammered sink like this….
Installed into something like this antique table. Oh it needs a faucet too!
The table can also support a microwave and kettle with tea/coffee supplies. Some baskets would fit nicely onto that lower shelf to keep supplies looking tidy. And a small bar fridge beside it.
Some shelves made of reclaimed wood are a lovely idea for storing art supplies but I love these so much I want them in my kitchen to.
A rustic metal cabinet for more storage of creative supplies.
A sofa and some cozy pillows in case I need a nap.
An easel and table for my painting and collaging. And maybe two of those tables so one can be for sewing.
I could keep on filling up this room with both practical and beautiful things.
I think it needs some dramatic drapes so I’ll just add one more thing…..
This is too much puddling on the floor, but I think these rich looking velvet drapes will do quite nicely.
