Candles in glass boxes - perfect combination of cozy and contemporary. Using flameless/electric candles for this would be a good idea to not have to worry about melting wax oozing into the bottom of the glass box and onto the other decorative objects
Love the double sided fireplace. Grey and white make wonderful companions in a modern open plan space. Add a little texture and pattern, soft lighting and some carefully chosen accessories, then sit back and relax .
