Coastal Room Ideas by Birch Lane: http://www.completely-coastal.com/2016/03/coastal-decor-birch-lane.html Navy blue dining room chairs and white table. Great contrast. Not the overlook... nautical theme wall art that complements the sisal rug.
The color palette - a grey with a subtle hint of brown for the walls, white woods mixed with dark woods, and stones/tans/blues in the design elements and textiles. Also pops of bright colours would be added to this... lovely childrens and tweens playroom
