Example of varying textures. Black, grey and white palette looks elegant - love the detail on wainscoting! Mixture of patterns on sofa and large silver jars add more texture. Grasscloth wallpaper brings in nature and even more texture!
Delightful variation on the conservatory - a hexagonal wall of arched windows under a glass doomed roof with quarry tile floor makes for an intimate dining room. Maybe mirrors could be used in lieu of windows?
