Walls in Farrow & Ball Lamp Room Gray Estate Emulsion, Floor in Pigeon Floor Paint and radiator in Wimborne Estate Eggshell White (We just did the dining room in our own home with almost the same colour scheme)
Monochrome chic. Simple is best in a narrow hallway. White painted stairs make them appear wider and the grey runner is both practical and elegant. Seek out a slim console - vintage or modern - thats useful and decorative but not space-consuming.
