I would add some bright scandinavian style furniture... Scandinavian style often features grey, grey sofas, walls, or floors. But paired with vibrant sot furnishings it looks fresh and inviting. Hit up ikea for ideas. it will add colour and vibrancy without being too stark and they have some nice styled kids stuff and storage that will be practical but look good. Yellow looks nice with grey... add some oversized floor cushions and pouffs for the kids to relax on. Add some vibrant art and posters and it won't look too austere.

Do you want modern or classic look. China white for classic it changes from grey-to light greenish colour I have it in the same facing room, or for more contemporary try Big white from Taubmans , it's a white with a bit of grey in it very soft. With your grey sofa I would stay away from darker greys and north facing room can make it really dark in the afternoon.

Interesting range of comments - Is it that there is a general shift towards an industrial trend? Topic is far too close for comfort, as I have a bathroom being tiled in a couple of days, have had tiles for a couple of months now, so doubt does set in!! A while back I probably thought I would go towards a traditional look, but looks like I have moved towards the industrial - which the family are fully supportive of - young adults and husband. Our home is . . . transitional, though I hesitate labelling it. Also these images make me wonder if a cool grey is a more traditional look and a warm grey more representative of an industrial look or modern look? These are my tiles: Left pale grey/white for ensuite floor and walls, with white cabinetry work, centre mid grey for family bathroom & laundry floor, with white cabinetry work, right mid grey to darker grey for a large open plan area of kitchen/dinning/small sitting area. They all feature flecks of whites, greys, taupes, even tans and blue greys.

Hi Carla,love oklouise ‘s ideas, My most favourite chair is the iconic butterfly, throw a fur over it and it looks beautiful, I think a tan leather will go with your couches, add a rug, some stylish cushions , plants and it could look gorgeous
