With a coastal scene, scale decides whether the living room wakes up. Hung large on a quiet wall, this Ha Long Bay travel poster pulls the room outside and gives it somewhere to look. The soft teal water and pale sky lift a dim corner without shouting, while the deep green foliage and limestone cliffs add the weight a plain wall needs. Hang it above a sofa, a console or a low sideboard, with the centre at eye level. It sits well with pale oak, rattan, linen and a couple of houseplants. Avoid stacking it next to busy gallery clusters, heavy florals or anything in clashing hot pink or bright red this one wants room to breathe.
