Leaving the structural walls exposed to show to bare materials like steel and concrete is another component used to achieve a modern look. If this is out of your price range or just not something you are into you can look at adding these materials/colours elsewhere. In the kitchen, it is possible to have a concrete look benchtop made out of engineered stone or laminate. Adding glass to the kitchen can be done by putting in a glass splashback in your desired colour.
There’s a preconceived idea that producing a modern appearance will create a cold, rigid and uncomfortable space. This tends to be because of the initial lack of colour which makes sense, although when done correctly adding colour becomes eye-catching and comforting. Having those neutrals as grounding tones within a modern layout setting, alongside natural lighting and minimalism, enhances the feeling of calm. The simple background colour palette minimizes the distractions and breaks the eye from bouncing around the room. It allows for a better sense of direction as you can always create an inviting space out of a simple base.
The most common ways to add texture is in the flooring and the joinery (an additional colour or profile option). A popular colour pairing is white and woodgrain. There are so many woodgrains that can create warmth in your house. In keeping with the simple base, carrying one woodgrain tone throughout the house builds on that initial base. You can add it to the flooring, the back panels of an island, or open shelving.
