1. INCORPORATE MILLWORK
You can never go wrong with architectural details. Today’s design still draws upon historic Greek and Roman architecture because these styles are considered to have a “classic” look that withstands the test of time.
2. INCORPORATE NATURAL MATERIALS
The use of man-made elements, like Corian or laminate, come and go as technology and manufacturing processes change. Natural elements, however, remain classic.
3. STICK WITH A NEUTRAL PALETTE
The beauty of neutrals is that they blend into the background and let the space itself take center stage. If you keep the bones of your space in a neutral color palette, then your backdrop will be timeless and will coordinate with the rest of your space regardless of the style or color you choose for furnishings. So think beiges, whites, browns, when it comes to walls, fireplaces, trim, flooring, etc.
4. KEEP IT SIMPLE YET FUNCTIONAL
Function is one of the most important elements of a timeless interior design…after all, if it doesn’t work for you, you won’t keep it around long! In addition to function, though, look for items that are simple in the design and style.
5. USE VARIETY
Variety in decorating helps to keep a room from looking repetitive and boring, and thus extends its staying power. Using a mix of textures, metallic finishes, wood tones, materials, colors, etc. means that even if one piece goes out of style, the room itself won’t.
