Introduction
A beautiful living space is not only created by expensive items, but also by the arrangement, choice of materials, colors, and lighting to ensure overall harmony. This is the art of interior design – where creativity and technique merge seamlessly.
With many years of experience in full-package interior design, production, and construction, De Line has distilled 5 golden principles that can make any space – whether an apartment, townhouse, or villa – refined, luxurious, and inspiring.
1. Balance Proportions and Overall Layout
Proportion is the first factor that determines aesthetics in interior design. A sofa that is too large for a small living room, or a dining table that is too small for a large room, can make the space feel unbalanced.
De Line architects always start by carefully measuring the actual area and allocating space appropriately for each zone.
Balance is reflected through:
-
Furniture size proportionate to the room’s area.
-
Clear circulation space, without overlap.
-
Harmonious height–width–lighting ratio.
When the layout is balanced, the space feels open, comfortable, and more luxurious.
2. Choose a Suitable Primary Color Palette
Color is the “emotional language” in interior design. It directly affects how people perceive a space.
A space with a refined color palette brings relaxation, while mismatched tones can feel chaotic or heavy.
De Line often advises clients to select three main color tones for each space according to the 60 – 30 – 10 rule:
-
60% base color (walls, floor, ceiling)
-
30% secondary color (main furniture)
-
10% accent color (decor, accessories, artwork)
For example, a living room could use white–beige as the base and highlight with walnut wood or olive green. This combination creates a warm yet modern and sophisticated feeling.
3. Lighting – Creating Spatial Depth
Lighting not only illuminates but also “breathes life” into every corner of the home.
A beautiful interior design always requires a harmonious combination of natural and artificial lighting.
At De Line, architects maximize natural light through windows, skylights, sheer curtains, or transparent glass. In addition, lighting fixtures are arranged in layers:
-
Ceiling or recessed lights for ambient lighting.
-
Wall-wash or pendant lights for decorative accents.
-
Table and floor lamps for task lighting.
This refined combination makes the space lively, deep, and much more comfortable.
4. Use Consistent and Refined Materials
Materials are key to expressing a space’s style. However, combining too many different materials can make the overall design look cluttered and less elegant.
De Line recommends choosing no more than 3–4 main materials for the entire house, e.g., wood, stone, glass, and metal.
-
Natural wood or veneer-finished engineered wood provides warmth and coziness.
-
Stone or tile cladding creates elegance and durability.
-
Glass and metallic finishes enhance modernity and brightness.
Thanks to its own furniture workshop, De Line can finely craft every detail, ensuring material consistency – from kitchen cabinets, beds, TV shelves to doors and decorative panels.
5. Create Highlights and Unique Identity for Each Space
