Interior design is often mistaken for a purely intuitive "eye for beauty." However, the most successful rooms—those that feel both comfortable and visually stunning—are actually built upon a foundation of seven fundamental elements.

Have you ever looked at a professionally styled coffee table or bookshelf and wondered why it looks so "right," while your own arrangement feels a bit stiff or cluttered? The secret often lies in a fundamental principle of human psychology and visual art: The 3-5-7 Rule.

Creating a room layout is the most critical phase of interior design. It is the architectural "skeleton" upon which all your aesthetic choices—colors, textures, and decor—will hang. A well-planned layout ensures that your room is not just beautiful, but functional, comfortable, and balanced.

One of the most common dilemmas in home styling is knowing when to stop. You have a beautiful collection of art, shelving ideas, and mirrors, but the question remains: how many walls in a room should actually be decorated?

The question "How much should I spend on interior design?" is one of the most common—and stressful—for any homeowner undertaking a renovation or decoration project. Unlike buying a car, there's no fixed price tag. The cost is highly subjective, influenced by the scope of work, your desired quality level, and where you live.

Whether you are moving into a new home, renovating a single room, or simply rearranging furniture, visualizing the final space is the hardest part. Hiring a professional designer might not be in the budget, but thanks to modern technology, the power of spatial planning is now available for free.

The world of interior design is often perceived as subjective, ruled by taste and trend. Yet, beneath the layers of colour swatches and fabric samples lies a foundation of mathematical principles that guide truly successful spaces. Among these principles, the 60/40 Rule stands out as a simple yet powerful guideline for achieving balance, flow, and visual appeal in any room.

What was once a niche hobby has now become a mainstream way to plan interiors and renovations online.
