Designing a simple house interior involves creating a clean, uncluttered, and functional space with a focus on practicality and comfort. Here are some steps to guide you in designing a simple interior for your house:

1. Define Your Style: Decide on the interior style you want to achieve. Simple interior design ideas often lean towards minimalism, Scandinavian, or contemporary styles. Each style has its characteristics, so choose the one that resonates with your preferences.
2. Declutter and Organize: Start by decluttering your space and getting rid of unnecessary items. Keep only essential and meaningful items to maintain a clean and uncluttered look.
3. Neutral Color Palette: Opt for a neutral color palette with light tones such as whites, beige, grays, and pastels. Neutral colors create a calming atmosphere and make the space feel open and airy.
4. Functional Furniture: Choose furniture pieces that are functional and comfortable. Stick to clean lines and avoid excessive ornamentation. Consider multifunctional furniture like storage ottomans or foldable tables to save space.
5. Open Layout: If possible, create an open floor plan to promote a sense of spaciousness and flow between rooms. Eliminate unnecessary walls to allow natural light to penetrate deeper into the space.
6. Minimalist Decor: Keep decor to a minimum. Select a few carefully curated pieces, such as artwork, plants, or simple decorative items, to add personality to the space without overwhelming it.
7. Use Natural Light: Maximize natural light by keeping windows unobstructed and using light curtains or blinds. Natural light enhances the simplicity and freshness of the interior.
8. Practical Storage: Incorporate ample storage solutions to keep belongings organized and out of sight. Built-in cabinets or shelves help maintain a clutter-free environment.
9. Simple Window Treatments: Choose simple and understated window treatments that complement the overall design. Sheer curtains or basic blinds work well for a simple interior.
10. Focus on Texture: Introduce texture through fabrics, rugs, or cushions to add warmth and interest to the space without compromising the overall simplicity.
11. Thoughtful Lighting: Invest in quality lighting fixtures to create the right ambiance. Use a combination of overhead lighting, task lighting, and accent lighting to enhance functionality and aesthetics.
12. Personal Touches: Add a personal touch through family photos or meaningful artwork. These small touches can make the space feel more welcoming and inviting.

Remember, simplicity in interior design tips is not about a lack of style but about intentional choices that create a serene and harmonious living environment. Keep your design consistent, and focus on creating a space that reflects your lifestyle and brings you joy and comfort.
