Use Light-Colored Walls and Ceilings
Light colors reflect more sunlight, making spaces appear brighter and more open. Consider using whites, light grays, or pastel shades on walls and ceilings to enhance the natural light in your south-west facing house.

Strategic Use of Mirrors
Mirrors can amplify natural light by reflecting it throughout the room. Place mirrors opposite windows or in areas where light naturally falls to maximize brightness in your south-west facing flat.

Sheer Curtains and Window Treatments
Sheer curtains allow sunlight to filter through while providing privacy. For more control over light levels, consider layering sheer curtains with heavier drapes that can be drawn as needed.

High-Quality Blinds and Shades
Invest in blinds or shades that can effectively block out the intense afternoon sun. Cellular shades, roller blinds, and venetian blinds are excellent choices for a house facing south-west. Look for options with thermal linings to provide additional insulation.

Thermal or Blackout Curtains
Use thermal or blackout curtains to reduce heat gain during the hottest part of the day. These curtains can help keep indoor temperatures more comfortable and protect furniture from UV damage.

Window Films
Apply UV-protective window films to your south-west facing windows. These films can reduce heat gain and glare while still allowing natural light to enter. They also help protect your interior furnishings from fading.

Exterior Awnings and Shades
Install awnings, pergolas, or exterior shades to provide additional sun protection. These solutions can significantly reduce heat gain and glare while allowing you to enjoy your outdoor spaces comfortably. 

Heat-Resistant Flooring
Select flooring materials that can withstand high temperatures and are less prone to fading. Tiles, especially ceramic or porcelain, and engineered hardwood are durable and stylish options that work well in sunlit areas.

Breathable Fabrics
Use natural, breathable fabrics like cotton, linen, or bamboo for upholstery, cushions, and bedding. These materials are comfortable and help maintain a cooler indoor environment.

Furniture Placement
Arrange furniture to avoid direct sunlight during the hottest part of the day. Place seating and work areas where they can benefit from natural light without being exposed to intense sun and heat.

Indoor Plants
Incorporate indoor plants that thrive in bright light. Plants like succulents, ferns, and spider plants not only enhance the aesthetic appeal but also improve air quality and provide a cooling effect.

Ventilation
Ensure proper ventilation to maintain a fresh and cool indoor environment. Use ceiling fans, exhaust fans, and strategically placed windows to allow for cross-ventilation.

Reflective Surfaces
Use reflective surfaces in your decor, such as glass tables, metallic accents, and glossy finishes, to bounce light around the room and enhance the overall brightness.
