A traditional pitched roof can be replaced with a flat or shed roof to give your home a more contemporary look. You could also add skylights or solar panels to the roof to let in more natural light and help reduce your energy bills.
Another way to change up your simple home design is by playing with the exterior finishes. Use modern, bold colours like blue, yellow, green, red, and purple instead of more traditional white, grey, or black paint. The outside of the home reflects an internal side of the modern house interior!
