Let the exterior set the tone for the interior with these façade materials that exhibit a range of styles. Mosaics that feature elaborate geometric patterns in stone and glass are perfect for a luxurious detail, such as a border around windows and doors. Create an earthier vibe with volcanic stone, multicolored rock-faced limestone and porcelain tile in a plasterlike finish. Metals and ceramics in high-octane colors won’t let a façade blend into the landscape. Mix and match tiles for a more eclectic look, or keep it classic by using marble slabs with strong veining or unusual color.
