SITED ON A PARCEL with awe-inspiring ocean and marshland vistas, this Osterville retreat is designed to let the landscape take center stage at all times. “Summer, winter, fall, even when it’s raining — it doesn’t matter, the view is magnificent,” says Boston-based designer Cynthia Driscoll, who worked with the owners to create the home’s interior. In deference to the scenery, Driscoll steered clear of bright colors and patterns in favor of beiges in various textures. For visual interest, she incorporated items with appealing shapes. Beige, as it turns out, can be beautiful.
