“How I Met Your Mother” actor Jason Segel recently purchased a charming period Pasadena traditional for $4.255 million.

The house is more than 100 years old, and stands somewhat secluded from the street by a winding drive and landscaping that is dominated by an ancient tree. Visitors pass through a white-picket fence before reaching the white home’s statement-making red door tucked beneath the clipped-gable roof.

Inside, the 5,600 square-foot five-bedroom residence has received significant modernizing. The living style is expressed in the simplicity of crisp all-white walls and light hardwood floors, and the all-white aesthetic continues from the formal living room with its fireplace to the paneled dining room and through to the gourmet kitchen.

The kitchen is especially impressive. A massive marble-topped center island, top-of-the-line stainless-steel appliances, wine fridge, and casual breakfast spot are features of the space.

The backyard is charmingly idyllic. A pergola-covered patio, a lush lawn, and a sparkling swimming pool accumulate into an unpretentious and pleasing exterior that looks eminently livable.
