Welcome to The Simonds House, a secluded haven of beauty and a masterpiece even by the standards of its renowned architect, Theodore Pletsch. Designed with the philosophy that living spaces shape our happiness, this exquisite Modern Ranch offers rare comfort and tranquility on over 35,000 sqft of manicured grounds in prestigious Linda Vista. From the quiet street, the residence appears cheerful and understated--but as you pass through the entry, a world of casual elegance and luxurious spaciousness unfolds. Both inside and out, you'll find a uniquely warm and inviting atmosphere that encourages unforgettable hosting and simple, everyday closeness with loved ones. Showcase spaces include the stunning living room and nearby sunroom, which offers peaceful views of the majestic backyard. Landscaped to perfection, this sprawling outdoor wonderland elevates every occasion, be it an adventurous outdoor sleepover under the stars or a bustling charity gala with a live band and 150+ guests. The massive deck--which spans the length of the home--offers multiple seating areas and plenty of space for caterers while fruit trees, a picturesque koi pond with a bridge, and a sparkling saltwater pool/spa create an enchanting backdrop. The renovated dream kitchen is a natural gathering place, complete with a huge island and Viking appliances, and the home's entire main level is united by a 50 ft hallway, creating a perfect sense of harmonious flow. With its original floor plans preserved at the Pasadena Museum of History, 1650 Knollwood is a home of exceptional provenance that offers an equally exceptional lifestyle.
