The legendary Old Castle Road House, designed and built by renowned architect Kendrick Bangs Kellogg, has actually debuted on the marketplace for the very first time. Standing atop a 40-acre parcel in California’s Valley Center, this stunning natural masterpiece liquifies the limit in between sculptural architecture and nature. Its smooth, wavy roofline and natural-material scheme, set amidst avocado groves, blends perfectly with the softly curved terrain of the hillside.
The construction of the huge Old Castle Roadway House took 6 years. A family bought a piece of land in 1972 and planted 900 avocado trees. Amidst these groves, the architect Kendrick Bangs Kellogg created the sculptural house in 1984 at his customers’ request. To develop your home, he in your area sourced natural materials from the building and construction site and hand-built the stone-clad walls to give it a striking handcrafted appearance.
The biophilic aspects, consisting of floor-to-ceiling glazed walls and a rustic, textured lumber framework, further highlight the structure’s stone-clad exterior. Its fluid geometry and softly curved silhouette mimic the natural terrain, making your home look like an extension of the landscape itself. The designer entirely prevented sharp or rigid boxy elements to get rid of visual blockage and maintain its attractive flowy style.
For its interior, the designer kept the sculptural element by using stone, raw wood log pillars, and generous glazing in each room. The flowy path gives a sensation of roaming through a dense forested location. These wooden pillars offer structural assistance to the building and subtly different numerous zones in spite of the open floor design. The huge glazed walls flood the interior with natural light and deal 360-degree views of the rocky landscape.
The living zone looks like an elevated watching platform covered with enormous wall glazing. The drifting stone fireplace adorns the area with its monolithic look and includes tactile richness to the interior. It rests on the circular platform that seems to drift above the floor. The windows, directly set into the wood columns, eliminate the need for bulky frames and offer undisturbed views of the surroundings.

The kitchen looks like a natural art piece with its curved countertops, cabinetry, and circular dining table in the middle. The tree trunks act as natural structural dividers while giving unrestricted views of the surrounding and different levels in the two-story building. Intimate locations like the five bedrooms maintain strong natural appeal through exposed beam ceilings, incorporated stone fireplace, glazing, and raw wood pillars.
The aqua ceramic tilework works as a striking decoration element in the 3 restrooms and contrasts magnificently against the stone columns. The double vanity island with a double-sided circular mirror doesn’t obstruct the natural light passing through the space.
The method the designer incorporates biophilic elements into every minute information of the Old Castle Roadway House turns it into a splendid natural architectural work of art. Kendrick Bangs Kellogg’s home is listed with Representatives of Architecture for $2,695,000.
