- [Entertainer's Showcase](https://www.houzz.com/hznb/projects/entertainer-s-showcase-pj-vj~600919)
  - Location: Menlo Park, CA
  - Photos: 9
  - Description: The backyard of this Menlo Park home was spacious but woefully underused. There was little sense of place, and an expanse of grass required costly, frequent watering and time-consuming upkeep. The owners of the property knew they had an exciting opportunity. The right combination of elements would create a much-needed area for entertaining while making a dramatic lifestyle statement. We began this challenging project by establishing the must-haves: an outdoor kitchen, dining space, and drought-r…

  - Location: Fremont, CA
  - Photos: 8
  - Description: A total backyard remodel to reflect the entertaining lifestyle of the homeowners. The only things that were kept from the original yard were the mature fruit trees along the back fence. We designed a custom wood burning pizza oven with stone color selected to pick up accent from the interior of the home, with a custom made copper roof. The heavy beam wood arbor was designed to create the feel of an outdoor room with the pizza oven used as the central feature. Lighting and custom gas heaters were…

  - Location: Saratoga, CA
  - Photos: 8
  - Description: This graceful stone manor is discreetly tucked into a Saratoga enclave. The owners wanted landscaping that matched the beauty of the surrounding area but were mindful that the hillside setting could cause problems. The designers at Koch & Associates understand that landscaping on a slope leaves little margin for error. This project called for drainage and grading designed and installed with precision. It's a given that California landscapes today should be drought-tolerant. Our use of artificial…

  - Location: Saratoga, CA
  - Photos: 14
  - Description: To our landscape designer for this project in Saratoga, CA, it was immediately obvious the backyard had the potential to be the showpiece of this sumptuous estate. The client had visions of transforming the nondescript but spacious area into both a retreat after a hectic day and a gathering spot for friends and relatives. The property owners wanted a backyard design that deftly used nature to soften the look of a considerable amount of hardscape. They chose Koch & Associates because of our exten…

  - Location: Los Gatos, CA
  - Photos: 10
  - Description: The craftsman style home sits on a large hillside property overlooking Silicon Valley. From a non-usable hillside, we designed and constructed fun outdoor entertaining area that would take advantage of the fabulous views. We designed the backyard stone patio to transition from the old stone patio to the new stone patio. Twin fountains were also integrated into the retaining wall and garden balcony to visually extend the yard area with a small lawn. The stone retaining wall was built with a custo…

  - Location: San Jose, CA
  - Photos: 8
  - Description: To create the hardscape for this large San Jose home, our Koch & Associates designer took inspiration from the finest country clubs and spas. With a home of more than 8,000 square feet, the outdoor landscaping needed to utilize its size and layout for poolside entertainment, eating and relaxing. The property was dotted by swaying palm trees and surrounded by a softscape that was in good shape, so our client chose to focus on renovating the hardscape in the rear of the home. The task of the Koch…

  - Location: Pleasanton, CA
  - Photos: 10
  - Description: andscaping in California often means dealing with hillsides. Like so many clients of Koch & Associates, the owners of this sloping Pleasanton property wished for a landscape that looked natural and needed little maintenance but was an attractive setting for parties and get-togethers. Issues such as irrigation and slope stability needed to be addressed but had to be artfully incorporated into the final design. Terracing the slope with a series of retaining walls built of small boulders was one so…
