FOCUS The focus for this family was to create an outdoor adventure that could be an athletic, social and personal outlet for their entire family while maintaining the natural beauty of the landscape and without altering the sweeping views from the home. The large scale of the challenging obstacles is camouflaged within the landscape using the rolling hills and mature trees as a natural curtain in every season. The beauty of the course does not diminish the functional and demanding nature of the obstacles which are designed to focus on multiple strength, agility, and cardio fitness abilities and intensities. STORAGE The start of the trail includes a raised training area offering a dedicated space clear from the ground to place bags, mats and other equipment used during the run.

Each obstacle is paired with an instructional sign directing the runners in proper use of the obstacle, adaptations for skill levels and tips on form. These signs are all customized for this course and are printed on metal to ensure they last for many years. SAFETY Safety is crucial for all physical activity and an obstacle course of this scale presents unique safety concerns. Children should always be supervised when participating in an adventure on the course however additional care was paid to details on the course to ensure everyone has a great time. All of the course obstacles have been created with pressure treated lumber that will withstand the seasonal poundings. All footer pilings that support obstacles have been placed into the ground between 3 to 4 feet (.9 to 1.2 meters) and each piling has 2 to 3 bags of concrete (totaling over 90 bags used throughout the course) ensuring stability of the structure and safety of the participants. Additionally, all obstacle lumber has been given rounded corners and sanded down offering less splintering and more time for everyone to enjoy the course. This athletic and charismatic family strives to incorporate a healthy active lifestyle into their daily life and this obstacle course offers their family an opportunity to strengthen themselves and host some memorable and active events at their amazing home.

Spectacular unobstructed views of the Bay, Bridge, Alcatraz, San Francisco skyline and the rolling hills of Marin greet you from almost every window of this stunning Provençal Villa located in the acclaimed Middle Ridge neighborhood of Mill Valley. Built in 2000, this exclusive 5 bedroom, 5+ bath estate was thoughtfully designed by architect Jorge de Quesada to provide a classically elegant backdrop for today’s active lifestyle. Perfectly positioned on over half an acre with flat lawns and an award winning garden there is unmatched sense of privacy just minutes from the shops and restaurants of downtown Mill Valley. A curved stone staircase leads from the charming entry gate to the private front lawn and on to the grand hand carved front door. A gracious formal entry and wide hall opens out to the main living spaces of the home and out to the view beyond. The Venetian plaster walls and soaring ceilings provide an open airy feeling to the living room and country chef’s kitchen, while three sets of oversized French doors lead onto the Jerusalem Limestone patios and bring in the panoramic views. The chef’s kitchen is the focal point of the warm welcoming great room and features a range-top and double wall ovens, two dishwashers, marble counters and sinks with Waterworks fixtures. The tile backsplash behind the range pays homage to Monet’s Giverny kitchen. A fireplace offers up a cozy sitting area to lounge and watch television or curl up with a book. There is ample space for a farm table for casual dining. In addition to a well-appointed formal living room, the main level of this estate includes an office, stunning library/den with faux tortoise detailing, butler’s pantry, powder room, and a wonderful indoor/outdoor flow allowing the spectacular setting to envelop every space. A wide staircase leads up to the four main bedrooms of home. There is a spacious master suite complete with private balcony and French doors showcasing the views. The suite features his and her baths complete with walk – in closets, and steam showers. In hers there is a sumptuous soaking tub positioned to make the most of the view. Two additional bedrooms share a bath while the third is en-suite. The laundry room features a second set of stairs leading back to the butler’s pantry, garage and outdoor areas. The lowest level of the home includes a legal second unit complete with kitchen, spacious walk in closet, private entry and patio area. In addition to interior access to the second unit there is a spacious exercise room, the potential for a poolside kitchenette, second laundry room, and secure storage area primed to become a state of the art tasting room/wine cellar. From the main level the spacious entertaining patio leads you out to the magnificent grounds and pool area. Designed by Steve Stucky, the gardens were featured on the 2007 Mill Valley Outdoor Art Club tour. A level lawn leads to the focal point of the grounds; the iconic “Crags Head” outcropping favored by hikers as far back as the 19th century. The perfect place to stop for lunch and take in the spectacular view. The Century old Sonoma Olive trees and lavender plantings add a Mediterranean touch to the two lawn areas that also include an antique fountain, and a charming custom Barbara Butler playhouse. Inspired by Provence and built to exacting standards this charming villa provides an elegant yet welcoming environment designed to meet the needs of today’s active lifestyle while staying true to its Continental roots creating a warm and inviting space ready to call home.

Penza Bailey Architects was contacted to update the main house to suit the next generation of owners, and also expand and renovate the guest apartment. The renovations included a new mudroom and playroom to accommodate the couple and their three very active boys, creating workstations for the boys’ various activities, and renovating several bathrooms. The awkwardly tall vaulted ceilings in the existing great room and dining room were scaled down with lowered tray ceilings, and a new fireplace focal point wall was incorporated in the great room. In addition to the renovations to the focal point of the home, the Owner’s pride and joy includes the new billiard room, transformed from an underutilized living room. The main feature is a full wall of custom cabinetry that hides an electronically secure liquor display that rises out of the cabinet at the push of an iPhone button. In an unexpected request, a new grilling area was designed to accommodate the owner’s gas grill, charcoal grill and smoker for more cooking and entertaining options. This home is definitely ready to accommodate a new generation of hosting social gatherings. Mitch Allen Photography
