The picture on the right shows the 12 foot tall walls of the future media room and one of the 2′ x 4′s used to help support our wall against the neighbor’s house. Picture 1 and 2 below show the supports for the one foot thick suspended concrete slab on the garage level. Picture 3 is a view towards the street that shows the side of the neighbor’s house and our wall. In order to build a foundation that had adequate bearing capacity, we needed to underpin the neighbor’s foundation by 20 feet. Underpinning extends the foundation support to depths that provide greater bearing capacity and prevent foundation settling. In this case we used footings and constructed a 20 foot tall wall using shotcrete as seen in Picture 4. Picture 5 shows one of the workers beginning the framing process by laying down the floor sill. The 2 x 4′s used for the framing of the home will anchor into the sill.

The nearly 14 feet tall portion of the foundation shown here is what will be the media room on the second floor. The concrete walls are well suited for sound insulation, making this space ideal for a home theater. In another picture, the backyard stairwell is being prepped for waterproofing and forms. One section of the backyard will feature an outdoor BBQ area spanning 25 by 20 feet and the other section is an elevated backyard area that will have landscaping, grass and Jaccuzi connections.

Due to the location of a neighbors house and the walkway that runs the length of the lot, the West side of the property gets lots of direct sunlight for much of the day. Some of the windows on the top level facing West will be floor to ceiling, taking advantage of the surrounding views and the natural light provided by the large windows and skylights.

The pictures below show the foundation about three-fourths of the way complete. The crew is pictured using the shotcrete method to construct one of the walls of what will be the media room, which is located above the garage level. Requiring nearly 30 cement trucks carrying 9 yards of concrete each to complete, the new foundation is nearly ready for the framing of the house to begin.

With the excavation of the site complete, the difficult process of building the foundation begins at the rear of the property. In total, about 260 yards of concrete were poured, reinforced by a tied rebar beam cage. The varying grade elevations add to the difficulty, requiring one of our retaining walls to stand nearly 20 feet tall. This wall, like most others for this project, were constructed using a method called shotcrete, a process that involves spraying the concrete under pressure and smoothing the walls by hand.
