Our team will focus our effort around (3) key areas during new construction or remodeling your existing home:
Comfort
Functional lay–out
Lower energy usage
We wouldn’t feel right building you a project that we know is going to cost you a lot of money over the long term. We are a quality builder and a firm believer of planning, organization and a skilled work force.
We have added another feature to all our new construction projects recently. In addition to the free installation of the water purification system in our new kitchens, we are installing an electric car charger in the garage and solar panel lines to the roof for future use at no charge.
This is all part of our goal as your builder to lower the energy usage as well as purifying the air and water inside our new homes & remodels.
We are proud members of both the Pacific Palisades and the Santa Monica Chamber of Commerce.
