Modernizing Marin County
In idyllic Mill Valley of Marin County, CA, there is an interesting trend happening. People are building again. They’re updating their old homes to fit their modern lifestyles. In many cases, they’re starting over with their properties and building new custom homes.
Here’s a look at one of our projects in the area.
The owners of a hundred-year-old, outdated home in Mill Valley needed more space for their family, which includes two children.
They realized they had made a good investment in purchasing the property. After all, its value had appreciated an average of 8.9% per year over the last four decades, and it will likely continue to appreciate. They also knew moving would take them away from their local schools and might mean they’d have to pay for private schools. So instead of moving, they decided to replace the existing structure with a new custom home.
The first architect they hired wasn’t a good fit. Unhappy with the way their project had started, the homeowners came to New Avenue for help.
New Avenue handled the planning and building permits, getting this project off on the right foot.
New Avenue’s architects know the triggers that can stop a building permit and know how to manage that process. The permitting process, which takes three months, but most of the time the inspectors are exceptionally good.
Because this property is in a regulated flood zone, the owners would not be allowed to change the home’s footprint. Marin also places restrictions on square footage.
Our New Avenue partner architect designed a two-story custom home that will meet these requirements, give the family much more space, and modernize the outdated home.
The new home will have a design for modern living and an open floor plan. Included are an au pair suite, a master bedroom suite, bedrooms upstairs, an outdoor entertaining area, and an office.
Other upgrades include high-quality windows to prevent drafts, air sealing around the entire envelope, radiant heating, heat recovery, and indoor air quality control. Plus, the design makes use of all the finishes we love: solid wood floors, wood trim, marble counters, and tile baths and backsplashes. The family will enjoy modern appliances, beautiful sinks, and quality faucets. To improve safety, the design makes use of modern earthquake and seismic structural engineering .
